Features in 89275-02
Maintenance release 89275-02 includes the following enhancements and
resolved issues:
Level 1
No level one issues.
Level 2
CR00008262 Module: OSPFv2 Level:2
Modifying the deadInterval, helloInterval, pollinterval, transitDelay,
rxmtinterval, authentication, password, or boost1 parameters of the SET
OSPF INTERFACE command used to caused the router to drop neighbour
adjacencies. These parameters now can be modified without dropping the
neighbour relationships.
Modifying the stubmetric and authentication of SET OSPF AREA command
caused the router to drop the neighbour adjacencies on the area. These
parameters now can be modified without dropping the neighbour
relationships.
Modifying the effect of the SET OSPF RANGE command used to caused the
router to drop the neighbour adjacencies on all the interfaces of the range.
This parameter now can be modified without dropping the neighbour
relationships.
Version 89275-02 for Software Release 2.7.5
C613-10458-00 REV A
Version 89275-02 for AT-8900 and AT-9900 series switches 3
CR00008325 Module: USER Level: 2
If users were defined on a RADIUS server for the purpose of 802.1x or
firewall authentication, then these users were also given console login
rights with user privilege. The default behaviour has been changed so that
console login is only authorised through explicitly setting the service-type
attribute of the RADIUS record to Login (for User Privilege), NAS prompt
(for Manager privilege), or Administrative (for security officer privilege).
CR00008329 Module: STP Level: 2
If ports that were members of a trunk group were also members of multiple
VLANs, and those VLANs were spread across more than one STP instance,
the STP states of the ports were not always being set correctly.
CR00008391 Module: NAT Level: 2
An issue existed in IP NAT when creating a new session for a packet
destined for an IP address that had been dynamically allocated to a private
IP address. The session created would NAT the destination address to the
source address of the packet instead of the private IP address.
This issue has been resolved.
CR00008691 Module: DHCP4 Level: 2
Previously, a DHCP received by the server from a client which it should
have had no knowledge about was acted on by that server and a NAK was
sent to the client. This interfered with any responses from the actual server
which was responsible for this client. This delayed the time it took the client
to establish an IP address from the correct server. This is now corrected and
the server now behaves in a manner which is compliant with the RFC,
resulting in faster establishment of an IP address using DHCP under these
conditions.
CR00008737 Module: OSPFv2 Level: 2
When the router was acting as an NSSA ASBR it was not setting the
forwarding address in Type 7 LS update, therefore Type 7 LSAs were not
being translated.
This issue has been resolved.
CR00009236 Module: BGPv4 Level: 2
BGP distribution of routes to another peer when learnt from a peer was very
slow.
This issue has been resolved.
CR00009242 Module: LACP Level: 2
Version 89275-02 for Software Release 2.7.5
C613-10458-00 REV A
Some enhancements have been made so that:
1.When any of the ports in a trunk group is disconnected, there will be no
momentary communication interruption.
2.When the second last LACP trunk port is disconnected, there will be no
momentary communication interruption.
3.An issue has been resolved where LACP was randomly setting the switch
port to STP BLOCK.
4 Software Maintenance Release Note
CR00009313 Module: PORT AUTH Level: 2
When a switch port was disabled using the DISABLE SWITCH PORT
command, the MAC address of the authorised supplicant on the port
remained in the FDB table. The supplicant's MAC address is now removed
when the port is disabled. This has been resolved on both single- and multisupplicant mode.
When portauth was disabled by using the DISABLE PORTAUTH
command, the supplicant MAC address in the switch filter was not
removed. This has been resolved and all MAC addresses added by portauth
internally are deleted when the supplicant is removed or unauthorised.
Also the same behaviour in PURGE PORTAUTH PORT, SET PORTAUTH
PORT DEFAULT, DISABLE PORTAUTH PORT and RESET PORTAUTH
PORTMULTIMIB commands has been fixed in both 802.1x and MAC-based
port authentication.
CR00009331 Module: OSPF Level: 2
Previously, the command SET IP ROUTE PREFERENCE would reset the
OSPF neighbour connection, now this reset is no longer required.
This issue has been resolved.
CR00009361 Module: IPv4 Level: 2
If the router received a stream of IPv4-encapsulated IPv6 packets, a memory
leak could occur if no IPv6-over-IPv4 tunnel was configured.
This issue has been resolved.
CR00009405 Module: BGP4 Level: 2
Previously, when BGP recorded a BGP peer route with nexthop = 0 (a rare
case), it would enter it into its next hop list table but then would fail next
time it checked the integrity of the data on this list while reviewing the list
after a link state change.
This issue has been resolved.
CR00009409 Module: SWITCH Level: 2
In rare circumstances it was possible for the SFP LEDs to apparently freeze.
This issue has been resolved.
CR00009421 Module: QoS Level: 2
When the command SET QOS was issued with parameters to set multiple
flow groups to the same action rule, the switch would reboot.
When the command SET QOS was issued for multiple traffic classes to the
same action, the switch would reboot.
These issues have been resolved.
