Hi,

The number of redundant interface is a number between 1 and 8.


I hope this helps.

Best regards.

Massimiliano.

But my intent is to setup sub-interfaces. You are suppose to be able to setup a maximum of 8 redundant interfaces. the ASA only have 5 physical interfaces (including management). So how can you setup 8 interfaces without using sub-interfaces.

Never mind. I just figured it out. What needs to happen is you need to create the redundant interface first. Add the member interfaces. Then you are able to create the sub-interfaces for the redundant interfaces. See below:


ASA(config)# int redundant 2

ASA(config-if)# member-interface e0/3

INFO: security-level and IP address are cleared on Ethernet0/3.

ASA(config-if)# member-interface e0/2

INFO: security-level and IP address are cleared on Ethernet0/2.

ASA(config-subif)# int redundant 2.2

ASA(config-subif)# vlan 2

ASA(config-subif)# nameif DMZ

INFO: Security level for "DMZ" set to 0 by default.

ASA(config-subif)# security 30

ASA(config-subif)# ip address 20.20.20.20 255.255.240.0

ASA(config-subif)# sh run int red 2.2

!

interface Redundant2.2

vlan 2

nameif DMZ

security-level 30

ip address 20.20.20.20 255.255.240.0

ASA(config-subif)#
