Nexus 1000v Layer 3 mode Primary and Secondary VSM communication problem.

egorospe07
Level 1
Level 1

I have a HA Pair setup and everything works fine when both my primary and secondary VSMs are on the same host.  However,   when I migrate either of my VSMs to another host  Communication is lost.

Both hosts are on the same subnet and is able to ping each other.  Subnet is 10.20.0.0/16

Any help would be much appreciated..

I also receive this message on my primary VSM:

%VEM_MGR-SLOT5-1-VEM_SYSLOG_ALERT: sfswitchdata : L3 Control and System VLAN configurations not applied on vethernet port. VMware Port[83886108] DVPortGroup[dvportgroup-36347]. L3 Control can be applied only on VMKernel port.

Show module on my VSM produces this output:

The capability L3 control setting is only for use on the port-profile that the VSM <--> VEM vmk.

You would need a second port-profile to put the VSMs on (all 3 interfaces on them can go in the same port-profile in L3 mode). Just be sure to set the vlan that it's set to as a system vlan.

Hi,

Is your vCenter server using port-profile mgmt as the Network? I'm assuming your vCenter is a virtual server as well?
