I have a pair of 1000v VSM running version 4.2(1)SV1(5.2)
The ESXi host is configured with 2 uplink connecting to 2 different switch.
Using port channel mac pinning.
i configured Network State tracking (NST) with default timer. and repin action.
but when i put "switchport trunk allowed vlan none" on the upstream switch facing the host,
the NST status said it is split.
but the VMs connected is not repin to other uplink.
is there any other misconfiguration that i miss? or my NST verification is wrong (though, the status is showing network is split)?
Hello Ivan! It seems that we have the same problem. But here we have two channels, one with MAC and another with HM. Another people had configured the channel with MAC pinning and I can see that it is using another VLAN to track interfaces. Do you know how I can change tracking VLAN on NST?
The below whitepaper has instructions on changing the VLAN for NST on page 6 for individual ESX hosts if needed.
By default Nexus 1000V chooses the lowest forwarding VLAN ID that is allowed on the uplink port-profile. You can choose and configure a low-id VLAN (say, 4) suitable for tracking. You have to remove all lower-id VLANs from the trunk:
