Can someone please assist in recommending the best method of configuring a vPC Network with Spanning-Tree.Earlier Design documents recommend running Bridge Assurance between Nexus switches.A more updated document (March 2013) recommends Not running B...

I have a requirement to enable Loop Prevention methods to a pair of UCS switches.We had a situation where a server was incorrectly configured to bridge its two interfaces, causing a loop back towards the network and causing severe impact.We urgently ...

We have a pair of N7K distribution switches connected to a pair of N7K Aggregation switches.We run vPC on both pairs of n7k's.n7k-d1 has two interfaces in a Port-Channel connecting to n7k-a1 & n7k-a2. (PC1)n7k-d2 also has two interfaces in a Port-Cha...

Hi again,Yes, the HSRP config stays the same.You could leave the VPC config as it would make it simpler to migrate. It would also allow both Core switches to act as Gateway's for traffic routed out of your Cores.You're also correct regarding the Leaf...

Hi Belray,I hope I can explain this sufficiently.You'll need to remove the VPC config off the Interfaces connecting from the 7K Spine to the 5K Leaf and configure them as "Switchport mode FabricPath". You'll however keep the Global VPC config on the ...

This is possible, however under what circumstances do you want to do this?Between the FabricPath Spine and FabricPath Leaf you're no longer running VPC.This is now a FabricPath Link and no VPC is configured there anymore.VPC+ is suppoed to be on your...

Yes, this is possible.If one of the Links fails, the traffic will be switched through the VPC Peer-Link.It's not recommended to have Data traffic over the Peer-Link, but if it's only under failure conditions that's fine.

Hi, you're correct sorry.The L1 and L2 is connected between the two 6100 switches and two of the other ports were used for uplinks.I've managed to arrange for a test UCS system for our Lab and will test the configuration and connectivity their.I'll c...
