Operating Considerations for Release 3.0.5 59
These control addresses are included in the bridge display address
count field, but are not listed in the bridge port address list.
Trunking
■
When moving a staged module, the trunking configuration is learned
from the fabric when automapping is used. (27113)
■
Make trunking definitions and modifications only from the
Administration Console command line interface, and not through
SNMP.
■
When you add ports to an existing trunk, and change the port mode
in the same modify operation, you need to reset the module and
modify the trunk twice to add the additional ports to the trunk. The
port mode is updated after the first reset operation. You can add a
port to a trunk without changing the port mode in a single modify
operation. (29804)
■
3Com recommends that you enable the Trunk Control Message
Protocol (TCMP) on each end station of a trunk. If this protocol is not
enabled on both end stations, TCMP cannot correctly validate trunk
configuration rules. (29581)
VLANs
■
The maximum number of virtual LANs (VLANs) that you can define in
a Switch 4007 system is 127. You may not be able to add every bridge
port in the system to every VLAN that you have defined.
■
When the
vlan remove all
command is executing, it may take
several minutes to remove all VLANs when the system is operating in
allClosed mode.
