Known Problems
This section describes problems that are known to exist in Layer 2 
switching module operational software Release 3.0.
The numbers that appear in parentheses at the end of some descriptions 
are for internal 3Com use only.
System
At the Administration Console, entering a seemingly valid command 
string (two or more commands taken from menus and nested 
submenus) may not work. If this situation occurs, enter commands 
separately from one menu prompt at a time.
Some Release 3.0.x features may become unstable when the 
associated switch devices are polled by Enterprise VLAN Manager, 
Address Tracker, and other Transcend applications that poll the bridge 
address MIB tables. These features and protocols include Trunk 
Control Message Protocol (TCMP) and Spanning Tree Protocol (STP) 
topology changes.
3Com recommends that you use these Transcend management 
applications only for configuration and problem isolation purposes. 
When you use these applications, SNMP polling can contribute to 
unexpected events in the configuration associated with TCMP and 
STP. (29371 and 29797)
For information about controlling the Transcend Enterprise VLAN 
Manager and Address Tracker management applications, see the 
“General Functional Limitations” section, problem NMDww04250, in the 
Transcend Network Control Services Readme files for the February 2000 
Update.
Management
When you are prompted to “wait” for a reset to take place, do not 
attempt to start a new connection during this delay. Wait until control 
returns you to the Administration Console prompt before you start a 
new connection.
After you enter an 
nvdata reset 
command (or initiate a trunk group 
definition or deletion), there is a delay before the module resets.The 
following MIB-II counters do not increment:
inReceives
tcpOutRsts
udpOutDatagrams
udpNoPorts
