Starting Interface Configuration (ASA 5510 and Higher)
• Clearing the running configuration and immediately applying a new configuration will minimize the
downtime of your interfaces. You will not be waiting to configure the interfaces in real time.
Step 1 Connect to the ASA; if you are using failover, connect to the active ASA.
Step 2 If you are using failover, disable failover by entering the no failover command.
Step 3 Copy the running configuration by entering the more system:running-config command and copying the
display output to a text editor.
Be sure to save an extra copy of the old configuration in case you make an error when you edit it.
Step 4 For each in-use interface that you want to add to a redundant or EtherChannel interface, cut and paste
all commands under the interface command to the end of the interface configuration section for use in
creating your new logical interfaces. The only exceptions are the following commands, which should
stay with the physical interface configuration:
• media-type
• speed
• duplex
• flowcontrol
Note You can only add physical interfaces to an EtherChannel or redundant interface; you cannot have
VLANs configured for the physical interfaces.
Be sure to match the above values for all interfaces in a given EtherChannel or redundant
interface. Note that the duplex setting for an EtherChannel interface must be Full or Auto.
For example, you have the following interface configuration. The bolded commands are the ones we
want to use with three new EtherChannel interfaces, and that you should cut and paste to the end of the
interface section.
