is there is a way to create vlans on asa 5520. i am looking at assigning two asa ports on a single vlan.
Please help with suggestions.
Thanks in advance.
Redundant interface is a way of creating backup interfaces on the firewall. It is something similar to EtherChannel but with the difference that, unlike in etherchannel, the firewall uses only one interface for data transfer. The other interface will be used as a backup interface. When the primary interface goes down, the secondary interface will takeover. Other than that, as August has pointed out, you configure the redundant interface just like any other interface and give it an IP in the range of your inside interface. When you configure redundant interface, you do not configure individual interfaces (Something similar to etherchannels where changes are made on the PO interface).
Hope this helps.
