Scott … with regards to the commands for ESX/ESXi, in your experience setting ESXi that way out outline above will allow for both listen and advertise. Also, you are talking about ESXi 4.0 correct?

Mike, I just logged into an instance of the vSphere Management Assistant (vMA, next-generation VIMA) and ran “vicfg-vswitch —help” (that’s two dashes in front of help) and it clearly shows the option to use either -B or —set-cdp (again, that’s two dashes in front of set-cdp). I’ve used it many times to set the CDP status on a vSwitch on both ESX and ESXi.

Hope this helps!

Scott,
I must be missing something in this CDP command for exsi because I don’t see where the -B switch is available or anything is referenced about –set-cdp. I am running the command using RCLI and I can’t get anything back. If I run the command to just list the config info I have no issue so I’m connecting to the correct ESXi server. Any quick tips on what I’m doing wrong is greatly appreciated.

Shawn,

No, the commands are correct. It is not required to use “-Bboth”; putting a space in there (as in “-B both”) works just fine. The long form of the “-B” command is “—set-cdp” (WordPress sometimes mangles dashes, so that should be double-dash followed by set-cdp). So, in the first example I’m using the long form, and in the second example I’m using the short form. Use “esxcfg-vswitch -h” to view the parameters for more information.

Might want to look at your commands I believe that they are wrong. the switch should be -Bboth, you are missing it from one and have a space in the other.

[...] couple of weeks ago I wrote about enabling Cisco Discovery Protocol (CDP) on next-gen ESX/ESXi and made the comment that I hadn’t yet found a way to view CDP data from the ESX side. One of [...]

I would recommend against sharing information, we are still getting traffic that is pretty specific about it being in NDA as yet. They will release it in due time, why risk it?

I think it’s ok to post about things that were shown at VMworld Europe: either talked about in a public session or available in the labs. This is a bit of configuration wonkery, doesn’t seem to spill many beans, and I assume this was talked about in the labs at VMworld.

That’s a fuzzy line, and I don’t know how that helps if you weren’t at VMworld. I do trust folks in the beta to be reasonable, and I’d counsel on being conservative, but ultimately, VMware created this situation by showing the product in public on one hand while asking beta testers to be private on the other. Certainly bugs in the beta, suggestions, or other surprises should stay in the private discussion.

I’m pretty sure NDA has not been lifted as I just got an e-mail yesterday regarding NDA and beta info.

Is the NDA lifted yet? I don’t recall getting any notices and I would love to share some info.
