HI

How u want to enable CDP i mean u want it to be enabled globally or at interface level.

If at globale level then

router(config)#cdp run to enable globally

router(config-if)# cdp enable at interface level.

it will not have any effect on network performance.

Thanks

Hi! The command works fine on my routers, but there's one router that's not able to enable the cdp on all the interfaces(not even one interface's cdp is enabled). I issued an cdp run command, but it doesn't take effect on the interfaces.

What might have caused this? any idea?

Thks!

router(config-if)#cdp enable

if u want it to enable at interface level.

Thanks

Hi!

There's only one switch that i'm not able to enable CDP globally, i do not need to do that individually on each interface and sub interfaces on other routers.

Any idea what's causing this problem?(i can do it on each interface individually) Just wonder why the global "CDP run" command is not working.
