How do I configure voice VLAN and prioritize voice traffic using CLI commands on mymanaged switch?

The script in this article shows how to configure Voice VLAN and prioritize the voice traffic. Here the Voice VLAN mode is in VLAN ID 10.

Create VLAN 10.

(Netgear Switch) #vlan database (Netgear Switch) (Vlan)#vlan 10 (Netgear Switch) (Vlan)#exit
Include the ports 1/0/1 and 1/0/2 in VLAN 10.

(Netgear Switch) (Config)#interface range 1/0/1-1/0/2 (Netgear Switch) (conf-if-range-1/0/1-1/0/2)#vlan participation include 10 (Netgear Switch) (conf-if-range-1/0/1-1/0/2)#vlan tagging 10 (Netgear Switch) (conf-if-range-1/0/1-1/0/2)#exit
Configure Voice VLAN globally.

(Netgear Switch) (Config)# voice vlan
Configure Voice VLAN mode in the interface 1/0/2.

(Netgear Switch) (Config)#interface 1/0/2 (Netgear Switch) (Interface 1/0/2)#voice vlan 10 (Netgear Switch) (Interface 1/0/2)#exit
Create the DiffServ class ClassVoiceVLAN.

(Netgear Switch) (Config)#class-map match-all ClassVoiceVLAN
Configure VLAN 10 as the matching criteria for the class.

(Netgear Switch) (Config-classmap)#match vlan 10
Create the DiffServ policy PolicyVoiceVLAN.

(Netgear Switch) (Config)#policy-map PolicyVoiceVLAN in
Map the policy and class and assign them to the higher-priority queue.

(Netgear Switch) (Config-policy-map)#class ClassVoiceVLAN (Netgear Switch) (Config-policy-classmap)#assign-queue 3 (Netgear Switch) (Config-policy-classmap)#exit
Assign it to interfaces 1/0/1 and 1/0/2.

(Netgear Switch) (Config)#interface range 1/0/1-1/0/2 (Netgear Switch) (conf-if-range-1/0/1-1/0/2)# service-policy in PolicyVoiceVLAN
