4000m connected switches

Marcus Durden — Mon, 23 Mar 2009 12:07:36 GMT

I am new to my company and taking over the network for world domination, but I hit a snag in my master plan. With Cisco they have cdp to discover connected switches and such. But I am unfamiliar with HP switches. We have some scatter around and I would like to know if there is something I can use with HP switches to discover other devices connected like HP or Cisco switches and how do I use this great power.

Marcus, HP Procure switches use LLDP (Link Layer Discovery Protocol) to discover neighbour devices.

If you use ProCurve Manager Network Management solution(http://www.hp.com/rnd/products/management/index.htm), it can simply the discovery of your network since it uses other techniques, in addition to LLDP, to discovery and map your network topology.

4000M uses CDPv1, not LLDP

How do I use cdp from the from the command line? I don't see any options from inside The options are very limited.

To connect to the command prompt I go to Diagnostics > Command Prompt, the prompt that I see it SWITCH NAME:. When I do a help I do not see an options for CDP or LLDP.

How do you enter config term? When I enter config term I just get the system config.

Does the HP ProCurve Switch 4000M not support these commands?

Make sure you have latest firmware(http://www.hp.com/rnd/software/j4110930.htm). The release note for the C.9.30 firmware contains details on how to view/modify CDP configuration.

You can access them via the "menu" interface. Type "menu" and select (3) Switch Configuration> System Information
