Using the Management Interface of the Cisco ASA Firewall

Using the Management Interface of the Cisco ASA Firewall

All Cisco ASA firewall models from 5510 and higher, include an extra ethernet interface for management. By default, this specific interface is set to management-only mode, which means that it can receive traffic only, but it does not allow traffic to pass through to other interfaces.

In order to enable the Management 0/0 interface to act as a normal Firewall interface, use the following configuration:

asa (config)# interface management 0/0
asa (config-if)# no management-only

With the above, you just added one more normal firewall interface to your appliance since the management interface can now pass through traffic just like any other interface.
