2960 port config for both PC & SIP phone using QoS
It has been a long time since I have done this, and I am just looking for confirmation.
Below is a snippet of a configuration from a 2960 Cisco Catalyst switch.
Will the configuration below for port 36 actually provide QoS when an IP phone is plugged into it?
description Standard port configuration
description LAN port to support PC or VoIP config
mls qos trust cos
spanning-tree bpduguard enable
ip address 172.21.2.3 255.255.0.0
no ip route-cache
ip default-gateway 172.21.1.10
What I KNOW works is that when you plug a PC or a VoIP phone in, both work on the VLAN1 as defined. But I do not know if QoS is working when an IP phone is plugged in.
