...on a 2500. This doc does not list the 2500 as a supported platform for
the set ip dscp, and this can only be done on a route-map, the 'set ip dscp'
command is clearly missing from the policy-map commands, ergo, the question,
is there a way to map precedence to dscp on a 2500?
r2(config)#class-map SAMPLE
r2(config-cmap)#match access-g name SAMPLEFLOW
r2(config-cmap)#exi
r2(config)#policy-map POLICY1
r2(config-pmap)#class SAMPLE
r2(config-pmap-c)#?
QoS policy-map class configuration commands:
bandwidth Bandwidth
default Set a command to its defaults
exit Exit from QoS class action configuration mode
no Negate a command or set its defaults
police Police
priority Strict Scheduling Priority for this Class
queue-limit Queue Max Threshold for Tail Drop
random-detect Enable Random Early Detection as drop policy
service-policy Configure QoS Service Policy
shape Traffic Shaping
no 'set' command, only way is to use ip policy and route-map
r2(config)#route-map PRECEDENCE permit 10
r2(config-route-map)#match ip add TEST1
r2(config-route-map)#set ip ?
default Set default information
next-hop Next hop address
precedence Set precedence field
qos-group Set QOS Group ID
tos Set type of service field
