I connected a SMB SG300 series switch to an 2948G (CatOS). On the first view CDP seemed not to work at all between the two. After configuring both switches to CDP version 1, the SG300 recognizes the 2948G in "sh cdp neigh", but not vice versa:
core-switch> (enable) sh cdp CDP : enabled Message Interval : 60 Hold Time : 180 Version : V1 Device Id Format : Other core-switch> (enable) sh cdp neighbors No entry found.

I checked a similiar setup of an SG300 against an Catalyst3550 in the lab. this worked flawlessly.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
