Do not enter the
bridge port flush all
command on any
switching module when there are more than 1000 MAC addresses in
its bridge address table.
Trunking
■
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)
■
Each module is allowed a certain number of member ports in a trunk
(L2=6 and L3=8). When you modify a trunk so that the sum of the
existing ports plus the added ports is greater than the number of ports
allowed, an error is generated which states that the internal resource
threshold has been exceeded and the ports have not been added to
the trunk. To workaround this, do not modify a trunk so that the sum
of the existing trunk member ports and the added ports are greater
than 6 on Layer 2 modules and greater than 8 on Multilayer modules.
Instead, perform a modification to remove the old ports, and then
another modification to add the new ports. This involves the module
rebooting twice. (30638)
■
On a CoreBuilder 9000 with a single switch fabric module installed,
when you insert a switching module that supports trunks on the
backplane into an unpopulated slot that has autoMap enabled, only
the first link of the trunk for that slot is in the
Up state, and other links
are in the Down state.
There are two ways to avoid this problem:
■
Do not enable autoMap on an unpopulated slot. Enable autoMap
after you insert the switching module.
■
Enable all backplane links in that slot that are in the Down state.
