FTD 3105 adn 3110 management port

Josue YGS — Tue, 15 Oct 2024 15:33:07 GMT

Hello,

I have a question, I know that the management port of the FTD 3100 family should be considered a GBIC for interconnection, but I was wondering if it is possible to configure another copper port on the FTD to use it as a management port.

Regards,

Josué Gaytán

If you login into the FTD via console, you can use the command "configure network management-data-interface" and follow the interactive menu. Before you do so please make sure that the original management interface is not configured in DHCP, otherwise this wouldn't work.

Note that the method suggested by @Aref Alsouqi is for using a DATA interface in double duty also for management. It does not assign the interface to be management only.

Hi Aref,

I put the command on the FTD 3110 and it doest work, the CLI show me the next error: Error: This command is not supported when FDM(On Box Management) is enabled

Then i try to change the port of management from the FMC following the next link No title (cisco.com)

Can you give me more information about?

Kind regards.

Correct - FDM has limitations that FMC does not. That's why engineers with experience using both always strongly prefer FMC-based management.

Sorry I didn't know you are managing this firewall locally with FDM. Are you planning to connect this firewall to an FMC? If not I'm not sure if there is any workaround to this but using the dedicated management port. However, if you are planning to connect this firewall to an FMC maybe you can try to configure the FMC as a manager and then try to reissue the command "configure network management-data-interface", not sure if this will work.
