NETGEAR 7000 Series Managed Switch Administration Guide Version 7.3
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 somewhere in the network.
(Netgear Switch) (Config)#class-map match-all class_ef
(Netgear Switch) (Config class-map)#match ip dscp ef
(Netgear Switch) (Config class-map)#exit
Create a DiffServ policy for inbound traffic named 'pol_voip', 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.
(Netgear Switch) (Config)#policy-map pol_voip in
(Netgear Switch) (Config policy-map)#class class_ef
(Netgear Switch) (Config policy-class-map)#assign-queue 5
(Netgear Switch) (Config policy-class-map)#exit
(Netgear Switch) (Config policy-map)#class class_voip
(Netgear Switch) (Config policy-class-map)#mark ip-dscp ef
(Netgear Switch) (Config policy-class-map)#assign-queue 5
(Netgear Switch) (Config policy-class-map)#exit
(Netgear Switch) (Config policy-map)#exit
Attach the defined policy to an inbound service interface.
(Netgear Switch) (Config)#interface 1/0/2
(Netgear Switch) (Interface 1/0/2)#service-policy in pol_voip
(Netgear Switch) (Interface 1/0/2)#exit
(Netgear Switch) (Config)#exit
