Cisco Firepower 1140 Firewalls Etherchannel

[ahmed-ejaz]

Hi,

I have a pair of Cisco 1140 FTD appliances configured in HA. For the Internal network I was planning on creating an Etherchannel using two firewall interfaces to connect to our Core switches stack and use subinterfaces/VLANs for various Zones. I was not able to find an option to create an Etherchannel when browsing the Interface section and can only see Bridge Interfaces and Subinterfaces option in the GUI.

As per my understanding and after reading the documentation, the model 1140 does not support Etherchannels? or do I need to upgrade the firmware on the firewalls to get this feature?

Thank you,

Regards,

Ahmed
