N2000 ISDP/CDP Problem
I have over 100 N2000 switches in my network, almost all connected to Cisco 4500x switches. As of firmware 6.2.6.6, the N2000s no longer show up in a "sh cdp neigh" on the Cisco switch.
Additionally, running a show cdp traffic on the Cisco switch shows a high number of invalid packets. Again, only switches that have Dell switches on 6.2.6.6 below them. 6.2.0.5 and 6.1.1.7 seem to be fine.
Is this a known issue? Is this fixable without a firmware update?

Hi,
It looks like 6.2.6.8 fixed some issues with ISDP. Can you try the latest firmware on one of the switches and see if it resolves the issue? http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=JTF27&fileId=3499688837&osCode=NAA&productCode=networking-n2000-series&languageCode=EN&categoryId=NI
