Hello,

I have a Nexus 1010 with a VSM and NAM deployed. All work fine but i see "Dropping received frames from duplicate VSM saddr" logs. My Nexus 1010 is deployed in type 3 uplink mode. Ethernet 1 connect to port gi0/1 and ethernet 3 connect to gi0/5. I use the vlan 903 for management (UCS, Nexus1010, VSM and NAM) and 52 for control and packet

This is my Nexus 1010 configuration

virtual-service-blade VSM-1

  virtual-service-blade-type name VSM-1.1

  interface control vlan 52

  interface packet vlan 52

  ramsize 2048

  disksize 3

  numcpu 1

  cookie 1456780936

  interface data vlan 903

  ramsize 2048

Whats the domain id of the 1010 and the VSM that you deployed?

If you made them the same thats the problem.

You get that error message when the VSM sees another VSM on the same control vlan with the same domain id. The 1010 uses very simlar code to the VSM so if the domain ids are the same you will see that error message.

Hello,

You are rigth, i have the same domain id in Nx1010 and VSM. how i change it?. Is better change VSM or Nx1010 domain?.

Regards.

If you have a single 1010 the easiest thing is to change the domain id on the 1010. Since you are not seeing odd cluster issues I'm going to assume you only have one 1010.

The command should be

n1010v-AV(config)# svs-domain

n1010v-AV(config-svs-domain)# domain id #

If you have 2 1010s in a cluster and you already have hosts attached to the VSM running on the 1010s its going to be more involved.

Hello,

I have two Nx1010 in cluster, i have changed the VSM domain id without problems and the error is fixit.

Thank you very much.

Regards.

Thanks for the post... I ran across this as well and was a bit stumped!

Hi erfernandez,

How did you change the domain ID in VSM. Can you cnange other parameter like mgmt IP/ control vlan ID/ packet vlan ID ?
