Quality of Service: Managing Bandwidth More Effectively
Globally-Configured QoS
5-66
Syntax: interface < port-list > qos dscp < codepoint >
The DSCP 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)
Syntax: no interface [e] < port-list > qos
Removes a QoS classifier for the specified source-port(s).
Syntax: show qos source-port
Displays a listing of all source-port QoS classifiers currently
in the running-config file.
Example. In this example, you assign the following DSCP policies (code-
point and associated 802.1p priority) to matching packets with the specified
source-ports:
Source-Port DSCP
A2 000111
B1-B3 000101
B4, C2 000010
1. Determine if the DSCP codepoints that you want to use to mark matching
packets already have an 802.1p priority assigned, which could indicate
use by existing applications (show qos dscp-map command). This is not a
problem as long as the configured priorities are acceptable for all appli-
cations using the same DSCP.
Also, note that a DSCP must have an 802.1p priority configured before you
can use it to mark matching packets. If necessary, use the qos dscp-map
< codepoint > priority < 0 - 7 > command to configure the DSCP policy
(codepoint and associated 802.1p priority) that you want to use to mark
matching packets.
