All ports on a ring adapter card or module are possible congestion points and therefore can have network queue QoS policies applied to them.
In the bridging domain, a single ring type network QoS policy can be applied at the adapter card level and operates on the ring ports and the add/drop port. In the IP domain, IP interface type network QoS policies can be applied to router interfaces.
Network QoS policies are created using the config>qos>network command, which includes the network-policy-type keyword to specify the type of policy:
ring (for bridging domain policies)
ip-interface (for network ingress and network egress IP domain policies)
default (for setting the policy to policy 1, the system default policy)
Once the policy has been created, its default action and classification mapping can be configured.
