Tag Switching 9-17
Configuration Criteria
Configuration Criteria
Tag switching for VSIs on a BXM card is configured using the cnfrsrc and cnfqbin commands.
Qbin 10 is assigned to tag switching.
The cnfqbin Command
The cnfqbin command is used to adjust the threshold for the traffic arriving in Qbin 10 of a given
VSI interface as away of fine tuning traffic delay.
If the cnfqbin command is used to set an existing Qbin to disabled, the egress of the connection
traffic to the network is disabled. Re-enabling the Qbin restores the egress traffic.
The cnfrsrc Command
The cnfrsrc command is used to enable a VSI partition and to allocate resources to the partition. An
example of a cnfrsrc command is shown in the following example. If the cnfrsrc command is used
to disable a partition, those connections are deleted.
