Hello,

I have been trying to place a VMWare ESXi Server on a portchannel port 
connected at Gigabit.

The Server is a IBM eSeries, with 2 Gigabit Ethernet, and is connected to a 
Cisco 6500 with a 48 GigabitRthernet Module.

All other configurations I have work fine, and the servers worked on Gigabit 
nicely when they had Windows installed on them, so I do think it really is a 
ESXi problem

(I tried both in auto-negotiation and forced speeds... works fine at 100Mb, 
doesn't go up on Gigabit...)

Has anyone had trouble with installing ESXi and the ports not working on 
Gigabit?

Thanks,

Nuno

You do know that GBE uses all 4 pairs in a
CAT5/6/whatever cable while lower speeds only use
2 pairs? Maybe you have a duff cable?

Yep... I checked that already, and it does happen on all 4 of the ports I'm 
trying to configure... :(

I'm wondering if it�s possible that somehow the ESXi only lets the ports go 
up on 100...

I also tried to uplink one of them to a ASA 5000 port, and it behaved the 
same way... and with the same cables, with Windows 2003 Server it went up 
fine at Gigabit... :(

I'm really starting to think it's a ESXi problem.. will probably have to 
check it better next week... :/

Thanks for the tip though :)

Nuno, ESXi fully supports Gigabit Ethernet (and 10 Gigabit Ethernet), 
so I doubt that the problem lies with ESXi. I personally have done it 
more times than I can count with a variety of servers and switches.

Have you checked the Hardware Compatibility List for VMware ESXi 
against the hardware that's in your server?
