Hi Guys
I have a cluster of hosts and have been testing with one vm on one host for network failover
Basically, i have two physical switches with vpc's
My host has two nics connected to my test vds, there is one nic to each physical switch . IP hash enabled on the portgroup for vm testing - this all works ok and if i take down one side of the channel then i still have a ping
If i use explicit failver (should not be using this i know when vpc's) then as long as dvuplink1 is listed first and then dvuplink2 is listed second, then all is ok here too
The issue is when i switch the portgroup to use dvuplink2 first and dvuplink1 is listed underneath it then the vm wont ping UNLESS i take down one side (any side) of the port channel
Can someone explain to me why this is happening ?
Here is switch A
interface port-channel 111
description To Chassis1:Server1
switchport mode trunk
switchport trunk allowed vlan x x x
spanning-tree port type edge trunk
no negotiate auto
vpc 111
Here is switch B
interface port-channel111
description To Chassis1:Server1
switchport mode trunk
switchport trunk allowed vlan x x x
spanning-tree port type edge trunk
no negotiate auto
vpc 111
