Is there any tool or Command for comparing the VLANs from Two Switches?


Userlevel 1
I have Ten Switches but each having 200 or 300 VLAN's.
My Question is, What is the right way to compare two Switches (VLAN) ?
Is there any tools or commands for comparing those VLAN's ????
Because I want to check all the Switches and want to configure the Missing VLAN's..!!
Kindly help me out in this...!!!!!

Note : All are Extreme X450e-48p Switches.

Netsight has a config compare tool. This will show you what is added/deleted/changed between 2 different config. If you compare 2 different switches it will show a lot of other changes, but you can just focus on the VLANs. Please see Netsight Help -> OneView -> OneView Features -> Compare Device Configurations

ExamDiff is a Freeware Windows tool for visual file comparison. You could also try that..

Thanks Mr.Sumeesh.!!!
There are a lot of comparing tools available online. Just Google it.
Or, just paste a complete config of all your vlans on each switch... then they will be all up to date.

In my case , All the switches are live (Production)
Are you sure, it will not affect the live Switch ????
I don't want to take Risk by applying all the commands on Live Switches..!!!!! 😞
Am I right ????

Yes, it would affect the switches and it is not recommended to do it in a production environment.
First Edit the configurations as you wish and then paste it on the switches.
