ASA 5500 Adding a DMZ Step By Step

The only difference for you is, if you are in active standby, you need to add an active and standby IP to the DMZ interface i.e

!
interface Ethernet0/2
 speed 100
 duplex full
 nameif DMZ
 security-level 0
 ip address 123.123.123.123 255.255.255.248 standby 123.123.123.124
!

Carry out all configuration on the primary active firewall, connect the same interfaces of both, to the DMZ, and Bobs yer uncle

That prety much depends on your topology, Im my case I prefer a DMZ to have its own switch, rather than relying on VLAN seperation. If I was deplying the solution to a government body, then I would have to have a physical seperation. But if you are not as concerned about security VLAN separation is adequate.
