Known Problems in 

Release 3.0.5

This section describes problems that are known to exist in Layer 2 

Switching Modules operating with software Release 3.0.5.

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, 

snmplnASNParseErrs, snmplnBadVersion, 

snmplnBadCommunityNames, snmplnBadCommunityUses
