Patch 86222-09includes all issues resolved and enhancements released in previous patches for Software Release 2.2.2, and the following enhancements:

PCR: 01189

Module: STP, SWI

Network affecting: Yes

A new feature, STP forwarding, has been added. STP forwarding can be enabled and disabled using the commands:

ENABLE SWI STPFORWARD

DISABLE SWI STPFORWARD

When STP forwarding is enabled, all STP forwarding is ignored and all

BDPUs received on a port are forwarded on all other ports.

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.

3

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 jumper setting. This issue has been resolved.

PCR: 01256

Module: Firewall

Network affecting: No

A fatal error occurred when the firewall discarded disallowed multicast packets. This issue has been resolved.

Patch 86222-08includes all issues resolved and enhancements released in previous patches for Software Release 2.2.2, and the following enhancements:

PCR: 01201

Module: L2TP

Network affecting: Yes

Tunnel creation failed when attempting to establish a point-to-pointtunnel from an ATR router (tunnel originator) to another vendor’s router. This issue has been resolved.

PCR: 01233

Module: PIM

Network affecting: No

When IGMP snooping was enabled, if a member left a group on a port, it could not re-jointhe group on that port. This issue has been resolved.

Substantial changes have been made to PIM in more recent code releases. These have been retrofitted to 2-2-2in the patch. Note: these changes have incorporated PCRs 01159 and 01190.

PCR: 01236

Module: PPP

Network affecting: No

The PPPoE access concentrator did not stop RADIUS accounting when a PADT termination was received without receiving a proper PPP termination first. This issue has been resolved.

Patch 86222-07includes all issues resolved and enhancements released in previous patches for Software Release 2.2.2, and the following enhancements:

PCR: 01018 Module: DHCP

Network affecting: No

DHCP now correctly handles request messages containing request list options not supported by the router.

PCR: 01160

Module: IPG,FIREWALL

Network affecting: No

The router would accept TCP sessions with destination address the same as the subnet broadcast address for one of the router’s interfaces. Firewallgenerated packets destined for a subnet broadcast address on one of the routers interfaces would cause a fatal error. These issues have been resolved.

PCR: 01168

Module: HTTP

Network affecting: No

A watchdog timout occurred when the router received an HTTP message with an over-lengthheader. Normal HTTP requests would also occasionally cause watchdog timeouts. These issues have been resolved.

PCR: 01182

Module: OSPF

Network affecting: No

The OSPF route filter was not filtering out external routes. This issue has been resolved.

PCR: 01193

Module: IPG

Network affecting: No

MD5 Authentication now works correctly with RIP packets.

PCR: 01194

Module: L2TP, IPG

Network affecting: No

The SET IP LOCAL command caused a fatal error if the router was configured with a default route over an L2TP tunnel, because there was no valid route to the remote IP address of the tunnel. This issue has been resolved.

PCR: 01197

Module: Q931

Network affecting: No

Debug messages are no longer generated when a Q.931 Advise of Charge

Notification message is received.

 

PCR: 01198

Module: TCP

Network affecting: No

TCP sessions would get stuck in the FINWAIT2 state if the remote host did not send a FIN message when required. The router now starts a timer when a TCP session enters the FINWAIT2 state and will automatically close the session if the timer expires.

PCR: 01199 Module: IPG Network affecting: No

The SET IP FILTER command was not correctly handling the ICMPTYPE and ICMPCODE parameters. This issue has been resolved.

PCR: 01202 Module: DHCP Network affecting: No

The router will now accept DHCP messages that are greater than or equal to 576 bytes in size, and reject any message smaller than 576 bytes. This operation conforms to RFC 1541.

PCR: 01203 Module: ISAKMP Network affecting: No

ISAKMP quick mode exchanges are now committed if any traffic is received over the newly generated SA. This improves stability in very lossy networks where the commit message may get lost.

PCR: 01204 Module: ISAKMP Network affecting: No

ISAKMP debugging caused a fatal error when the debugging mode was set to ALL and PFS was enabled. This issue has been resolved.

PCR: 01205 Module: PPP Network affecting: No

PPPoE interfaces with IDLE set to ON would not retry active discovery when more data was received if active discovery had previously failed. This issue has been resolved.

PCR: 01206

Module: ISAKMP

Network affecting: No

A memory loss occurred when certificates were used by ISAKMP. This issue

has been resolved.

 

PCR: 01207

Module: ISAKMP

Network affecting: No

ISAKMP heartbeats are no longer transmitted if the lower layer interface is down. This stops ISAKMP heartbeats from bringing up links in dial-upenvironments.

PCR: 01209 Module: ISAKMP Network affecting: No

In some conditions it was possible for ISAKMP packets to be lost and not retransmitted. Incoming ISAKMP messages are now validated before stopping retransmission of the previous message.

PCR: 01211 Module: SWI Network affecting: No

The COS_DST bit on ARL for L3 interface should be 0x4 (higher priority) for

CPU ports. This has been corrected.

Patch Release Note

PCR: 01213

Module: TRG, SNMP

Network affecting: No

The Trigger Facility was generating a trap with variable { 0 0 }, and was not documented in the ATI enterprise MIB. This issue has been resolved. 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 traptriggerTrap.

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 table, eventually causing the switch to lock up. This issue has been resolved. Tagged packets with invalid VLAN identifiers are now discarded. The INFILTERING parameter of the SET SWITCH PORT command now defaults to ON.

PCR: 01221

Module: SWI

Network affecting: No

Flow control performance has been improved.

 

PCR: 01225

Module: IPSEC

Network affecting: No

The IPsec SA ID now wraps correctly at the 16 bit (ID = 65535) boundary.

The ID is also checked to verify that it is free before it is used.

PCR: 01227

Module: PPP

Network affecting: No

If PPPoE AC services were not deleted in the same order they were added, the DELETE command would return an “ operation successful” message but the service would still appear in the output of the SHOW PPP PPPOE command. This issued has been resolved.

PCR: 01229

Module: SWI

Network affecting: No

The CREATE CONFIG command did not include all required L3FILTER parameters in the generated script file.

PCR: 01232

Module: SWI

Network affecting: No

The L3 table on the Rapier G6 is now cleared when a switch port goes down to ensure the L3 and ARP tables are consistent.
