Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
ingress-class-map index-id
Example:
Router(config-ing-class-map)# ingress-class-map
1
Enters the ingress classification template settings for the
specified template ID and enables the configuration of the
classifications for IPv4, IPv6, or MPLS.
Step 4
map ip all queue strict-priority
Example:
Router(config-ing-class-map)# map ip all queue
strict-priority
Sets the priority for all IPv4 packets as high.
Step 5
map ip dscp-based
Example:
Router(config-ing-class-map)# map ip dscp-based
Enables classification based on the DSCP value in IPv4.
Step 6
map ip dscp dscp-value queue 0
Example:
Router(config-ing-class-map)# map ip dscp cs1
cs2 queue 0
Classifies IPv4 packets, with DSCP values cs1 and cs2 as
low-priority packets.
Step 7
map ip precedence-based
Example:
Router(config-ing-class-map)# map ip
precedence-based
Enables classification for IPv4 packets based on IP
precedence.
Step 8
map ip precedence precedence-value queue
strict-priority
Example:
Router(config-ing-class-map)# map ip precedence
5 7 queue strict-priority
Classifies the IPv4 packets, with precedence values 5 and 7
as strict priority.
Step 9
exit
Example:
Router(config-ing-class-map)# exit
Exits the ingress-class-map mode and goes back to the
global configuration mode.
