Nesux FEX Active/Active Configuration

[gerardtorin]

Hi, I´m installing two 5672 switches and one 2232 Fex with Active/Active topology. It is the same config both switches with the Fex ports?

I Mean, Do I need to copy the same configuration both 5672 for Fex ports?

Thanks

Gerard

Hi,

When you say "Active/Active topology" you mean the fex connects to both 5672 switches? If yes, you need to have identical config on both switches.

Glad to help and good luck!

Just to clarify/expand what Reza noted, the two Nexus's FEX related configurations should be identical, but a small bit of it doesn't have to be identical (e.g. port descriptions).  (Of course, when it's not, it's great for causing confusion.)

Later Nexus IOS versions support a configuration option to keep sync'ed the critical parts between a Nexus pair.  You might want to skim: http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/operations/n5k_config_sync_ops.html
