Is it possible to enable DHCP-Server on Management Interface?

L1 Bithead

Hi, I would like to know, if there is a way to enable DHCP-Server on management interface? We are using another interface for management so we could enable DHCP-Server on the dedicated management interface. In case of need we can establish a physical connection between the management interface and a laptop.

Hi, of course there are many ways and workarounds to handle this. The reason for my question is to make it easier for our admins to connect to the device in case of loosing any other connection. (I haven't tried so far, but I think it is possible to deny the access through policy rules??) So, if I could use DHCP on management interface I could easily plug in my notebook and get a new connection without rembering IP-settings on this interface. It is more or less playing around, we will use it without DHCP on management interface.

In that case I would setup static ip on the mgmt interface and connect that to your mgmt network and at the same time create a management profile which only allows ssh/https/ping and connect that to a dedicated dataplane interface (like the last one or so) along with setup a dhcp server profile which you attach to the same dedicated dataplane interface.

Dont forget to put this in its own VSYS if possible (along with its own VROUTER).

This way your technician(s) can use either the dedicated mgmt-network OR connect directly to the PA device on the last dataplane interface (or which one you choose) by DHCP.

Another method is to simply use static ip on the mgmt dataplane interface (along with VSYS and VROUTER) - this way your technician(s) knows that last interface always uses (or whatever) and is for mgmt being directly attached when you have physical access to the box.

The point of VSYS/VROUTER is to isolate it as much as possible from the other dataplane interfaces.
