NETGEAR 7000 Series Managed Switch Administration Guide Version 7.2
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)
Create a DiffServ classifier named 'class_voip' and define a sin- gle 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)
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)
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)
Attach the defined policy to an inbound service interface.
