Trunking between an IPS 4240 and an ASA 5510

[Kevin Melton]

I have a requirement at a client site wherein I am tasked with separating VLANs near the edge.

I have to have a trunk between the ASA and the IPS which will carry the two VLANs.

Is this possible?

Thank You in advance!

Hello Kevin,

I think this is better to posted on the IPS than the ASA Forum.

The ASA just needs to be configured with sub-interfaces.

On the IPS I think inline Vlan Pairs will work.

I found this link which explains it well.

I hope it helps

Thank you for the response.

is it correct to say then that the subinterfaces ont he ASA would be configured to trunk to a switch by creating subinterfaces just like you would on a router that you wanted to trunk to?

Thanks again!

Kevin,

That is correct.

Example:

interface g0/1.10

vlan 10

nameif outside1

ip address 10.10.10.1 255.255.255.0
