12 Patch Release Note
Patch SB251-13 for Software Release 2.5.1
C613-10361-00 REV M
Prefixes of Anycast addresses could not be shared on the same port. This
issue has been resolved.
On an AT-9800 with certain third party GBICs, running the restart reboot
command would cause the switch to lock-up. However the problem did not
occur when using the Reset button. This issue has been resolved by
disabling all ports before performing a RESTART REBOOT.
IPv6 was using the same SA (security association) soft expiry timer at both
ends of link. This was wasting CPU and memory resources. This issue has
been resolved.
A multicast listener discovery (MLD) snooping entry was incorrectly added
to the SwitchBlade’s layer two multicast address table.
The AT-9800 was not adding layer two MLD Snooping when additional
VLANs were created.
The failure of a SwitchBlade port was causing restarts due to the switch
attempting to remove the port from a “non existent” MLD Snooping list.
These three issues have been resolved.
Large routing areas, containing many hosts and interfaces, were causing
fatal errors due to the excessive number of link state advertisements
generated. This issue has been resolved by limiting the combined number
of routers and hosts within each area to 100.
The IP option field for trace route was not being filled correctly when equal
cost multipath routes were used. This has now been fixed.
Route flapping was occurring when an interface went down and there was
another path to the next hop. This issue has been resolved.
A fatal error would occur if a file whose name contained Japanese
characters was deleted from compact flash. This issue has been resolved.
In configurations containing many VLANs, temporary lockups were
frequently occurring while the hardware tables were being updated. This
patch substantially reduces the severity of these lockups.
Running the SHOW IP IGMP COUNTER command was displaying zero
values for the outQuery and outTotal counters. This issue has been resolved.
