42 ExtremeWare 7.1.1 Release Notes
Clarifications, Known Behaviors, and Resolved Issues
Configure Fewer than 4,000 VLANs in an STPD
If you add more than 4,000 VLANs to an STP domain, the switch might run out of memory
(PD2-135842818).
The show stpd ports Output Incorrect After Topology Change
Occasionally, after an 802.1w topology change, the flag in the output of the show stpd ports
command still displays
TC (PD2-115121007).
802.1w and IGMP Snooping
If you are using 802.1w and IGMP snooping, an 802.1w topology change can interrupt the multicast
stream for up to 125 seconds by default (PD2-118511373).
Output of show stpName port detail Command in Hex Format
The output of the show stpName port detail command displays the PortID in hex format instead of
decimal format. If you do not specify the
detail parameter, the output correctly displays in decimal
format (PD2-136044001).
Do Not Re-use VLAN Tags
When you delete a VLAN, the tag is not deleted from the STP domain. If you create a new VLAN with
the same tag, you cannot add that VLAN to a different STP domain. You must either add the VLAN to
the STP domain associated with the tag, or delete the STP domain associated with the tag, create a new
STP domain, and add the VLAN to new STP domain. To avoid this, do not use the same tag
(PD2-137137230).
Ensure that a VLAN Contains Active Ports
Before you add a VLAN to an STP domain, ensure that the VLAN contains active ports. Otherwise you
must disable STP, remove the VLAN from the STP domain, add the ports to the VLAN, add the VLAN
to the STP domain, and enable STP (PD2-137137236).
If You Delete a Port from the STPD, You Cannot Add It Through a VLAN
If you delete a port from the STPD, then add a VLAN containing that port to the STPD, the deleted port
is not added. To work around this, add the port back to the STPD (PD2-144382901).
The unconfigure stp Command Does Not Clear All Configurations
The unconfigure stpd command does not clear the tag, VLAN, operational mode, rapid root failover,
port mode, or port link-type. To clear these configurations, use the
delete stpd command
(PD2-137310575).
Enabling ignore-bpdu or ignore-stp
If you enable ignore-bpdu or ignore-stp on a VLAN and then enable STP, the switch still participates in
STP election. To work around this, reboot the switch (PD2-140533593).
