Nexus 5000 Series...Impact of changing Port Type

[qutub.siddiqui]

Hi All,

I am looking for help in production scenario of Cisco Nexus 5000 Series switches hanging as peer and connected to other nexus, 6500 pairs in etherchannel config.

Just read the best practices from cisco and found there shouldn't be "spanning-tree port type network " over trunks uplinks/downlinks going to other Nexus switches configured as vpc's to avoid BA. Instead there would be "normal" option need to be use.

"Network" would be aplicable to only vpc peers link switches.

My question is, what impact does this change of spanning port type will have on production switches. As critical services are running we are cautious doing do.

Any advises and expert opinions please.

Regards.

Hi,

"spanning-tree port type network" is only used for vPC peer links that runs between the 5ks.

I would recommend having an outage window to do this, as you need to apply this command on both switches and most likely you will see a short disruption while the mode is changing.

HTH

Good Luck
