Hi,
I am having difficulty implementing what should be an easy task.
I have a single ESXi 6.5U1 host with 2 NICs teamed in a single vSwitch. The load balancing is set to “route based on IP hash”. As part of my troubleshooting I have also disabled beacon probing (Net.MaxBeaconsAtOnce=0).
The NIC team connects to a single Cisco 2960 switch. Both interfaces are up and the host is reachable.
To avoid Mac flapping on the switch (due to the NIC teaming), I am trying to configure an Etherchannel on the switch. My config below (both switch ports are configured identically):
interface GigabitEthernet0/6
switchport trunk native vlan 1000
switchport mode trunk
channel-group 2 mode on
end
interface GigabitEthernet0/7
switchport trunk native vlan 1000
switchport mode trunk
channel-group 2 mode on
end
interface Port-channel2
switchport trunk native vlan 1000
switchport mode trunk
end
EtherChannel Load-Balancing Configuration:
src-dst-ip
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
2 Po2(SU) - Gi0/6(P) Gi0/7(P)
The post channel comes up on the switch but the ESXi host is not reachable. As soon as I shut one of the ports, the comms is restored. I can’t figure out what I am doing wrong – any ideas?
Thanks
