It's just the initial configuration, I anticipate using at least 2 more once the environment is stable.

It's just the initial configuration until the environment is stable. We plan to have at least 3 VLAN's total on day 1.

Thanks for the suggestion but it doesn't work for me. If I leave the port-channel set to on the switch ports stay up but the virtual switch ports bounce about every 5 minutes.

Try removing the config from the port channel interface and see if that keeps your etherchannel up.

I have the same type setup, but my configurations are on the physical ports and not the etherchannel. I'm running a 3750 though, and my etherchannel connects to an AIX server.

As in my previous post, I don't have anything configured on the etherchannel interface. Adding the physical ports to the channel group is enough to bring the etherchannel up.

Thanks, I wasn't sure if that was what you meant. I'm trying that now.

Hi Roland,

Are you connecting to HP blades using virtual connect by any chance?

I had a similar problem, solved by switching on lacp. I also had to keep the port channel (and all its members) shutdown whilst the ESX host booted up. Once the host had started I did a no shut on all the ports.

I saw your post when I searched before making this post. No I'm using an IBM server as the host and when I used lacp it didn't work. I tried both passive and active and neither worked. When I set the channel to "on" the ports transition to an up/up state on the 4500 but the ESX seems to intermittently lose it's connetions.

Thanks for your suggestion though. I will try to reboot the ESX while my ports are shut down and see if that helps.

ah, okay!

Only other thing I could suggest is to go through the VMWare hardware compatibility list very very carefully indeed.

ESX is very sensitive to things like firmware revisions on nic's etc.

Good luck.

Kevin
