set ip dscp
This command modifies the IP DSCP value in a matching packet (as specified by the match
command). Use the no form to remove this traffic classification.
Syntax
[no] set ip dscp new-dscp
new-dscp - New Differentiated Service Code Point (DSCP) value. (Range: 0-63)
Default Setting
None
Command Mode
Policy Map Class Configuration
Command Usage
The set ip dscp command is used to set the priority values in the packet’s ToS field for matching
packets.
Example
This example creates a policy called “rd-policy,” uses the class command to specify the previously
defined “rd-class,” uses the set ip dscp command to classify the service that incoming packets will
receive, and then uses the
police flow command to limit the average bandwidth to 100,000 Kbps,
the burst rate to 4000 bytes, and configure the response to drop any violating packets.
Console(config)#policy-map rd-policy
Console(config-pmap)#class rd-class
Console(config-pmap-c)#set ip dscp 3
Console(config-pmap-c)#police flow 10000 4000 conform-action transmit
violate-action drop
Console(config-pmap-c)#
set phb
This command services IP traffic by setting a per-hop behavior value for a matching packet (as
specified by the
match command) for internal processing. Use the no form to remove this setting.
Syntax
[no] set phb phb-value
phb-value - Per-hop behavior value. (Range: 0-7)
Default Setting
None
