cisco device connected to other vendor

Looks like the application failed to find connectivity when a device that supports CDP or LLDP is connected to a device that does not support any of these protocols.

I suspect that the reason is that if one device support CDP then it expect that all attached device will support CDP as well.

However this is not the situation and there are lots of other devices connected to Cisco devices (Juniper, F5, checkpoint..)

So there should be an option to force bridge table based mapping for such connections
