dear all 

 

i need your help in below points which an issue i spent couple of hours but i cant resolve so i need to get some help from your great and valued information :

 

1- i cant enter to enable or exec mode ( before i can but maybe after changed the admin password from the firepowe gui (fmc) i think some privilege were disappeared for this user 

so is there any way to get the enable mode or to create new user with full privilege ? 

 

2- as im not able to enter to enable mode to configure ip helper address on asa ftd so im able to access via web normally but i dont know how to add the dhcp  servers or dhcp relay agent 

so what is the steps to add the helper address or on asa it called dhcp relay agent ?? where should i add ?

 

i already have 2 dhcp server and i dont know how via FMC (firepower GUI) to add them so i can get the dhcp parameters from main data center not from local dhcp service

Re: cant enter to enable mode + how to add helper address on Cisco ASA5516-X Threat Defense (75) Version 6.2.3.3

When you run Firepower Threat Defense (FTD) almost all configuration commands are done from the manager GUI. (Firepower Management Center (FMC), the local manager Firepower Device Manager (FDM) or cloud-based manager Cisco Defense Orchestrator (CDO)).

Instructions for configuring DHCP relay using FMC can be found here:

https://www.cisco.com/c/en/us/support/docs/security/firepower-ngfw/200475-Configure-DHCP-Server-Relay-on-FTD-Using.html

I don't think DHCP relay configuration for FDM- and CDO-managed FTD appliances is supported as of the current Firepower 6.6.

There is no enable mode in the ftd cli shell. If you drop to the diagnostic cli there is enable mode but it still doesn't allow you to make configuration changes.

Config changes must be made in the GUI except for a VERY small number of things you can do in the cli.

Re: cant enter to enable mode + how to add helper address on Cisco ASA5516-X Threat Defense (75) Version 6.2.3.3

so from what u r saying there are no enable mode and config mode to configure the Fw so what os the purpose then of the cli if not anle to configure any?! just show ?!

so i have now 2 helper address and i need to configure them ?! how ?! 

 

note : my network contains core switch 3850 and the local dhcp configured on it but the gateways on Fw ?! so is there any optiom to configure the helper on switch if im not allowed to do it on fw?!!

Re: cant enter to enable mode + how to add helper address on Cisco ASA5516-X Threat Defense (75) Version 6.2.3.3

The cli shell can be used for show commands, some diagnostic/ troubleshooting commands and a (very) limited number of configuration commands.

99% of all FTD configuration must be done through the GUI (not mentioning API for purposes of this discussion).

I already provided the link to the FMC configuration guide section on configuring the DHCP relay feature. Did you read that?

Re: cant enter to enable mode + how to add helper address on Cisco ASA5516-X Threat Defense (75) Version 6.2.3.3

yes definitely i go through link and when i try to apply on fw so i didnt find dhcp relay

its only dhcp server  and cofigure dhcp option ... they mentioned image version should 6.0 and above and im running 6.2.3

 so thats why im asking?!! 

 

the firewall i can connect via ssh and telnet but the no enable mode so i cam configure but seems i cant so thats why im asking?!

 

also i mentioned that i have core switch maybe i have the chance to configre the helper address on it if the asa will not aupport me ob this?!!

Can you share a screen shot of your device management page, DHCP tab and show me what it looks like?

I don't have a FMC 6.2.3 to verify but I did check FTD devices on version 6.3, 6.4 and 6.6 FMCs and see the option for DHCP relay on all of them.

Re: cant enter to enable mode + how to add helper address on Cisco ASA5516-X Threat Defense (75) Version 6.2.3.3

You're using the local Firepower Device Manager - FDM.

As I mentioned in my 29 July reply, DHCP relay configuration for FDM- and CDO-managed FTD appliances is not supported as of the current Firepower 6.6. (The same shortcoming applies to the upcoming 6.7 as well.)

You need to use an external Firepower Management Center (FMC) to be able to configure the more advanced features.

FMC is a separate product that requires you purchase and install it on a VMware ESXi server.

No version of FDM-managed FTD currently supports DCHP helper without having FMC to configure the feature.
