Features in SB251-10

Patch SB251-10 includes all issues resolved and enhancements released in previous patches for Software Release 2.5.1, and the following enhancements:

PCR: 03335

Module: SWI

Level: 2

Broadcast Storm rate limiting was not limiting broadcast packets when these were set per-VLAN. This issue has been resolved.

PCR: 03399

Module: STP

Level: 4

Enabling STP debug on a SwitchBlade led to invalid port numbers being displayed in the debug output. This issue has been resolved so that ports are correctly displayed in the board.portnumber format.

PCR: 03428

Module: STP

Level: 2

Sometimes while in Rapid STP mode, a port changing its role from

Alternate to Designated or Root did not make a rapid transition to the

Forwarding state. This issue has been resolved.

PCR: 03608

Module: SWI, STP

Level: 3

The DISABLE SWITCH PORT and ENABLE SWITCH PORT commands were not interacting correctly with trunk groups. This issue has been resolved so that if a port in a trunk group is disabled with the DISABLE SWITCH PORT command, the port will now be removed from its trunk group in the hardware tables. Also, enabling a disabled trunk group port now returns the port to its trunk group in the hardware tables.

PCR: 03612

Module: SWI, STP

Level: 2

Rapid STP was not interacting correctly with trunk groups. This issue has been resolved.
