Corrected Problems
in Release 3.0.5

Bridging

The 36-port 10/100BASE-TX Layer 2 modules (Model Numbers
3CB9LF36R and 3CB9LF36T) now correctly populate the address table
®
for Transcend Address Tracker. (26575)
Transcend Address Tracker polling no longer causes STP convergence.
(26879)
Removing the default VLAN before you create additional VLANs no
longer causes modules to go down after a module reset. Previously,
you had to move the module to another slot in the chassis to
reinitialize. (26223)
Previously, in some configurations, the system did not allow the proper
number of VLANs to be defined, causing an out-of-resources
message. The maximum number of VLANS are now allowed on
regular switching modules, but not on the fabric. (27137)
This section describes problems that have been corrected for Layer 2
Switching Modules operating with software Release 3.0.5.
If you want addresses to age more quickly after a link down event, you
can now enable the
spanningTree stpState
Spanning Tree Protocol (STP); rather, it uses one of the STP values to
temporarily age addresses more quickly after link down events.
Prior to Release 3.0.5, if you did not have STP enabled, a Layer 2
module would not flush MAC addresses after a link down event; it
would only age addresses according to the value set in
. This situation can cause VLAN-assignment problems when
agingTime
endstations are frequently plugged and unplugged into ports on the
module and the Transcend Enterprise VLAN Manager (EVM)
application is used on the network. That is, if a new endstation (with a
new MAC address) is plugged into a port prior to the aging out of the
old MAC address on that port, EVM may assign the endstation to the
VLAN to which the old MAC address belonged, which could be an
incorrect VLAN for the new endstation. Now, with the
option, this problem is resolved. For more information about the
option, see the "Release Highlights" chapter of these
agingOnly
release notes. (28875, 30198, 29697)
