NETGEAR NETGEAR user manual Assign-queue, Drop, Mark secondary-cos

User Manual for the NETGEAR 7300S Series Layer 3 Managed Switch Software

The DiffServ CLI does not necessarily require that users associate only one traffic class to one policy. In fact, multiple traffic classes can be associated with a single policy, each defining a particular treatment for packets that match the class definition. When a packet satisfies the conditions of more than one class, preference is based on the order in which the classes were added to the policy, with the foremost class taking highest precedence.

This set of commands consists of policy creation/deletion, class addition/removal, and individual policy attributes. Note that the only way to remove an individual policy attribute from a class instance within a policy is to remove the class instance and re-add it to the policy. The values associated with an existing policy attribute can be changed without removing the class instance.

The CLI command root is policy-map.

assign-queue

This command modifies the queue id to which the associated traffic stream is assigned. The queueid is an integer from 0 to n-1, where n is the number of egress queues supported by the device.

Format	assign-queue <queueid>
Mode	Policy-Class-Map Config
drop

This command specifies that all packets for the associated traffic stream are to be dropped at ingress.

Format	drop
Mode	Policy-Class-Map Config
mark secondary-cos

This command marks all packets for the associated traffic stream with the specified secondary class of service value (the inner 802.1Q tag of a double VLAN tagged packet) in the priority field of the 802.1p header. If the packet does not already contain this header, one is inserted. The CoS value is an integer from 0 to 7.

Format	mark secondary-cos <0-7>
Mode	Policy-Class-Map Config
