Migrating from FWSM to ASA Service Module (ASASM)

Alan Boyd
Level 1
Level 1

I'm migrating from a failover pair of FWSM modules across to a failover pair of ASA Service Modules. In order to avoid a "big bang" switchover I intend to migrate subnets from one to the other over a protracted period.

With that in mind, can anyone confirm whether there is any restriction on having FWSM and ASASM modules in the same chassis? A trawl of the relevant documentation hasn't revealed anything.

In this specific case it is Catalyst 6509E VSS chassis pairs with Sup-2T.

Thanks in advance.

So long as the chassis has enough power to power these modules you are good.

Upto 4 FWSMs can be installed in a chassis.

Upto 4 ASA-SM modules can be installed in a chassis.

Q. How many ASA Services Modules can I place in a Cisco Catalyst 6500 Series chassis?

A. Up to four independent ASA Services Modules can simultaneously run in a Cisco Catalyst 6500-E Series chassis.
