Configuring QoS
Configuration Examples for Policy Maps
Switch(config-if-range)# exit
These steps activate all applicable Ethernet ports:
Switch(config)# interface range GigabitEthernet1/17-18
Switch(config-if-range)# no shutdown
Switch(config-if-range)# exit
You should use the same procedure when adding a class to an attached output service policy.
Note: Problems can occur if you do not follow the previous sequence.
When a policy map is attached to an interface, all traffic that does not explicitly match the configured class maps within
the policy map should go through the default queue (class class-default). However, in some cases, traffic that does not
explicitly match the output policy-map classes could go through more than one queue. This queuing problem can occur
when you do not follow the previous procedure and do not attach an output policy to all active ports.
