Host/Server runs in Active/Standby on a vPC vlan?

[TCAM]

Sorry, i don't have Nexus gears to test it out.  

Is it possible for a host/server runs in active/standby (not port-channel) on a vPC vlan?  

Or host/server runs in active/standby mode has to be running in a non-vPC vlan?  

Thanks

When you say "active/standby vPC vlan" you mean HSRP or VRRP active/standby?

sorry, my bad, I was not clear on my previous post. 

I meant a server/host is running in active/standby mode (not port-channel) in vPC vlan.  Is it possible?  Thanks

As long as the server is configured with HA, you can just connect the uplinks from the server to 2 switches using regular trunk or access ports (no vpc or Portchannel).  This way when one link is active and the other one is stand-by.

Thanks Reza!  Let's take this discussion one level deeper.

Let's say the active link is up on vPC Secondary peer and standby link is up on Primary vPC peer.  Assuming that if peer-link fails, all vpc member ports on Secondary peer will shutdown but non-vpc port will remain in up and up state, so we will need something to trigger HA to failover. 

Do I need "vpc orphan-port suspend" command to trigger HA to failover if peer-link is failed? 

Thanks

Hi Joe,

I have never tested this in a lab before, but I think you need the "vpc orphan-port suspend" command configured on both primary and secondary switch.

Thanks Reza! 

As you can tell, I am setting up vPC for active/active and non-vPC for active/standby devices in a vPC domain.  Just curious, in a real life scenario, do you allow non-vPC vlans over peer-link?

Thanks
