Netgear M4100-D12G (GSM5212v1h1) - 10‐port GE + 2 GE Combo L2 Managed PD Switch Guía De Administador

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 
(according to the class_ef definition), or marks UDP packets according to 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

Set queue 5 on all interfaces to use strict mode.
