previous patches for Software Release 2.2.2, and the following enhancements:
PCR: 02498 Module: VLAN Network affecting: No
The correct protocol number is now returned by VLAN Relay.
PCR: 03172 Module: FIREWALL Level: 3
Telnet access from a public interface to another public interface was not
denied. This issue has been resolved.
PCR: 03241 Module: FIREWALL Level: 2
When deleting a list associated with a policy, all rules were being deleted.
Now only the rules associated with the policy and list are deleted.
PCR: 03412 Module: FIREWALL Level: 3
FTP data transfers did not succeed for some types of NAT. Also, the
presence of flow control TCP flags meant that some TCP control packets
were not recognised. These issues have been resolved.
PCR: 03415 Module: FIREWALL Level: 2
When using a policy routing rule, the firewall did not translate the source
IP address of a broadcast packet correctly. This issue has been resolved.
PCR: 03416 Module: SWI Level: 3
Previously, the ADD SWITCH L3FILTER MATCH command was accepted
if the TYPE parameter was not specified. This command now requires the
TYPE parameter, and an error message will be returned if the TYPE
parameter is not specified.
PCR: 03420 Module: IPG, SWI Level: 3
It is now possible to prevent specified ports from acting as IGMP all-group
ports, and specify which ports are allowed to behave as all-group entry
ports. This is enabled with the ENABLE IP IGMP ALLGROUP command,
and disabled with the DISABLE IP IGMP ALLGROUP command.
For details, see “IGMP Snooping All-Group Entry” on page 42.

4 Patch Release Note
PCR: 03438 Module: DHCP Level: 3
A warning message will now appear if the DESTROY DHCP POLICY
command is executed for a DHCP policy that has been used by one or more
policies as the source of their configuration information. A parent policy can
be destroyed with no affect on its child policies.
The new message is:
The destroyed policy <policy-name> has been used by another policy as a source of
configuration information.
PCR: 03446 Module: SWI Level: 3
After unplugging a fibre uplink cable and then plugging it back in, a short
Ping timeout occurred. This issue has been resolved.
PCR: 03457 Module: OSPF Level: 2
Disabling OSPF caused a fatal error if there was a large routing table. This
issue has been resolved.
PCR: 03458 Module: IPG Level: 3
The route information for ipRouteEntry of ipGroup in the MIB-II MIB was not
correct. This issue has been resolved.
PCR: 03465 Module: DHCP Level: 2
The IPMTU parameter in the ADD DHCP POLICY command was
accepting values in the range 0-4294967295. This parameter now accepts
values in the correct range of 579-65535.
PCR: 03475 Module: NTP Level: 3
The PURGE NTP command did not change the UTC offset to the initialised
value. This issue has been resolved.
PCR: 03482 Module: SWI Level: 3
When a Rapier using switch silicon received a multicast packet, the
ifOutError port counter was erroneously incremented. This issue has been
resolved.
PCR: 03484 Module: FIREWALL Level: 3
The firewall was not denying an ICMP packet, even if ICMP Forwarding
was disabled when using Standard NAT. This issue has been resolved.
PCR: 03496 Module: IPG Level: 2
Sometimes CPU utilisation reached its maximum limit when an IGMP
Membership Report was received. This issue has been resolved.
PCR: 03499 Module: IPG Level: 2
The SET TIME command caused an error on Refresh timers for IGMP
groups. This issue has been resolved.
PCR: 03506 Module: DHCP Level: 2
When receiving a request from a client in the Renewing state, the DHCP
server incorrectly added an ARP entry for that client’s IP address. Also, the
DHCP server allocated an entry while the entry was being reclaimed, and
this interrupted the reclaim process. These issues have been resolved.

Patch 86222-27 For Rapier Switches 5
PCR: 03526 Module: SWI Level: 3
The Switch MIB did not show the correct dot1StpPriority value. This issue
has been resolved.
PCR: 03531 Module: SWI Level: 3
After creating a trunk group, the activity LEDs did not flash unless the
configuration was used at reboot. This issue has been resolved so that the
LEDs flash correctly whenever a trunk group is created.
PCR: 03572 Module: STP Level: 3
The dot1dStpPortForwardTransitions value in the dot1dBridge MIB was not
incremented correctly when STP transitioned a port to the Forwarding state.
This issue has been resolved.
PCR: 03574 Module: STP Level: 3
The dot1dStpInfoTopChanges value in the dot1dBridge MIB was not
incremented correctly when a topology change was detected by the bridge.
This issue has been resolved.
PCR: 03576 Module: IPG Level: 2
When the device received a route from two separate sources to the same
destination network, RIP only used the metric value when selecting the best
route. RIP now selects the route by lowest preference value, or if they are the
same, by the metric.

PCR: 02300 Module: Firewall Network affecting: No
If the command ADD FIREWALL POLICY RULE SOURCEPORT=ALL was
executed, a value of “65535” was incorrectly displayed for the
SOURCEPORT parameter for that rule in the SHOW FIREWALL POLICY
command. This issue has been resolved.
PCR: 02400 Module:
Network affecting: No
CORE,FFS,FILE,INSTALL,SCR
If a problem occurred with NVS, some critical files were lost. As a result, the
equipment was forced to load only boot ROM software at boot time. This
patch combined with the new version of the boot ROM software (pr1-1.2.0
for the AR700 series) resolves this issue.
6 Patch Release Note
PCR: 02530 Module: FIREWALL Network affecting: No
The GBLIP parameter in the ADD FIREWALL POLICY RULE
ACTION=NONAT command is optional. However, if the command was
executed without the GBLIP parameter set, the command erroneously
failed after a CREATE CONFIGURATION command was executed. This
issue has been resolved.
PCR: 03111 Module: FIREWALL Level: 1
TCP sessions could fail if the public side of the firewall was using Kerberos
and the private side had a very slow connection to the firewall. This issue
has been resolved.
PCR: 03134 Module: TCP Level: 2
When using the SET TELNET LISTENPORT command, a fatal error
sometimes occurred. This issue has been resolved.
PCR: 03135 Module: SWI Level: 2
The TYPE parameter in the SET SWITCH L3FILTER command was not
written to the script file correctly if MATCH was set to NONE. This issue
has been resolved.
PCR: 03143 Module: VRRP Level:
When the PRIORITY parameter in the SET VRRP command was changed,
it was not set correctly when a link was reset. This issue has been resolved.
PCR: 03145 Module: IPG Level: 4
The SET IP ROUTE FILTER command was not processing some parameters.
This issue has been resolved.
PCR: 03148 Module: IPG Level: 3
If the Gratuitous ARP feature was enabled on an IP interface, and an ARP
packet arrived, (either ARP request, or reply) that had a Target IP address
that was equal to the SenderIP address, then the ARP cache was not
updated with the ARP packet’s source data. This issue has been resolved.
PCR: 03160 Module: STP Level: 2
Executing the PURGE STP command caused fatal error. This issue has been
resolved.
PCR: 03171 Module: DVMRP, IPG Level: 3
DVMRP was erroneously forwarding packets to a VLAN with a
downstream neighbour. This issue has been resolved.
PCR: 03173 Module: CORE, NTP Level: 3
The default NTP polling interval was set to 64 seconds, not the correct
interval of 128 seconds. This issue has been resolved.
PCR: 03174 Module: IPG Level: 2
This PCR corrects issues that arose with PCR 02203. When the DNS request
forwarding queue failed to accept a new DNS request message (possibly
due to overloading), an attempt was made to close the UDP sessions for
both the primary and secondary name servers. This caused a restart if either

C613-10319-00 REV Z
Patch 86222-27 For Rapier Switches 7
one of these servers did not exist, or the UDP session had failed to open.
This issue has been resolved.
PCR: 03180 Module: IPG Level: 3
If all 32 VLAN interfaces had IP addresses attached, only 31 VLANs could
be multihomed. Now all 32 VLAN interfaces with IP addresses can be
multihomed.
PCR: 03202 Module: CORE Level: 3
There are two sources of time kept in the device. The real time clock, and the
milliseconds since midnight (msSinceMidnight). The msSinceMidnight can
reach midnight slightly before the real time clock which means that the
value of the msSince Midnight is larger than the number of milliseconds in
a day. This meant that at midnight, the elapsed time since the time-to-live
value for the Firewall and IP-NAT TCP sessions appeared very large and
Firewall and IP-NAT sessions were prematurely aged out. This issue has
been resolved by pausing the msSince Midnight variable at midnight to
wait for the real time clock to catch up.
PCR: 03217 Module: DVMRP Level: 2
If a DVMRP interface was deleted and then added again, DVMRP routes
associated with this interface were not reactivated. This issue has been
resolved.
PCR: 03218 Module: DVMRP Level: 2
Some issues with DVMRP forwarding have been resolved.
PCR: 03236 Module: IPG Level: 3
IGMP queries were being sent after IGMP was disabled. This issue has been
resolved.
PCR: 03240 Module: OSPF Level: 2
A fatal error occurred when OSPF was under high load. This issue has been
resolved.
PCR: 03253 Module: FIREWALL Level: 2
Inbound TCP sessions through the firewall (e.g. Telnet and FTP) failed when
the PORT parameter was set to ALL in the SET FIREWALL POLICY RULE
command. This issue has been resolved.
PCR: 03255 Module: FIREWALL Level: 3
Patch 86222-27 for Software Release 2.2.2
C613-10319-00 REV Z
The firewall doubled the IPSPOOF event timeout from 2 minutes to 4
minutes. This issue has been resolved.
PCR: 03302 Module: SWI Level: 3
Following a period of high traffic load, the CPU utilisation would
occasionally fail to drop below 40%. This issue has been resolved.
PCR: 03314 Module: SWI Level: 2
Layer 3 filters that matched TCP or UDP port numbers were being applied
to the second and subsequent fragments of large fragmented packets. This
issue has been resolved.
8 Patch Release Note
PCR: 03332 Module: TTY Level: 2
A log message is now created when a user is forced to logout from an
asynchronous port when another user (i.e. someone connected via Telnet)
resets the asynchronous connection with the RESET ASYN command.
PCR: 03346 Module: SNMP Level: 4
Sometimes the Agent Address field in SNMP traps was not the same as the
IP source address. This meant that sometimes the NMS did not send an
alarm to the network manager when traps were received from switches.
This issue has been resolved.
PCR: 03368 Module: SWI Level: 2
Layer 2 packets transmitted out of the mirror port were being tagged
erroneously. This issue has been resolved.
PCR: 03378 Module: DHCP Level: 2
DHCP sometimes suffered a fatal error when a range of IP addresses was
destroyed. This issue has been resolved.
PCR: 03385 Module: FILE, INSTALL, SCR Level:
Critical files (prefer.ins, config.ins and enabled.sec) are now copied from NVS
to FLASH at boot time if they do not exist in FLASH, or if the NVS version
of the file is different from the FLASH version.
PCR: 03386 Module: SWI Level: 2
If the SET SWITCH L3FILTER MATCH command had nothing specified for
the IMPORT and EMPORT parameters, and there was an existing match
entry in the filter table, the new filter was not added correctly. Filter match
entries are now accepted regardless of the order in which they are entered
into the table.
PCR: 03388 Module: DHCP Level: 3
The DHCP lease Expiry time showed incorrectly in the SHOW DHCP
CLIENT command when the lease straddled across multiple months and
years. This issue has been resolved.
PCR: 03402 Module: IPG Level:
IP routes deleted from the route cache occasionally caused a fatal error. This
issue has been resolved.

Patch 86222-23 includes all issues resolved and enhancements released in
previous patches for Software Release 2.2.2, and the following enhancements:
PCR: 02071 Module: NTP Network affecting: No
When a NTP packet was received from an NTP server (mode 4) the router
acted as a client, and sent a reply back to the server, but did not remove the
peer association. This meant that the Dynamic Peers list, viewed using the
SHOW NTP command, displayed incorrect dynamic peer associations. This
issue has been resolved.
PCR: 02202 Module: FIREWALL/IP NAT Network affecting: No
Previously, when Firewall or IP NAT was enabled, any fragmented IP
packets had to be reassembled so they could be processed. If the fragments
could not be reassembled, the packet was dropped. Reassembly could only
occur if the combined packet (IP header, and protocol header, and data) was
no more than 1800 bytes. An additional limit of no more than eight
fragments was also imposed. This PCR implements enhanced fragment
handling for Firewall and IP NAT. Each module can now be configured to
process fragmented packets of specified protocol types without needing to
reassemble the packet. The number of fragments a packet may consist of is
also configurable. This enhanced fragment handling is disabled by default.
Patch 86222-27 for Software Release 2.2.2
C613-10319-00 REV Z
To enable enhanced fragmentation for Firewall, use the command:
ENABLE FIREWALL POLICY=policy_name
FRAGMENT={ICMP|UDP|OTHER}
To enable enhanced fragmentation for IP NAT, use the command:
ENABLE IP NAT FRAGMENT={ICMP|UDP|OTHER}
To disable enhanced fragmentation for Firewall, use the command:
DISABLE FIREWALL POLICY=policy_name
FRAGMENT={ICMP|UDP|OTHER}
To disable enhanced fragmentation for IP NAT, use the command
DISABLE IP NAT FRAGMENT={ICMP|UDP|OTHER}
To configure the number of fragments permitted per packet for Firewall, use
the command:
SET FIREWALL FRAGMENT=8...50
To configure the number of fragments permitted per packet for IP NAT, use
the command:
SET IP NAT FRAGMENT=8...50
10 Patch Release Note
TCP has been excluded from this enhancement because TCP has the MSS
(Maximum Segment Size) parameter for segment size control. Also, for
PPPoE interfaces with a reduced MTU of 1492, a previous enhancement in
PCR 02097 ensures that TCP MSS values in sessions carried by a PPPoE
interface are clamped to a value that prevents fragmentation.
PCR 02116 Module: IPG PING Network affecting: No
When pinging to a remote IP address with two or more different cost routes,
if the preferred route became unavailable, the ping failed to switch to the
less preferred route until the ping was stopped and restarted. This issue has
been resolved.
PCR: 02371 Module: FIREWALL Network affecting: No
When the system time was set to a time that was before or significantly after
the current time, Firewall sessions were prematurely deleted. This issue has
been resolved.
PCR: 03011 Module: OSPF Network affecting: No
When the router priority was changed on a dynamic OSPF interface, the
new priority did not appear in the output of the SHOW OSPF NEIGHBOUR
command on neighbouring routers. The new priority only showed after the
RESET OSPF command was executed on the neighbouring routers. This
issue has been resolved.
PCR: 03026 Module: IPG Network affecting: No
After setting the IGMP query timer with the SET IP IGMP command, and
saving the configuration, the IGMP Other Querier timeout was not set to the
correct value after a restart. This issue has been resolved.
PCR: 03027 Module: DHCP Network affecting: No
Entries in the process of being reclaimed as static entries (and waiting for
the remote IP to become routable), were disrupting the reclaim process. This
prevented further entries from being reclaimed. DHCP static entries are
now fully subject to normal reclaim processing.
PCR: 03032 Module: SWI Network affecting: No
If the ENABLE IP IGMP command was executed before the ENABLE
SWITCH L3FILTER command, Layer 3 filtering did not discard packets
destined for the CPU. This issue has been resolved.
PCR: 03035 Module: OSPF Network affecting: No
Link state advertisements could incorrectly show an area as a stub area. This
happened during the time when a Direct Route (DR) was removed from a
configuration and before a Direct Backup Route (BDR), or an Other Direct
Route (Other DR) was elected. This issue has been resolved.
PCR: 03040 Module: IPG Network affecting: No
Sometimes IP flows were not deleted correctly when both directions of the
flow were in use. This issue has been resolved.
PCR: 03065 Module: SWI Level: 2
When the TX cable was unplugged from a fibre port the operating status
was incorrectly reported as UP. This issue has been resolved.

PCR: 03067 Module: DHCP Level: 1
When replying to a DHCP REQUEST that had passed through a DHCP
relay, the broadcast bit of DHCP NAK messages was not being set. This
issue has been resolved in accordance with RFC2131.
PCR: 03080 Module: DVMRP
DVMRP was not updating the downstream forwarding state correctly. This
issue has been resolved.
PCR: 03095 Module: DHCP Level: 2
DHCP policies are no longer stored in alphabetical order in the DYNAMIC
CONFIGURATION script because this did not work when the DHCP
INHERIT parameter was used.
PCR: 03122 Module: SWI Level: 2
When a static ARP was added to a trunk group, a software restart could
occur. This issue has been resolved.

PCR 02136 Module: FIREWALL Network affecting: No
The firewall was blocking outbound ICMP packets when the associated
private interface had a ‘deny all’ rule. The passing of ICMP packets should
be controlled by the ICMP_FORWARDING and PING parameters. This
issue has been resolved.
PCR 02184 Module: FFS FILE TTY Network affecting: No
This patch supersedes PCRs 02073, 02081, 02086 and 02105. In addition to
enhancements in the preceding PCRs, this PCR now also resolves the
following issues:
• If a compaction was started within 60ms of a file write commencing, the
file being written was placed in the wrong location in the file system.
This led to file corruption during subsequent compactions.
• If a file load occurred during compaction, an incomplete copy of the file
was loaded. The load also put the file into the wrong part of the file
system once the compaction had moved beyond the part of the file that
had been loaded.
• A fatal error occurred during compaction if a file was marked as deleted
when it was being transferred.
• Sometimes during compaction when the file system was erasing blocks
belonging to deleted files, one of the files was transferred rather than
deleted. However, its directory entry was deleted, so the file was not
visible with a SHOW FILE command but was visible with a SHOW
FFILE command.
• During compaction if the amount of free space was less than two erase
blocks (including the "spare" erase block), the file system erroneously
reported that a large amount of space was available for a new file due
to an underflow problem. When a new file was written it would corrupt
existing data.
Patch 86222-27 for Software Release 2.2.2
C613-10319-00 REV Z
Patch 86222-27 For Rapier Switches 13
• If the file system was completely full and the deletion of a single file led
to a compaction, the file system reported that it was continually
compacting. This was because it was repeatedly searching through a
linked list of file headers.
• A byte of data from FLASH was incorrectly returning the value 0xFF.
• When a file was renamed using upper case letters, the renamed file did
not appear in the file directory but did appear in FLASH. Also, if a
SHOW FFILE CHECK command was executed after renaming the file,
the file system would appear to hang. All file names must now be lower
case.
• Multiple TTY sessions could edit the same file. This caused
unpredictable behaviour when the TTY sessions closed the files.
A new command, SHOW FFILE VERIFY, has been added. This command
steps through the file system headers starting with file zero and finishing at
the end of the last reachable file. It then verifies that all FLASH locations
from the end of the last reachable file to the beginning of file zero are in an
erased state. Errors are reported as they are found.
PCR 02192 Module: IP Network affecting: No
The source IP address in DVMRP prune and graft messages was incorrect.
This issue has been resolved.
PCR: 02241 Module: FIREWALL Network affecting: No
Firewall subnet NAT rules were not working correctly from the private to
the public side of the firewall. Traffic from the public to private side
(destined for subnet NAT) was discarded. These issues have been resolved.
ICMP traffic no longer causes a RADIUS lookup for access authentication,
but is now checked by ICMP handlers for attacks and eligibility. If the ICMP
traffic matches a NAT rule, NAT will occur on inbound and outbound
traffic. HTTP 1.0 requests sometimes caused the firewall HTTP proxy to
close prematurely. Cached TCP sessions were sometimes not hit correctly.
These issues have been resolved.
PCR: 02359 Module: IPG Network affecting: No
When an IP Multihomed interface was used as an OSPF interface,
neighbour relationships were only established if the IP interface for OSPF
was added first in the configuration. Now, OSPF establishes neighbour
relationships regardless of the IP Multihomed interface configuration order.
PCR: 02395 Module: VRRP, TRG Network affecting: No

When the switch was under heavy learning load, some MAC address were
lost. This issue has been resolved.
PCR 02506 Module: OSPF, IPG Network affecting: No
In the ADD IP ROUTE FILTER command, when the optional parameter
INTERFACE was included, the filter was not applied to the flooding of
OSPF external LSAs. Also, in the command SHOW IP ROUTE FILTER, the
output of the interface name was truncated when the name was more than
six characters long. These issues have been resolved.
PCR: 02509 Module: DVMRP Network affecting: No
The source net mask has been removed from DVMRP prune, graft and
graft-ack messages.
PCR 02526 Module: DVMRP Network affecting: No
Under some circumstances, multiple default routes were created for
DVMRP. This issue has been resolved.
PCR 02538 Module: DVMRP Network affecting: No

Patch 86222-21 includes all issues resolved and enhancements released in
previous patches for Software Release 2.2.2, and the following enhancements:
PCR: 02167 Module: FIREWALL Network affecting: No
Locally generated ICMP messages, that were passed out through a firewall
interface because they were associated with another packet flow, had their
source address changed to that of the associated packet flow and were also
forwarded with incorrect IP checksums. This only occurred when there was
no NAT associated with the packet flow. This issue has been resolved.
PCR: 02236 Module: FIREWALL Network affecting: No
Sometimes the retransmission of an FTP packet was not permitted through
the Firewall. This issue has been resolved.
PCR: 02245 Module: VRRP Network affecting: No
VRRP returned an incorrect MAC address for an ARP request. This issue
has been resolved.
PCR: 02327 Module: IPG/FIREWALL Network affecting: No
In some situations, multihomed interfaces caused the Firewall to apply
NAT and rules incorrectly when packets were received from a subnet that
was not attached to the receiving interface. This issue has been resolved.
PCR: 02329 Module: DHCP Network affecting: No
An ARP entry for a host has been removed whenever a DHCP DISCOVER
or DHCP REQUEST message is received from the host. This allows for
clients changing ports on a switch.
PCR: 02332 Module: IPSEC Network affecting: No
The sequence number extracted from the AH and ESP header was in the
wrong endian mode, which caused an FTP error with IPSEC anti-replay.
This issue has been resolved.
PCR: 02343 Module: PPP Network affecting: No
When acting as a PPPoE Access Concentrator (AC), if a PPPoE client sent
discovery packets without the "host-unique" tag, the discovery packets sent
by the AC were corrupted. This issue has been resolved.

C613-10319-00 REV Z
16 Patch Release Note
PCR: 02368 Module: IPG/IGMP Network affecting: No
IGMP failed to create an automatic IGMP membership with no joining port
when it received multicast data that no ports were interested in, when IP
TimeToLive was set to 1 second. Also, IGMP erroneously sent a query on an
IGMP enabled IP interface even when IGMP was disabled. These issues
have been resolved.
PCR: 02374 Module: SWI Network affecting: No
In the ADD SWITCH L3FILTER command, the EPORT parameter
incorrectly accepted the value 62-63 as multicast and broadcast ports 63-64.
This issue has been resolved.
PCR: 02397 Module: DVMRP Network affecting: No
After a prune lifetime had expired, the interface was not joined back to the
DVMRP multicast delivery tree. This issue has been resolved.
PCR: 02404 Module: IPG Network affecting: No
DVMRP multicast forwarding failed to send tagged packets to a tagged
port. Packets were erroneously sent untagged to tagged ports. This issue
has been resolved.

Patch 86222-27 For Rapier Switches 17
PCR: 02024 Module: IPG Network affecting: No
Proxy Arp can now be used on VLAN interfaces.
PCR: 02122 Module: FIREWALL Network affecting: No
A fatal error sometimes occurred if a TCP session originating on the public
side of the firewall sent packets before the session was established with the
host on the private side of the firewall. This issue has been resolved.
PCR: 02128 Module: FIREWALL Network affecting: No
Some FTP packets handled by the firewall were forwarded with incorrect
sequence numbers, causing FTP sessions to fail. This issue has been
resolved.
PCR: 02150 Module: CORE, SNMP Network affecting: No
When passing 64-bit counters in an SNMP packet, only the lower 32 bits
were passed. Now the full 64 bits of the counter will be returned if all are
required.
PCR: 02158 Module: FIREWALL Network affecting: No
When a TCP RST/ACK was received by a firewall interface, the packet that
was passed to the other side of the firewall lost the ACK flag, and had an
incorrect ACK number. This issue has been resolved.
PCR 02161 Module: IPG Network affecting: No
The IP Filter SIZE parameter was not being applied correctly. This issue has
been resolved.
PCR 02162 Module: IPG Network affecting: No
The SET IP FILTER command would not update the SIZE parameter
correctly. This issue has been resolved.
PCR 02172 Module: IPG Network affecting: No
The TOS field in IP packets was not being processed by IP POLICY filters
with an identifier greater than 7. This issue has been resolved.

If a port on a Rapier 48 or Rapier 48 i went down, some associated entries
were not promptly removed from the forwarding, Layer 3 and default IP
tables. This issue has been resolved.
PCR: 02198 Module: DHCP Network affecting: Yes
This PCR includes the following enhancements:
• A new command, SET DHCP EXTENDID allows for multiple DHCP
clients, and handling of arbitrary client IDs on the server.
• Static DHCP entries now return to the correct state when timing out.
18 Patch Release Note
• DHCP entry hashes now have memory protection to prevent fatal
errors.
• DHCP client now retransmits XID correctly.
• Lost OFFER messages on the server are now handled correctly.
• The DHCP server now correctly handles DHCP clients being moved to
a different interface on the DHCP server after they’ve been allocated an
IP address.
PCR: 02203 Module: IPG Network affecting: No
Responses to DNS requests received by a DNS relay agent, and forwarded
to the DNS server, were returned to the requester with a source IP address
of the DNS server rather than the DNS relay agent. This issue has been
resolved.
PCR: 02208 Module: LOG Network affecting: No
Log messages are no longer stored in NVS.
PCR: 02214 Module: IPG Network affecting: No
A buffer leak occurred when a large number of flows (over 4000) were in use
and needed to be recycled. This issue has been resolved.
PCR: 02215 Module: FILE Network affecting: No
When the only feature licence in the feature licence file was disabled, the
licence file stored on FLASH memory did not change. This was due to a
previous enhancement in PCR 02184 which prevented existing files being
deleted before a new version was stored. This issue has been resolved.
PCR: 02220 Module: SWI Network affecting: No
The EPORT parameter in the ADD SWITCH L3FILTER ENTRY and SET
SWITCH L3FILTER ENTRY commands was matching multicast and
broadcast packets with software filtering. This issue has been resolved.
PCR: 02224 Module: SWI Network affecting: No
Some switch chip register values have been changed to improve QoS
support on Rapier G6 and Rapier G6f switches.

ASSERT debug fatal error. This issue has been resolved.
PCR: 02246 Module: VRRP Network affecting: No
The ARL entry for the virtual router MAC was incorrectly showing a
numerical value. The entry now shows the CPU’s port value.
PCR: 02250 Module: FIREWALL Network affecting: No
Sometimes the Firewall erroneously used NAT. This issue has been
resolved.
Patch 86222-27 for Software Release 2.2.2
C613-10319-00 REV Z
Patch 86222-27 For Rapier Switches 19
PCR: 02259 Module: DHCP, IPG Network affecting: No
A dual Ethernet router was incorrectly accepting an IP address from a
DHCP server when the offered address was on the same network as the
other Ethernet interface. An error is now recorded when DHCP offers an
address that is in the same subnet as another interface.
PCR: 02260 Module: TTY Network affecting: No
When a ‘\n’(LF) character was received, the router/switch did not
recognise this as the termination of a command over Telnet. This issue has
been resolved.
PCR: 02262 Module: DNS Network affecting: No
Responses to MX record requests were not handled correctly if the preferred
name in the MX record differed from the one that was requested. This issue
has been resolved.
PCR: 02263 Module: VRRP Network affecting: No
The virtual MAC address was used as the source MAC for all packets
forwarded on an interface associated with a Virtual Router (VR). This was
confusing when multiple VRs were defined over the same interface because
only one virtual MAC address was ever used. The other virtual MAC
addresses (for the other VR's) were only used if the source IP address
matched the VR’s IP address. To avoid this confusion, the system MAC
address is now always used unless the source IP address of the packet is the
same as the VR’s IP address.
PCR: 02264 Module: PIM, DVMRP, SWI Network affecting: No
PIM or DVMRP failed to see any data if IGMP snooping was on and
DVMRP or PIM was enabled after the data stream had reached the router/
switch. This issue has been resolved.
PCR: 02265 Module: FIREWALL Network affecting: No
MAC address lists were not working with Firewall rules. This issue has
been resolved.
PCR: 02268 Module: FIREWALL Network affecting: No
HTTP requests from a fixed IP address were erroneously reported as a host
scan attack in the Firewall deny queue. This issue has been resolved.
PCR: 02269 Module: DUART, TM Network affecting: No
Under certain circumstances, the Asyn Loopback Test failed. This issue has
been resolved.
PCR: 02274 Module: TPAD Network affecting: No
ARL message interrupts have been re-enabled after a software table rebuild
to fix synchronisation of the software forwarding database with the
hardware table.

C613-10319-00 REV Z
PCR: 02275 Module: OSPF Network affecting: No
Some routes were not added into the OSPF route list, and therefore were not
added into the IP route table. This issue has been resolved.
20 Patch Release Note
PCR: 02276 Module: FIREWALL Network affecting: No
The CREATE CONFIG command did not save the SOURCEPORT
parameter to the configuration file when the low value of the source port
range was set to zero. This issue has been resolved.
PCR: 02287 Module: IPG Network affecting: No
Existing IGMP groups were not deleted when IGMP was disabled globally
or on the associated interface. This gave the groups very high timeout
values. This issue has been resolved.
PCR: 02299 Module: VRRP Network affecting: No
If a packet with a destination IP address equal to a VRRP IP address was
received when the router didn’t own the IP address, (because it didn’t have
an interface with that IP address) the router incorrectly tried to forward the
packet and send an ICMP “redirect” message to the source. Now, if such a
packet is received, it will be discarded and an ICMP “host unreachable”
message will be sent to the source.
PCR: 02304 Module: VRRP Network affecting: No
VRRP used the wrong source IP address in ICMP redirects. RFC 2338 states
that the source IP address of ICMP redirects should be the IP address that
the end host used when making its next hop routing decision. In the case of
a packet sent to a VRRP virtual MAC address, this is the primary VRRP IP
address associated with the MAC address, provided such a VR exists and is
in the master state. This issue has been resolved.
PCR: 02317 Module: IPG Network affecting: No
The SIZE functionality on the IP filter was not working for IP fragmented
packets. This issue has been resolved.

Patch 86222-19 includes all issues resolved and enhancements released in
previous patches for Software Release 2.2.2, and the following enhancements:
PCR: 02018 Module: OSPF Network affecting: No
When OSPF was calculating routes from an AS external LSA and the AS
external router had two next hops with different metrics, the router
erroneously added two routes instead of one route with the best metric. This
issue has been resolved. Also, when the two equal cost routes were on the
same IP interface, but to different next hops, the router sent the packets to
the wrong MAC address. This issue has been resolved.

C613-10319-00 REV Z
Patch 86222-27 For Rapier Switches 21
PCR: 02098 Module: STP Network affecting: No
STP always transmits untagged packets. If a port does not belong to a
VLAN as an untagged port, then the port must belong to one VLAN as a
tagged port. In this case, STP should transmit VLAN tagged packets out of
the port.
PCR: 02123 Module: IPG Network affecting: No
The IP, MASK, and ACTION parameters could not be set with the SET IP
ROUTE FILTER command. This issue is resolved when the filter number is
specified at the start of the command, for example:
SET IP ROUTE FILTER=filter-id IP=ipadd MASK=ipadd
ACTION={INCLUDE|EXCLUDE}
where: filter-id is the filter number. Filter numbers are displayed in the
output of the SHOW IP ROUTE FILTER command.
PCR 02138 Module: SWI Network affecting: No
The built in Self Test Code for all Rapiers, except G6, has been improved to
enhance the detection of faults in switch chip external packet memory.
PCR 02140 Module: OSPF Network affecting: No
An AS boundary router advertises AS external LSAs to other routers.
However, when the router’s configuration changed, either by adding an IP
route filter, or by setting its ASEXTERNAL parameter to OFF using the SET
OSPF ASEXTERNAL command followed by a restart, its neighbour state
could not reach full state. Also, when the router had IP route filters
configured, matched routes were not being flooded into other routers.
However, these routes should still have been imported into the router’s
own LSA database, but were not. These issues have been resolved.
PCR 02144 Module: IPG Network affecting:No
The IPG module has been enhanced to support gratiutous ARP request and
ARP reply packets.
PCR 02151 Module: IPG Network affecting: No
The Rapier was not detecting invalid checksums in ICMP echo request
packets. This issue has been resolved. ICMP echo request packets with
invalid checksums are now dropped and the ICMP inErrors and inDiscards
counters are incremented.
PCR 02164 Module: DHCP Network affecting: No
A simple DHCP range MIB and a trap have been added. The trap is
triggered when a DHCP request cannot be satisfied. The gateway address
and the interface address are sent as trap variables. The range table shows
which range was exhausted. A debug variable,
swiDebugBroadcomParityErrors has been added to the SWI module MIB to
count the SDRAM parity errors in the packet memory of the Broadcom
switch chip.

PCR 02181 Module: LOAD Network affecting: No
When a file upload was interrupted, the file being uploaded was not
unlocked. The file could not be deleted without restarting the router. This
issue has been resolved.
PCR 02186 Module: IPG Network affecting: No
RIP was incorrectly sending triggered request packets over VLANs, even on
non-demand links. This issue has been resolved.
PCR 02188 Module: VRRP Network affecting: No
When VRRP responded to an ARP request for the VR IP address it was not
making an entry in the ARP table and the switch L3 table. This issue has

PCR: 02041 Module: SWI Network affecting: No
In some situations, the switch would stop forwarding packets via internal
and/or external uplink ports. This issue has been resolved.
PCR: 02073 Module: FILE Network affecting: No
If a flash write error occurred when a file was being written, the file’s
directory entry was deleted leaving a partial file in flash. Subsequent
attempts to write the file failed because a file of the same name already
existed. This issue has been resolved.
PCR: 02075 Module: OSPF, IPG Network affecting: No
In configurations containing a large number of OSPF routes, the SPF
calculation could take a long time. During this calculation, other events
would not be processed. This patch reduces the time required for an SPF
calculation and allows the switch to respond to other events in the mean
time. This patch also improves the performance of flow cache updates.

If the FILE module was required to re-write a file, the existing file would be
deleted before the size of the new file was known. This issue has been
resolved.
PCR: 02082 Module: OSPF Network affecting: Yes
OSPF virtual links running across a single network segment would accept
0.0.0.0 as the next hop address. This was inherited by derivative routes,
making them unusable. This issue has been resolved.
PCR: 02086 Module: FFS Network affecting: No
If a file ended short of an erase block boundary and a compaction was
started, the block in which the file was stored was not erased, causing errors
when new files were written. Also, if the last file in the filing system ended
on or short of an erase block boundary, and a compaction was started, then
compaction would fail. These issues have been resolved.
PCR: 02088 Module: SWI Network affecting: No
Port mirroring on the Rapier 48 and 48i was not operating correctly because
Destination Lookup Failure (DLF) frames were sent from the mirror port.
This issue has been resolved.
PCR: 02095 Module: SWI Network affecting: No
The software routing performance of the Rapier 48 and Rapier 48i has been
enhanced.
PCR: 02101 Module: SWI Network affecting: No
The layer 3 hardware table was not sorted properly when it contained a
very wide range of IP addresses (eg. 10.0.0.1 - 205.33.3.1). This caused a
small number of packets to be routed by software rather than hardware.
This issue has been resolved.
PCR: 02104 Module: TRG Network affecting: No
The periodic and time trigger counts were incrementing by two instead of
one on each update. This issue has been resolved.
PCR: 02105 Module: FFS Network affecting: No
An error occurred when the FLASH write driver was required to write
values that were not long-word aligned and were at the driver’s page
boundary. The driver attempted to write into the next section of memory. It
also attempted to read the status of this section of memory, and
misinterpreted the result as a low Vpp voltage. Also, errors occurred during
FLASH compaction. These issues have been resolved.

inspection of firewall sessions only, and not to the TCP module. Previously,
PCR 01263 reduced the timeout value for sessions placed in the CLOSED
state after a TCP/FIN packet was received.
PCR: 02063 Module: FIREWALL Network affecting: No
Firewall IP access lists were not working correctly. If an IP range was
specified without spaces between the IP address and the separating '-' the
range would be ignored. Spaces are no longer required. Also, matches were
made to addresses covered by a range in an access list if the matching range
was numerically the lowest in the list. This issue has been resolved.

Patch 86222-12 includes all issues resolved and enhancements released in
previous patches for Software Release 2.2.2, and the following enhancements:
PCR: 01223 Module: IPG Network affecting: No
If route filters existed and a RESET IP command was executed, some static
and interface routes were incorrectly removed if the filters matched. This
issue has been resolved.
PCR: 01257 Module: DHCP Network affecting: No
DHCP occasionally caused a fatal error. Also, while an address was in the
reclaiming list, a DHCPDISCOVERY message requesting the address made
the address disappear. These issues have been resolved.
PCR: 01261 Module: IPG/VRRP Network affecting: No
A fatal error occurred when forwarding IP packets with VRRP enabled. This
issue has been resolved.
PCR: 01263 Module: FIREWALL Network affecting: No
The firewall TCP timeout values for sessions in the CLOSED and
TIMEWAIT states have been reduced. This only applies to the stateful
inspection of firewall sessions and not to the TCP module.
PCR: 01268 Module: SWI Network affecting: No
When a Rapier was under heavy load from software routing (e.g. after a
reboot and before the routing tables were refreshed), OSPF could take a long
time to converge. This patch gives OSPF packets higher priority to expedite
OSPF convergence.
PCR: 01269 Module: SWI Network affecting: No
A new feature permits hardware filtering by the Rapier family based on the
Ethernet frame type. The TYPE parameter:

Refinements were made to the switch chip register settings improving CoS
provision with the newer revision of switching silicon on the Rapier 16,
Rapier 24 and Rapier 48.
PCR: 01275 Module: FIREWALL Network affecting: No
The firewall was incorrectly forwarding multicast packets originating from
a private address in cases where a matching route was defined. This issue
has been resolved.
PCR: 01276 Module: SWI Network affecting: No
When the speed of one or more switch ports was forced to a half duplex
setting and the ports were then added to a trunk group configured for full
duplex operation, the port settings were not overridden by the trunk group
speed setting. The trunk group speed setting will now take precedence over
the port speed setting.
PCR: 01287 Module: OSPF Network affecting: No
Configuring IP route filters did not stop flooding of AS external LSAs to
neigbours at startup. The result was that the neigbour received the AS LSAs
and added the corresponding routes into its own routing table. However,
after some time (e.g. 1 hour), the AS external LSAs in the neigbour’s
database disappeared, but the corresponding routes were still in its routing
table. This issue has been resolved.
PCR: 01289 Module: VRRP Network affecting: No
The checksum in VRRP advertisements was not being calculated correctly.
The calculation was not compatible with the RFC. This issue has been
resolved.
PCR: 01290 Module: PPP Network affecting: No
When PPP was running over Ethernet to a client from another vendor, the
Maximum Transmission Unit value for the link was not adjusted from the
PPP default of 1500 to 1492. This issue has been resolved.
PCR: 01291 Module: IPG(IGMP) Network affecting: No
IGMP did not send the Start Up Query, and the Other Querier Present Timer
did not change the Time Out value accordingly if Query Interval was
changed. IGMP did not notify other registered parties (PIM and DVMRP)
when a port was deleted from a membership group. IGMP reported a
membership leave to other parties while it was still waiting for a reply to a
group specific query from a leaving member. These issues have been
resolved.

PCR: 02003 Module: FIREWALL Network affecting: No
The timeout value for ICMP session entries in the firewall can now be
adjusted via the OTHERTIMEOUT parameter of the SET FIRE POLICY
command. Note: if the value for OTHERTIMEOUT is set to more than 10
minutes the timeout used for ICMP sessions will default to 10 minutes.
PCR: 02007 Module: DHCP Network affecting: No
When a DHCP server received a DHCP DISCOVERY packet passed by a
relay agent, requesting an IP address that did not belong to the subnet the
client and the relay agent were attached to, it offered the requested address
if it was available. The DHCP server will now only offer an IP address from
the subnet that connects the client and the relay agent.
PCR: 02008 Module: TRIGGER Network affecting: No
The first periodic after day trigger boundary (i.e. midnight) did not occur.
A range check error occurred due to an incorrect comparison. These issues
have been resolved.

Patch 86222-27 For Rapier Switches 31
PCR: 01242 Module: CORE, SNMP Network affecting: No
The switch now delays sending link traps immediately after a restart to give
the link to the trap host time to come up. A similar change has been made
for the cold start trap. After a 10s delay, all interfaces which are UP have a
link trap generated for them. After that, link traps are sent as normal.
PCR: 01244 Module: SWI, CORE, IPG Network affecting: No
Processing invalid UDP packets caused a memory leak. This issue has been
resolved. Additional debugging facilities were added.
PCR: 01246 Module: SWI Network affecting: No
The default setting for the switch port parameter INFILTERING is now OFF,
as specified in IEEE802.1Q. A VLAN will still reject these packets if they are
not from valid VLAN member ports.
PCR: 01247 Module: IPG Network affecting: No
The IGMP snooping forwarding process now correctly selects outgoing
ports when DVMRP is managing the multicast routing information.
PCR: 01248 Module: SWI Network affecting: No
A configuration problem prevented trunking of gigabit ports at 100Mbit
speeds. This issue has been resolved. The A39 gigabit copper uplink
reverted to autonegotiation after a restart, even if it was configured to a
fixed speed. This issue has been resolved. When the port has been
configured for a fixed speed, the mode is now set to MDIX, not MDI.
PCR: 01254 Module: PRI Network affecting: No
When an M2 version of the AR020 PRI E1/T1 PIC was installed in a AR040
NSM it was not possible to select the T1 mode of operation regardless of the

MIB object triggerLastTriggerActivated ({ enterprises(1) alliedTelesyn(207)
mibObjects(8) brouterMib(4) atrouter(4) modules(4) trigger(53) 1 }) has been
defined, to record the trigger number of the last trigger activated, and this
variable is now transmitted in the trigger activation trap triggerTrap.
PCR: 01214 Module: SWI Network affecting: No
In a Rapier G6, fitted with a fibre uplink module with all ports active,
switching traffic between port 1 and the uplink caused the traffic flow to
cease after a period of time depending on the volume of traffic. This issue
has been resolved.
PCR: 01216 Module: STP Network affecting: No
The Rapier did not include the message age of the received BDPU message
in the message age of the BDPU it transmitted. Also, the message age of the
message transmitted BDPU could be less than that of the received BDPU,
which contravenes IEEE 802.3d. This issue has been resolved.
PCR: 01219 Module: VLAN,SWI Network affecting: No
Reception of incorrectly tagged packets was causing corruption of the ARL

Patch 86222-01 includes the following enhancement for Software Release 2.2.2:
PCR: 01100 Module: DHCP Network affecting: No
The DHCP server identified the wrong port numbers for incoming DHCP
requests causing DHCP replies to be sent to the wrong port. This issued has
been resolved.
PCR: 01102 Module: IPG Network affecting: No
The IP flow cache occasionally generated a watchdog fatal error. This issued
has been resolved.
PCR: 01102 Module: SWI Network affecting: No
Deleting entries from an L3 table occasionally resulted in a watchdog fatal
error. This issue has been resolved.
PCR: 01106 Module: PKI Network affecting: No
PKI enrolment no longer causes message validation to fail.
PCR: 01119 Module: IPV6 Network affecting: No
Repeated addition and deletion of an address with the VALID parameter set
to or from an IPV6 interface caused a fatal error. This issue has been
corrected. The VALID parameter specifies the life of the address, and
defaults to INFINITE. The address is deleted when the lifetime expires. The
PREF parameter specifies the time that the address is the preferred address
of the interface, and defaults to INFINITE. PREF must be less than or equal
to VALID. IPV6 now checks and ensures that if either PREF or VALID is
specified, PREF is less than or equal to VALID. When an address is deleted
the timers are now correctly cleared.
PCR: 01120 Module: IPG Network affecting: No
IP sometimes passed the wrong port number to PIM, causing PIM to
process the wrong port number in its routing table. This issued has been
resolved.

Enable and Disable ICMP Messages
The Internet Control Message Protocol (ICMP) allows routers to send error and
control messages to other routers or hosts. It provides the communication
between IP software on one system and IP software on another.
This enhancement allows the switch to enable or disable some ICMP messages
when directed by the network manager.
The ICMP messages that are able to be enabled or disabled are:
■ Network unreachable (RFC792 Type 3 Code 0)
■ Host unreachable (RFC792 Type 3 Code 1)
■ ICMP redirect messages (RFC792 Type 5 Code 0, 1, 2, 3)
Network Unreachable
This message indicates that the switch does not know how to reach the
destination network.
Host Unreachable
This message indicates that the switch does not know how to reach the host.
ICMP Redirect
This message is sent to a local host to tell it that its target is located on the same
LAN (no routing is required) or when it detects a host using a non-optimal route
(usually because a link has failed or changed its status)
router to advise of a better route to a particular destination.
For more information on ICMP, see the IP Chapter in your switch’s Software
Reference manual.

Commands
This enhancement introduces three new commands:
■ DISABLE IP ICMPREPLY
■ ENABLE IP ICMPREPLY
■ SHOW IP ICMPREPLY
DISABLE IP ICMPREPLY
Syntax DISABLE IP
ICMPREPLY[={ALL|NETUNREACH|HOSTUNREACH|REDIRECT}]
Description This command disables ICMP reply messages.

Parameter Meaning
ICMP Reply Messages A list of ICMP configurable reply messages and whether
they are enabled or disabled.
IGMP Snooping All-Group Entry
Because IGMP is an IP-based protocol, multicast group membership for VLAN
aware devices is on a per-VLAN basis. If at least one port in the VLAN is a
member of a multicast group, multicast packets will be flooded onto all ports in
the VLAN by default.
IGMP snooping enables the switch to forward multicast traffic intelligently on
the switch. The switch listens to IGMP membership reports, queries and leaves
messages to identify the switch ports that are members of multicast groups.
Multicast traffic will only be forwarded to ports identified as members of the
specific multicast group.
This enhancement allows network managers to prevent specified ports from
acting as IGMP all-group ports, and specify which ports are allowed to behave
as all-group entry ports, by using the ENABLE IP IGMP ALLGROUP
command.
For example, consider a video streaming service which has 15 channels. When
the switch receives IGMP membership reports destined for the address
239.0.0.2 from an unauthorised user, all 15 channels of multicast data floods to
that port, which may affect the service of the network. In order to avoid this,
the network manager decides whether or not to allow a particular port to
behave as an IGMP all-group port, e.g. port 8. Then, whenever the above IGMP
membership report is sent, the switch will not automatically add port 8 as one
of the egress ports for any IGMP membership report group, so video streaming
will not get forwarded to disabled all-group ports selected by the network
manager.
Commands
This enhancement modifies one command:
■ SHOW IP IGMP
and has two new commands:
■ ENABLE IP IGMP ALLGROUP
■ DISABLE IP IGMP ALLGROUP

New Commands
This enhancement request introduces two new commands from enabling/
disabling all-group entries on switch ports.
ENABLE IP IGMP ALLGROUP
Syntax ENABLE IP IGMP ALLGROUP=[{port-list|ALL}]
where:
■ port-list is a port number, a range of port numbers (specified as n-m), or a
comma separated list of port numbers and/or ranges. Port numbers start
at 1 ad end at m, where m is the highest numbered Ethernet switch port,
including uplink ports.
Description This command enables the specified port(s) to behave as a multicast all-group
ports.
The ALLGROUP parameter specifies the list of ports able to behave as allgroup entry ports. If ALL is specified, all ports are able to behave as all-group
entry ports. The default is ALL.
Examples To enable ports 1, 5 and 7 to behave as all-group entry ports, use the command:
ENABLE IP IGMP ALLGROUP=1,5,7
See Also DISABLE IP IGMP ALLGROUP
SHOW IP IGMP
DISABLE IP IGMP ALLGROUP
Syntax DISABLE IP IGMP ALLGROUP=[{port-list|ALL}]
where:
■ port-list is a port number, a range of port numbers (specified as n-m), or a
comma separated list of port numbers and/or ranges. Port numbers start
at 1 and end at m, where m is the highest numbered Ethernet switch port,
including uplink ports.
Description This command disables the specified port(s) from acting as a multicast all-
group entry ports. Ports that are disabled have a “#” symbol next to the port
number in the output of the SHOW IP IGMP command.
Examples To prevent ports 1, 5 and 7 from behaving as all-group entry ports, use the
command:
DISABLE IP IGMP ALLGROUP=1,5,7
See Also ENABLE IP IGMP ALLGROUP
