ProSafe M4100 and M7100 Managed Switches

2.Create a DiffServ classifier named class_voip and define a single match criterion to detect UDP packets. The class type match-allindicates that all match criteria defined for the class must be satisfied in order for a packet to be considered a match.

(Netgear Switch) (Config)#class-map match-all class_voip (Netgear Switch) (Config class-map)#match protocol udp (Netgear Switch) (Config class-map)#exit

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

4.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

5.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
