Quality of Service (QoS): Managing Bandwidth More Effectively

Using QoS Classifiers To Configure QoS for Outbound Traffic

Syntax: vlan < vid > qos dscp < codepoint >

Assigns a DSCP policy to packets carrying the specified IP

address, and overwrites the DSCP in these packets with the

assigned <

codepoint > value. This policy includes an 802.1p

priority and determines the packet’s queue in the outbound

port to which it is sent. If the packet leaves the switch on a

tagged port, it carries the 802.1p priority with it to the next

downstream device. (Default:

No-override)

no vlan < vid > qos

Removes QoS classifier for the specified VLAN.

show qos device-priority

Displays a listing of all QoS VLAN-ID classifiers currently

in the running-config file.

For example, suppose you wanted to assign this set of priorities:

VLAN-ID DSCP Priority

40 000111 7

30 000101 5

20 000010 1

1 000010 1

1. Determine whether the DSCPs already have priority assignments, which

could indicate use by existing applications. This is not a problem as long

as the configured priorities are acceptable for all applications using the

same DSCP. (Refer to the “Note On Changing a Priority Setting” on page

6-61. Also, a DSCP must have a priority configured before you can assign

any QoS classifiers to use it.)

The DSCPs for this

example have not yet

been assigned an

802.1p priority level.
