ASA Redundant Interfaces

Jim Kerr — Tue, 12 Mar 2019 06:58:38 GMT

Hi All

I have a Cisco ASA 5550 that already has 4 physical interfaces used which includes the use of 8 redundant interfaces under redudant1.

I am planning on using some of the spare physical interfaces shortly but wanted to use redundant interfaces also.

I've read on the Cisco pages that the ASA can only have a maximum of 8 redundant interfaces.

My question is on my ASA can I create another Redundant Interface2 and have another 8 spare redundant interfaces to use ? or does it mean that because the ASA already has 8 Redundant interfaces set up that I cannot do this ?

thanks

I don't really understand

I don't really understand what you are having at the moment as for example a redundant interface can't have eight members.

This is how it works:

You can have up to eight logical redundant interfaces. These interfaces hold your nameif, sec-level and ip-address.
Each logical redundant interface has two physical member-interfaces. These member interfaces are exclusivly bound to the logical redundant interface that uses them.
With an 5550 you can have a maximum of four redundant interfaces with two member interafces each. All eight interfaces of the 5550 are used that way.
If you connect these interfaces to you own infrastructure, using Etherchannel interfaces instead of redundant interfaces could be a better solution.
