Procedure
Step 1
Step 2
Step 3
Step 4
This example shows how to enable LLC on an interface:
switch# configure terminal
switch(config)# interface ethernet 1/2
switch(config-if)# flowcontrol receive on transmit on
Verifying QoS Configuration
To verify QoS configuration information, perform one of these tasks:
Command
switch# show class-map
switch# show policy-map [name]
switch# show policy-map interface [interface
number]
switch# show policy-map system
switch# show policy-map type {network-qos | qos
| queuing} [name]
switch# show queuing interface [interface number]
You can clear the QoS policy statistics.
Command
switch# clear qos statistics
