Re: CDP

Do I have to copy my post? "MOSTLY USELESS" It's only value is in Cisco Proprietary setups... telling a CISCO ip phone what it's voice vlan is, CISCO smartport configuration, etc. Despite VMware's support of CDP, none (Z-E-R-O) of the dozens of ESX/ESXi hosts in my network are visible -- the nexus 1000V's do, as does an ancient 2950.

*I* turn it off -- and have for 20 years. It's one less source of broadcast noise in the network. It's one less resource drain on the switch / router (both CPU and memory) -- those little vampires add up. It has never had a meaningful use in any network I have managed; it can only tell you about cisco devices attached to cisco devices.
