Creating And Applying A New Priority Map; Removing Or Disabling Per-Port Priority Map - Cabletron Systems SMARTSWITCH ROUTER 9032578-05 User's Reference Manual

You can create one or more priority maps that are different from the default priority map
and then apply these maps to some or all ports of the SSR. The new priority mapping
replaces the default mappings for those ports to which they are applied.

Creating and Applying a New Priority Map

To specify a priority map on a per-port basis, enter the following commands in Configure
mode:
Create a new priority
mapping.
Apply new priority
mapping to ports.
For example, the following command creates the priority map "all-low" which maps all
802.1p priorities to the "low" internal priority queue:
qos create priority-map all-low 0 low 1 low 2 low 3 low 4 low 5 low 6
low 7 low
Once a priority map is created, it can then be applied to a set of ports, as shown in the
following example:
qos apply priority-map all-low ports et.1.1-4, gi.4.*
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."
qos create priority-map no-ctrl 7 high

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.
The ability to specify per-port priority maps is enabled on the SSR by default. You can
disable use of per-port priority maps on the SSR; all ports on the SSR will then be
