Hi Guys
what is the best configuration betwen vmware ESX server with 10 Physical NIC card and cisco 6500 , This ESX Server host 12 vm with VLAN 100,150.200
THANKS

For previous installations I used a L2 trunk on a static port-channel between the ESX server and the upstream distribution switch (usually a stack)
Without knowing too much about your design:
you could change your load balancing on your vswitch to IP-hash-based load balancing and make sure you configure your 6500 the same way -
port-channel load-balance src-dst-ip
As long as VLAN tagging is enabled on your vswitch you will have one logical trunk.
I think the limits on active ports on your 6500 will be 8 so ensure you use 8 physical NICs on your ESX server. The other 2 NICS could be used for management and vMotion.

Hi Scott
Pls post me sample config for that 8 interfaces!
thanks

Example config (off the top of my head so check your own syntax)
Assuming your 6500 isn't running CatOS:
conf t
int range G1/1 - 4
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk allowed vlan (your VM related VLANs)
switchport trunk native vlan (use another VLAN here not configured on your vswitch - doesn't support native vlans)
channel-group 1 mode on
!
int range G2/1 - 4
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk allowed vlan (your VM related VLANs)
switchport trunk native vlan (use another VLAN here not configured on your vswitch - doesn't support native vlans)
channel-group 1 mode on
port-channel load-balance src-dst-ip (or TCP/UDP ports)
The above will configure 8 ports over 2 I/O modules into one L2 port-channel, note vswitch doesn't support LACP so the channel-group is configured statically with the on command.

Hi Scott
what if i didn't configure the below command, does the port-channel wont go up???
switchport trunk native vlan 999
thanks

If you didn't configure the native vlan it would default to VLAN 1, which isn't a recommended practice
It's best to create a native VLAN on your L2 domain for this purpose.
The main thing to look out for is not using the native VLAN on your vswitch, as vswitch doesn't support non-tagged frames.
Also ensure all your interfaces are configured identically which are members of the same port-channel.
