Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Types To Configure QoS for Outbound Traffic
6-50
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 type for the specified VLAN.
show qos vlan-priority
Displays a listing of all QoS VLAN-ID types currently in the
running-config file.
For example, suppose you wanted to assign this set of priorities:
VLAN-ID
DSCP
40
000111
30
000101
20
000010
1
000010
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 types to use it.)

The DSCPs for this
example have not yet
been assigned an
802.1p priority level.
