I have a 2960 switch with the following configuration to provide voice for Avaya phone. Without any third party tools, are there any useful Cisco commands can show the usage of the voice and data traffic of each port? Thanks in advance.
interface GigabitEthernet1/0/4
switchport access vlan 20
switchport voice vlan 10
mls qos trust cos
no cdp enable
spanning-tree portfast
spanning-tree bpduguard enable
