Hi all,
I have stand alone Nexus 7018 switch which is connected with 2 ethernet cables to ESX host (VMware V-Sphere 4).
My goal is to create ESX host teaming for load balancing purposes between the N7K to the ESX host.
I created Port-channel on the N7K to bundle the 2 ports. On the ESX host I configured Teaming in the vSwitch.
After configuring, I had only partial connectivity. If I shut on of the physical ports in the Port-Channel (any of the 2), then everything works perfectly.
I though it might be a load-balancing issue on the Nexus or on the ESX host. I've tried every possible combination of load-balancing algorithms but nothing helped.
For troubleshooting purposes, I connected the same ESX host to c6500 instead of Nexus, configured the same Port-channel and everything worked perfectly!
I'm out of ideas here. Please help.
Nexus ports configuration:
interface Ethernet17/47
switchport access vlan 701
mtu 9216
channel-group 25
no shutdown
interface Ethernet17/48
switchport access vlan 701
mtu 9216
channel-group 25
no shutdown
interface port-channel25
switchport access vlan 701
mtu 9216
N7018# show port-channel summary
25 Po25(SU) Eth NONE Eth17/47(P) Eth17/48(P)
N7018# show port-channel load-balance
Port Channel Load-Balancing Configuration:
System: source-dest-ip-port
Port Channel Load-Balancing Addresses Used Per-Protocol:
Non-IP: source-dest-mac
IP: source-dest-ip-port
Nexus module type is: N7K-M148GT-11
NX-OS version 4.2(6)

I would have expected to this to work properly as well. Are you able to configure the port-channel to use LACP on each end? This way you can ensure the port-channel comes up as expected on each side?

Hi Chad,
Thanx for answering...
LACP isn't supported on vSphere4 vSwitch.
