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.
