Calculating up-link bandwidth requirements between switches

matthew.norman

Hello all,

Is anyone able to advise if there is a standard or recommended calculation for working out how much bandwidth/speed you need between two connected switches.

For example a stack of 3 48 port gb switches to a another stack of 2 48 port gb switches?

I understand the method of calculating the stack back plane requirements but not the switch to switch connections themselves.

Appreciate any help.

Matt

Hi Matt,

There is no standard or spesific document stating how much bandwidth needed for uplinks. It really depends to your environment and the applications you are using.  Usually one or 2 10Gig uplinks are sufficient per switch or even per stack of 2 or 3 switches. So, in your case you can create a Portchannel between the stacks and put 2 10Gig in it.  In the future if you need more bandwidth you can add more physical interfaces to the Portchannel very easily without any downtime.
