Using QoS Classifiers To Configure Quality of Service for Outbound Traffic
Syntax: qos type-of-service diff-services < current-codepoint > dscp
< new-codepoint >
Configures the switch to select an incoming IP packet carry­
ing the <current-codepoint > and then use the <new-codepoint>
to assign a new, previously configured DSCP policy to the
packet. The policy overwrites the <current-codepoint> with the
< new-codepoint > and assigns the 802.1p priority specified
by the policy. (Use the
priority for the DSCPs—page 8-62.)
Syntax: no qos type-of-service
Disables all ToS classifier operation. Current ToS DSCP
policies and priorities remain in the configuration and will
become available if you re-enable ToS diff-services.
Syntax: no qos type-of-service [diff-services < codepoint >]
Deletes the DSCP policy assigned to the
< codepoint > and returns the < codepoint > to the 802.1p
priority setting it had before the DSCP policy was assigned.
(This will be either a value from 0 - 7 or
Syntax: show qos type-of-service
Displays a listing of codepoints, with any corresponding
DSCP policy re-assignments for outbound packets. Also lists
the (802.1p) priority for each codepoint that does not have a
DSCP policy assigned to it.
For example, suppose you want to configure the following two DSCP policies
for packets received with the indicated DSCPs.
Received Policy
DSCP DSCP
001100 000010
001101 000101
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
8-65. Also, a DSCP must have a priority configured before you can assign
any QoS classifiers to use it.)
