I have a NEC IP PBX SV8100 connected to the access port of the C2960S switch and have configured the port as follows; the voice VLAN is VLAN 500
interface GigabitEthernet1/0/1
description "NEC UNIVERGE SV8100"
switchport access vlan 500
switchport mode access
spanning-tree portfast
end
should I add the following commands onto the switch port for proper handling of voice traffic, or what commands are appropriate for the list below if any or none, leave the configurations as above. I understand the configiures below are recommended for cisco IP Phones
Switch#configure t
Switch(config)#mls qos
Switch(config)#interface GigabitEthernet1/0/1
Switch(config-if)#switchport priority extend trust
Switch(config-if)#mls qos trust cos
Switch(config-if)#switchport voice vlan dot1p
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 500
Switch(config-if)#switchport voice vlan 500
