CLI: DiffServ for VoIP
The following example configures DiffServ VoIP support:
Enter Global Config mode. Set queue 5 on all ports to use strict priority mode. This queue shall be used for
all VoIP packets. Activate DiffServ for the switch.
(Netgear Switch) #config
(Netgear Switch) (Config)#cos-queue strict 5
(Netgear Switch) (Config)#diffserv
Create a DiffServ classifier named 'class_voip' and define a single match criterion to detect UDP packets.
The class type “match-all” indicates 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
