4 Patch Release Note
Patch SB251-10 for Software Release 2.5.1
C613-10361-00 REV J
Features in SB251-08
Patch file details are listed in Table 3:
Patch SB251-08 includes all issues resolved and enhancements released in
previous patches for Software Release 2.5.1, and the following enhancements:
A fatal error occurred when the ADD SWITCH TRUNK command specified
an invalid port. This issue has been resolved.
A fatal error occurred when removing a line card from a SwitchBlade if STP
was enabled. This issue has been resolved.
System performance was low when adding large numbers of entries to
CAM. This issue has been resolved. CAM is now initialised to allow better
performance, especially for the addition of ARP and IP entries.
The DELETE SWITCH TRUNK PORT command could cause an unrelated
port to stop forwarding packets, or learn new MAC addresses. This issue
has been resolved so that unrelated ports are not affected by the trunk group
port deletion.
All IP routes were being added to all switch instances. This caused issues on
SwitchBlade line cards that did not have enough CAM to store the routes,
and the line card did not always need every route. IP routes are now only
added:
• to a switch instance if the route was learned on that instance
• if the route is for an interface
• if the route was added statically, or
• if the switch instance has a CAM which is the same size or larger than
the CAM of the switch instance that the route was learned on.
An issue exists where the CAM entry 0 in the VLAN Tag table is either not
updated or is being overwritten with invalid data. This PCR adds
debugging to trace the fault.
