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:
Broadcast Storm rate limiting was not limiting broadcast packets when
these were set per-VLAN. This issue has been resolved.
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.
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.
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.
Rapid STP was not interacting correctly with trunk groups. This issue has
been resolved.
Level 1 This issue will cause significant interruption to network services, and
there is no work-around.
Level 2 This issue will cause interruption to network service, however there
is a work-around.
Level 3 This issue will seldom appear, and will cause minor inconvenience.
Level 4 This issue represents a cosmetic change and does not affect network
operation.
