Traffic Prioritization for Layer-2 Flows

Creating and Applying a New Priority Map

To specify a priority map on a per-port basis, enter the following commands in Configure

mode:

For example, the following command creates the priority map “all-low” which maps all

802.1p priorities to the “low” internal priority queue:

Once a priority map is created, it can then be applied to a set of ports, as shown in the

following example:

In the above example, ports et.1.1-4 and ports gi.4.* will use the “all-low” priority map.

All other ports, including ports et.1.5-8, will use the default priority map.

You do not need to specify mappings for all 802.1p values. If you do not specify a

particular mapping, the default mapping for that 802.1p priority is used. The following

example creates a priority map “no-ctrl” with the same mappings as the default priority

map, except that the 802.1p priority of 7 is mapped to the internal priority “high” instead

of “control.”

Removing or Disabling Per-Port Priority Map

Negating a qos create priority-map command removes the priority map. (Before you can

remove a priority map, you must negate all commands that use the priority map.)

Negating a qos apply priority-map command causes the configured ports to use the

default priority mapping.

Create a new priority

mapping.

qos create priority-map <name> <CoS number>

control|high|medium|low

Apply new priority

mapping to ports.

qos apply priority-map <name> ports <port-list>

qos create priority-map all-low 0 low 1 low 2 low 3 low 4 low 5 low 6 low 7 low

qos apply priority-map all-low ports et.1.1-4, gi.4.*

qos create priority-map no-ctrl 7 high
