Wired Intelligent Edge

Hi there I'm new to the IGMP configuration and wondering if anyone can provide some assistance or insight. I currently have a legacy LUXUL switch with a configuration that I need to copy onto an Aruba 6300m. Here is the config of the Luxul (the commands are similar to that of a CISCO/ARUBA switch)

I'd like to use vlan 1 in my config as well. Any assistance would be awesome. Thanks :)

The best way to get this done is to add snippets of configuration and see the behaviour and figure out to fix the issues along the way.

Reach out to your Partner/SE to see what your options are, if they can help with the configuration part.
