Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Types To Configure QoS for Outbound Traffic
.
Syntax: qos type-of-service diff-services < codepoint >
Causes the switch to read the < codepoint > (DSCP) of an
incoming IPv4 packet and, when a match occurs, assign a
corresponding 802.1p priority, as configured in the switch’s
DSCP table (page 6-59).
no qos type-of-service
Disables all ToS type operation.
no qos dscp-map < codepoint >
Disables direct 802.1p priority assignment to packets
carrying the < codepoint > by reconfiguring the codepoint
priority assignment in the DSCP table to
No-override. Note that
if this codepoint is in use as a DSCP policy for another
diffserv codepoint, you must disable or redirect the other
diffserv codepoint’s DSCP policy before you can disable or
change the codepoint. For example, in figure 6-15 you cannot
change the priority for the 000000 codepoint until you
redirect the DSCP policy for 000001 away from using
000000 as a policy. (Refer to “Note On Changing a Priority
Setting” on page 6-61. Refer also to “Differentiated Services
Codepoint (DSCP) Mapping” on page 6-58.)
show qos type-of-service
Displays current Type-of-Service configuration. In diffserv
mode it also shows the current direct 802.1p assignments
and the current DSCP assignments covered later in this
section.
