Create Class Maps
Create the Policy Maps
No "priority" statement has been set in this Policy Map. This is because the Fast Ethernet
outbound queue is assumed not to be congested due to the ingress traffic coming from the
serial interface being much lower than 100Mbps of the Fast Ethernet interface. If the Fast
Ethernet is congested for other traffic reasons then a "priority" statement will be required on
the Fast Ethernet sub-interface Policy Map as well.
Router1(config)# class-map match-all MitelClassMapIn
Router1(config-cmap)# match access-group name Mitel [Matches the ACL created above]
Router1(config)# class-map match-all MitelClassMapOut
Router1(config-cmap)# match ip dscp ef [Matches the DSCP value of 46]
Router1(config)# policy-map MitelPolicyIn [Only required if default DSCP is being changed]
Router1(config-pmap)# class MitelClassMapIn [Matches the class map looking for Mitel traffic]
Router1(config-pmap-c)# set ip dscp ef [Overwrite DSCP bits with a value of 46]
Router1(config)# policy-map MitelPolicyOut
Router1(config-pmap)# class
MitelClassMapOut
[Matches the class map looking for DSCP 46]
Router1(config-pmap-c)# priority percent 30 [Mitel traffic is guaranteed 30% of the bandwidth]
Or
Router1(config-pmap-c)# priority "bandwidth" [Alternatively specify actual bandwidth amount]
Router1(config-pmap-c)# exit
Router1(config-pmap)# class class-default [What to do with other traffic]
Router1(config-pmap-c)# fair-queue
Note: Priority is specified in either Percent or Bandwidth, NOT both.
Router1(config)# class-map match-all
MitelClassMapP-Bit
Router1(config-cmap)# match ip dscp ef [Matches the DSCP value of 46]
Router1(config)# policy-map MitelPolicyMapP-Bit
Router1(config-pmap)# class MitelClassMapP-Bit [Matches the class map looking for DSCP 46]
Router1(config-pmap-c)# set cos 6 [set the 802.1p bit to 6 if DSCP = 46]
