Packet trace and spanning

[SHAIHAN JAFFREY]

I have 2 core switches hsrp running between. Three access layer switches are connected to these core switches. Vlan 220 configured on the core switches with vtp running.

How do I accomplish the below mentioned points on my network to troubleshoot interVlan leakage.

- Fully detailed physical layer packet trace of Vlan220, to check for any device in between that could be

leaking the pkts or causing a loop

- Sniffer traces - spanning the ports interconnecting Vlan220

I don't understand your question.  You are attempting to avoid inter-vlan leakage, but from your description there is only one vlan.  Inter-vlan traffic is considered traffic between two or more vlans.

Yes it is between two vlans. The other vlan is a voice vlan 221 on the same switch.
