show vlan and sorting

[Antonio_Prado]

Hi,

could be possible to make EXOS sort VLANS by VID?

currently it sorts just by name and in case of hundreds vlans it's pretty annoying.

show vlan | sort VID
show vlan sort VID
thank you

If you have EXOS 15.6.1 or later, then you could use python scripting.
There doesn't seem to be a way to attach the script file so I've included it below with before and after console output.

Hey Antonio

Yes you are correct and we are working to make new advancements on how the VLANs are created and indexed. I believe 16.1 will provide more focus on VLAN ID numbers.

Scripting provides a way for us to manipulate the OS to provide benefit in a faster perspective versus waiting for a new version of code. It also provides a way for customer to re-write what they see on the screen. If for example you want to capture data from two different screens and show them on with one command then we can accomplish it with scripts.

The Python scripts also allow us to run them as an application on the switch so that as soon as the switch is booted the script is loaded into XOS.

I hope that helps explain the reason for scripting and how it can provide benefit between versions of code

Thanks
P

hi dave,

that's useful.

generally speaking, a basic sorting task on vlans shouldn't require programming skills, though

thank you
