ME3400 limited CDP entries

[DEENA VERAPPAN]

I have the ME3400 deployed in an the following design. 8 100Meg ports connects to Cisco 2955s, and the 1Gig port uplinks to a Cisco 3560. My CDP neighbour table only shows an entries for the uplink Gig port. If I look at the CDP stats in the show cdp Interfaces Fastethernet 0/1,, I see CDP packets being sent every 60, but nothing returning.

Anyone encountered this or knows of a fix??

THanks

Hi,

Is CDP enabled on the 2955s?

yes, it is, and cdp packets are being sent from the 2955 to the ME3400.

Thanks for your help

Ok, can you do a sh and no sh on one of the ports connection to the 2955 and test again?

In this does not help, can you unplug the port and plug it back in to see if CDP gets reset?

I've power cycled 2 of the 2955s. I have a total of 8 2955s connected on ports 1 - 8. Non of these ports show any CDP neighbours, only the uplink port has a CDP neighbour, so I don't believe it to be the 2955s, and I find it hard to believe that CDP would not be allowed on the FastEthernet ports, weird isn't it...

Thank u again
