This section describes problems that relate to Layer 2 Switching Modules
and that were corrected in software Release 3.0.0.
The system no longer displays
chassis and during the system start-up procedures. (27650 and
29672)
The 36-port 10/100BASE-TX Layer 2 modules (Model Numbers
3CB9LF36R and 3CB9LF36T) no longer experience port lockup due to
high port errors. (28668)
Uploading a configuration file that already exists on the EME to a TFTP
server no longer removes the file from the EME file system, as shown
in the
show file
The 36-port 10/100BASE-TX Layer 2 Fast Ethernet RJ-45 module
(Model Number 3CB9LF36R) no longer asserts because of port duplex
mode mismatch and TX underrun errors. (27365, 27362, and 29195)
Current autonegotiation status is now correctly reflected the first time
that you view the Ethernet summary and detail displays. (27864)
Whenever a non-switch fabric module is reset (with the
module nvData reset
chassis, by doing a warm reset, by running service diagnostics, and so
forth) or a backplane port is disabled and then reenabled, the links to
the switch fabric module no longer go down on some occasions and
are now always reestablished. (30063)
You can now list the bridge port address table and walk through MIBs
without causing Trunk Control Message Protocol (TCMP)-enabled
trunk ports to go down, or causing Spanning Tree Protocol (STP)
topology changes. (23076 and 24547)
When a port enters the Spanning Tree forwarding state, the root
bridge no longer erroneously sends a new root trap instead of a
topology change trap. (28665)
Enabling the Spanning Tree Protocol (STP) on a port that already had
STP enabled no longer results in an erroneous Spanning Tree topology
change trap. (28655)
