Configuring and applying QoS policies other than the default policy is optional. A default network policy of the type ip-interface is applied to each IP interface.
To create an network QoS policy of the ip-interface type when operating in network mode, define the following:
Specify a network policy ID value. The system does not dynamically assign a value.
Set the network-policy-type parameter to ip-interface.
Include a description that provides a brief overview of policy features.
Use egress marking and remarking to specify the egress LSP EXP marking map; otherwise, the default values are applied. The following are defined:
remarking
The remark policy-id command specifies the policy, which defines the mapping of the FC-to-packet header priority profile and bits.
The remarking command uses the associated policy configured with the remark policy-id command to determine which priority bits to mark on egress.
When remarking is enabled, MPLS EXP bits for all MPLS LSR and LER traffic are marked on egress on the specified network IP interface. Remarking is based on the FC-to-LSP EXP bit mapping that is defined in the remark policy and associated under the egress node of the network QoS policy. The EXP marking values used depend on the configured remark policy. If the user does not attach an explicit policy, the default policy is used.
When remarking is disabled for MPLS LSR traffic, EXP values received on ingress are not modified on egress. For MPLS LER traffic where the node adds the MPLS encapsulation, MPLS EXP bits are set based on the mapping specified in the policy associated with the IP interface. If the user does not attach an explicit policy, the default policy is used.
FC criteria
The FC name represents an egress queue. Specify FC criteria to define the egress characteristics of the queue and the marking criteria of packets flowing through it.
LSP EXP
The EXP is used for all packets requiring marking that egress on this FC queue that are in or out of profile.
Specify ingress criteria using the following:
default action
Defines the default action to take for packets that have undefined bits set. The default action specifies the FC to which these packets are assigned.
LSP EXP
Creates a mapping between the LSP EXP bits of the network ingress MPLS traffic and the FC. Ingress MPLS traffic that matches the specified EXP bits are assigned to the corresponding FC. The user has an option to specify the mapping of the LSP EXP bits to a profile (in or out). Ingress traffic that matches the specified EXP bits is assigned the corresponding profile.
Use the following syntax to create a network QoS policy.
