Dual homed FEX configuration

Hi,

 

Have a question on dual homes FEX's

I have a FEX that's dual homed to 02 Nexus 5K'S

Lets say my FEX is 150 and if I want to configure port 150/1/1 to vlan 100, do I need to login to both Nexus 5K's and configure the port 150/1/1 to vlan 100?

OR Can config sync help

 

Thanks

stan

This is the wrong forum for this topic, but I'll assist.

Without configuration sync enabled, you would have to configure both Nexus 5K exactly the same for the FEX port before traffic will forward.

Configuration sync would help you in only having to configure it once, but I have had mixed results using configuration sync so I tend not to use it in my deployments.

I agree with jjohnston.

Cisco tells me config-sync is better than it used to be but I haven't given it another go since some early issues with it.

In either case the configs have to match.
