PR Level Title Description
22321 2 MSTP BPDU gets
corrupted when changing
priority
BPDU gets corrupted when changing priority on
MSTI root bridge (in this case, on alternate
bounday-switch for MST 1). Also, the Regional
Root Bridge ID MAC Address gets corrupted.
22320 1 MSTP may not prevent
loops in certain network
topologies.
When MSTP is used in a network that includes a
switch that is not part of the MSTP region but is part
of the CIST spanning tree, topology changes within
the MSTP region do not converge correctly and
loops occur.
22318 3 Invalid data generated for
SHOW STP INSTANCE
when running MSTP.
In some MSTP network topologies, inconsistent
data is displayed. Destination Root-costs on some
interfaces are not valid. Also, some Designated Root
ID MAC and Designated Bridge MAC addresses are
incorrect.
22316 3 MSTP instance bridge-
priority saved incorrectly
in text config
The bytes in the 16-bit bridge-priority are swapped.
So, for example, the value of PRIORITY=2 is
incorrectly output in the text config as
PRIORITY=512. The workaround is to edit the
value in the text config after generation.
22314 3 MSTP Master Port role
does not return after
topology change
The role for regional root port on "Primary
boundary-switch" changes from Master to
Designated (Forwarding) after any topology change
in the MST and requires "RESET STP" command to
get the Master role to return. This appears to be a
cosmetic problem for the SHOW STP INSTANCE
command.
22296 2 SNMP Access to IGMP
MIB may leak memory
In some circumstances, queries to the IGMP MIB
will leak memory. This can occur, for example, in a
MIB walk through these OIDs.
22292 2 xSTP blocks LAG ports
after swap of activity
In some circumstances, xSTP will incorrectly block
LAG ports after a swap of activity.
