We're in the process of installing our first ACI fabric, and will be deploying all of our ToR leaf switches in vPC pairs, numbering the switches in each pair with even/odd numbers to enable us to group them into different maintenance groups.The valid...
I have a pair of N7Ks which have a number of HP Virtual Connect (VC) equipped enclosures attached via LACP.The N7Ks insist on LACP Slow timeout, and the VC on Fast timeout.For details:http://h30499.www3.hp.com/t5/HP-BladeSystem-Virtual-Connect/Change...

Scenario:- 3750 stack with two switches- each 3750 has an uplink to a different N7K- two N7Ks running vPC towards the 3750 stackWhen Master in 3750 stack reloads failover occurs to the member switch as expected.When that occurs the N7K with the link ...
Background:Present MPLS backbone based on 3750ME and 6504/Sup32 to all main locations.Rigid (and stable) structure at each site with C - CE - PE, eBGP pr. VRF between CE and PE, static/HSRP between C and CE.C typically 6500/Sup720, CE either 3560(G) ...
What is the purpose of Po51 / Po4051 and why is it not a vPC when you're running the switches in vPC+ mode?My guess from the log messages would be that you haven't configured "spanning-tree pseudo-information" such that the FP cloud is the root for a...
Why not simply use FabricPath to interconnect them instead?You avoid the concerns about routing across the interconnect that might arise with vPC, whilst maintaining the use of all redunant links for forwarding, and you get the rapid convergence of I...
