Enhanced vPC Testing
Enhanced vPC Testing
I have been working since long in DC Environment with Nexus Switches along with UCS, Never got a chance to setup a Lab and explain some config.
some of Live Environment, we are not allowed to do some test.
Finally Eve-NG is a good Gui for DC lab testing, and now it support to LACP on N9K and Server Side.
Cisco has a good documentation to understand vPC
https://www.cisco.com/c/en/us/products/collateral/switches/nexus-5000-series-switches/design_guide_c07-625857.html#_Toc271759485
EVE-NG have nice platform to test some features – can be download Lab below Link :
