Measure trunk port vlan bandwidth

[tothz]

Hello

I have a cisco trunk port with allowed three different vlan. Are there any way to measure traffic of one vlan ?

GigabitEthernet 0/1

switchport mode trunk

switchport trunk allowed vlan 1,2,3

I woult like know vlan 3 traffic.

Thanks

Easily?  Like using some simple show command?  Without any additional configuration support?

I don't believe (?) so.

With some additional configuration support, possibly.  Much depends on your device(s) capabilities.

Some approaches that come to mind are:  ACL ACE's counters, QoS counters, netflow stats, etc.
