Trunking
■
Do not use special characters in trunk names. (25715)

The Administration Console of the 36-port 10/100BASE-TX Fast
Ethernet RJ-45 Layer 2 Switching Module (Model Number 3CB9LF36R)
incorrectly allows you to add a roving analysis port when that port has
already been defined as part of a trunk group. When you do this, the
system removes the analyzer port from all VLANs.
To recover from this situation, you must remove the roving analysis
port with the
analyzer remove
command and modify the affected
VLANs to add the trunk port back to the VLAN with the
bridge vlan
modify
command. (29802)
■
These TCMP trunk statistics in the
bridge trunk detail
display are
not reset after you enter the
module baseline set
command:
■
rxFrames, rxHellos, txFrames, txHellos, rxBadVersion, rxBadType,
rxSameTrunkId, rxOverflow
■
If a trunk is configured on a module, the following fields in the
ethernet detail
display may show rates that are higher than the
actual rates:
■
rxFrameRate, rxByteRate, rxPeakFrameRate, rxPeakByteRate,
txFrameRate, txByteRate, txPeakFrameRate, txPeakByteRate
In addition, the port for which the report is requested does not have
to be involved in the trunk for this situation to occur.
■
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.
