78 ExtremeWare 7.3.1b3 Release Notes
Clarifications, Known Behaviors, and Resolved Issues
Do Not Configure Port Mirroring While Port is Down
If you reconfigure port mirroring while the physical port is down, switched traffic that crosses a routing
boundary is duplicated (PD2-147476551).
ELSM
Spurious Error Message with ELSM
Disabling or enabling ELSM or the ELSM auto-restart port feature might generate an error message
similar to the following:
hfoCliEvent: Command does not support Hitless Failover
You can safely ignore these messages (PD2-182478105).
Spanning Tree
Adding or Deleting a Port from a VLAN Flushes FDB on All STP Protected VLANs
Adding or deleting a port from a VLAN flushes FDB on all STP protected VLANs, which causes the
flow redirect rules with ping tracking configured to also go down (PD2-245992601).
show vlan STP Output is not Correct
The output for the show vlan command does not mark the flag as “T“ (member of the STP domain)
when the VLAN has no ports associated with it. Because the VLAN has no associated ports, it is not
shown as part of the STP domain (PD2-246881901).
STP Topology Change in One STP Domain (S1) Flushes FDB in Other STP Domain (S2)
When two STP instances (S1 and S2) in dot1w mode share the same physical ports, that is, the physical
port is part of both domains, then a topology change in one STP domain (S1) will flush the FDB learned
in the other STP domains (PD2-145439733).
STP CPU Utility Usage Increases and Drops Ping Packets
The STP task CPU utility increases up to 20% and drops ping packets when adding/deleting a port
from the VLAN. Disabling or enabling ports, or adding a tagged port to the VLAN does not affect
switch performance. A workaround is to enable STP on ports that have STP disabled (PD2-236187221,
PD2-239254001).
Disabling ignore-bpdu Adds CPU MAC Entry to FDB
If you disable ignore-bpdu, an entry for the CPU MAC is added to the FDB for the VLAN
(PD2-225957431).
Enabling STP on MAC-based VLANs Might Cause Connectivity Loss
On a BlackDiamond, if you enable STP on a MAC-based VLAN, you might experience a loss of
connectivity (PD2-223958706).
