Dear all,
According to the folloiwng output, I think Catalyst8500's CDP is disabled on interface level by default right?
Cat85(config)#cdp run
Cat85(config)#end
Cat85#sh cdp interface gigabitEthernet 0/0/0
CDP is not enabled on interface GigabitEthernet0/0/0
Cat85#sh run int g0/0/0
Building configuration...
Current configuration : 71 bytes
!
interface GigabitEthernet0/0/0
no ip address
negotiation auto
end
If I see the follwoing manual, CDP is enable on global configuration level however it does not say any default information on interface level. I appreciate if you can let me know any related information if this behavior is Catalyst8500 special.
