3. Create a second DiffServ classifier named ‘class_ef’ and define a single match criterion to detect a DiffServ
code point (DSCP) of ‘EF’ (expedited forwarding). This handles incoming traffic that was previously
marked as expedited elsewhere in the network.
class-map match-all class_ef
match ip dscp ef
exit
4. Create a DiffServ policy for inbound traffic named ‘pol_voip’, and then add the previously created classes
‘class_ef’ and ‘class_voip’ as instances within this policy.
This policy handles incoming packets already marked with a DSCP value of ‘EF’ (per ‘class_ef’ definition),
or marks UDP packets per the ‘class_voip’ definition) with a DSCP value of ‘EF’. In each case, the matching
packets are assigned internally to use queue 5 of the egress port to which they are forwarded.
policy-map pol_voip in
class class_ef
assign-queue 5
exit
class class_voip
mark ip-dscp ef
assign-queue 5
exit
exit
Attach the defined policy to an inbound service interface.
