Aggregation interface on virtual wire

L3 Networker

Hello All,

Is there supported to create virtual wire aggregate group ae1 with 3 physical interfaces and another ae2 with another 3 physical interfaces, then form virtual wire with ae1 and ae2. Point of this setup is to put PA between two switches with port channel group formed with 3 physical interfaces.

Hi Tician,

It is supported, be cautious about trunking protocol configuration on cisco.

This tech note outlines the process for a two interface bundle, but the same procedure can be used for three.  Naturally, the two AE will be separate v-wires but you can put them into the same zones.

This doc is good, but I considering case where trunk with multiple vlan's are deployed a cross port channel. If you don't aggregate this links on pan, that's mean that you need deploy two vwire interfaces from one switch to same security zone. But how can I make policies to secure traffic between two vlan's on this particular formed vwire. Should I create subinterfaces with vlan tag membership, or just make policies by source and destination IP, users and so on...?

If I understand you correctly, your AE bundle is also a Q tag trunk port.  In that case you simply create the subinterfaces on the AE interface and match the tags.

Ok, just clarify what I want to do.

To put PAN between two Cisco switches with Q trunk formed on port channel with two physical port. So I configured two physical VWires without aggregation and corresponded vlan subinterfaces with vlan tag respectively. Then I create Vwires interfaces of same vlan's. Then new created vwire side subs in same vlan, put on same security zone eg. Vwire_10 zone. On second physical Vwire I need to create same vlan subs and put them on corresponded sec zone eg. Vwire_10. On that point I create security policies to secure traffic between vlan's (eg. Vwire_10 to Vwire_50). Maybe picture below is better to help understand this setup than I could explain...

I have no enough resources to test this and I'm concerned whether is this recommended scenario or not, when we talk about Vwire setup on trunk link's with aggregated interfaces on switches?

for this case I recommend to use layer 2 interface because vwire is only for physical interface and aggregate interface. You can improve on the following solutions:
