Hi allI have an SQL server that is due to move to a new pair of Nexus 9000 leaf switches, with a VPC configured between them. The ports on the new switches are configured as LACP active, just like the other SQL servers, and when this move was first a...
Hi allI have a spine and leaf (non ACI) new setup and I am doing performance tests before it goes into production. My problem surrounds spanning tree and the time taken to converge when a link is disabled.The cores are not connected together but the ...
Hi allWe have remote access VPN setup via Cisco AnyConnect, terminating on the outside interface of the FTD. We also have a site to site VPN in place, from the FTD to a company, and one of the remote access users needs to connect via HTTPS to a serve...

All switches are running rapid pvst+What I also don't understand is this: Core 1 has been set as the root bridge by giving it a low priority. Why would any of the leaf switches choose the VPC link as its root port, with a cost of 2, when it has a dir...
