Network QoS Policy Commands
Network QoS Policy Commands (for 7210 SAS M in access uplink mode)
network
Syntax [no] network network-policy-id
Context config>qos
This command creates or edits a QoS network policy. The network policy defines the treatment
Description
packets receive as they ingress and egress the access uplink port.
The QoS network policy consists of an ingress and egress component. The ingress component of
the policy defines how Dot1p bits are mapped to internal forwarding class and profile state. The
forwarding class and profile state define the Per Hop Behavior (PHB) or the QoS treatment
through the 7210 SAS. The mapping on each network interface defaults to the mappings defined in
the default network QoS policy until an explicit policy is defined for the network interface. It also
defines the rate-limiting parameters for the traffic mapped to each forwarding classes. Traffic
mapped to each forwarding class can be rate limited using separate meters for each uni-cast and
multipoint traffic.
The egress component of the network QoS policy defines the queuing parameters associated with
each forwarding class. There are eight queues per port on the egress. Each of the forwarding
classes is associated with a queue on each access uplink port. This queue gets all the parameters
defined within the default network QoS policy 1 until an explicit policy is defined for the network
interfaceaccess uplink port. If the egressing packet originated on an ingress SAP, the parameter is
always enabled for the access uplink port, the egress QoS policy also defines the Dot1p bit
marking based on the forwarding class and the profile state.
The network policy-id 1 cannot be modified or deleted. It defines the default Dot1p-to-FC
mapping and
Dot1p-to-FC mapping and default meters for unicast and multipoint meters for the ingress. For the
egress, it defines eight forwarding classes which represent individual queues and the packet
marking criteria.
If a new network policy is created (for instance, policy-id 2), only the default action, default
meters for unicast and multipoint traffic and egress forwarding class parameters are identical to the
default policy. A new network policy does not contain the default Dot1p-to-FC mapping for
network QoS policy of type port). The default network policy can be copied (use the copy
command) to create a new network policy that includes the default ingress Dot1p or DSCP to FC
mapping (as appropriate).
You can modify parameters or use the no modifier to remove an object from the configuration.
