Cisco Nexus Series HA

[Thushan Pramod]

Hi,

What is the equivalent feature to the stacking when it comes to Cisco Nexus? Is it VPC?

[Mark Malone]

Sort of yes nexus ha is VPC feature , you build a VPC domain between the 7ks or 5ks with fexes connected that are linked to both 5ks/7ks  with a crossbar between them , the 5ks / 7ks then act as one logical unit like stacking switches but its a different type of feature

Hi Mark,

So when it comes to Nexus 9k.

Is it possible to bundle more than 2 devices into same vpc domain?

What is the bandwidth?

port count in VPC?

Does Stacking is only for catalyst series? Is it not supported in nexus right?

Hi

stacking is not supported on nexus switches at all

if you want to know what a 9k is capable of check the data sheet , each model is different in what they can do they range in throughputs features etc depending on the model you chose

here is the link to compare the 9k models , you can see what each type os capable of

usually the design is only 2 nexus per vpc design like screenshot but you could interlink vpc domains but I have never done it we follow standard practices , not sure why you would need more than 2 , multiple linecards and resiliency involved in 2 chassis
