Etherchannel in ESX 4 issue.

[Rohail2004]

We configured our Cisco 4948's switches with Etherchannels, and then I can't ping my VM's from vSphere host... Any suggestions?

our config

s3(config)#int port-channel1

s3(config-if)#description for NICs

s3(config-if)#int gi0/23

s3(config-if)#channel-group 1 mode on

s3(config-if)#int gi0/24

s3(config-if)#channel-group 1 mode on

What mode do you have the vSwitch set in under Load Balancing on the NIC Teaming Tab?

What does a show etherchannel display? Have you tried a shut/noshut on the etherchannel interface?

I agree with rohail2004. Edit your vSwitch, click on NIC teaming, change load balance to Route based on ip hash.

What shows up when you run show etherchannel load-balance from you switch? Does it match what is on your virtual switch. You will need to set route based on IP hash. You will also need to add this to switch config for Route based on IP hash:

Port-channel load balance src-dst-ip (Enables IP load balancing)
