Hi,

You can check this in the configuration guide for the ASA.

But in the likelyhood that you are not finding the command to create the actual interface then I would have to guess that you are not running a software level new enough to support Etherchannel/Port-channel.

You will require 8.4(1) software atleast on the ASA to be able to configure Etherchannel/Port-channel

This is from the Release notes

Interface Features

EtherChannel support (ASA 5510 and higher)

You can configure up to 48 802.3ad EtherChannels of eight active interfaces each.

Note You cannot use interfaces on the 4GE SSM, including the integrated 4GE SSM in slot 1 on the ASA 5550, as part of an EtherChannel.

We introduced the following commands: channel-group, lacp port-priority, interface port-channel, lacp max-bundle, port-channel min-bundle, port-channel load-balance, lacp system-priority, clear lacp counters, show lacp, show port-channel.

We introduced or modified the following screens:

Configuration > Device Setup > Interfaces

Configuration > Device Setup > Interfaces > Add/Edit EtherChannel Interface

Configuration > Device Setup > Interfaces > Add/Edit Interface

Configuration > Device Setup > EtherChannel

Here is a link to the configuration guide explaining the configuration steps

Hope this helps
