Quality of Service Guide QoS and QoS Policies
Edition: 01 3HE 11014 AAAC TQZZA 67
To manage add/drop traffic classification and remarking in the L3 IP domain,
ip-interface type network QoS policies can be configured for router interfaces on the
v-port. To manage add/drop traffic queuing and scheduling in the L3 IP domain,
network queue QoS policies can be configured for the v-port and at network ingress
at the adapter card level (under the config>card>mda context).

3.1.12.1 Network and Network Queue QoS Policy Types
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.
