Linking 2 Aruba switches without stacking cables

    Hi all, newbie here looking for some assistance.

    I have 1 x Aruba 2390M (48 port version) switch which is almost full capacity. I've purchased a new 2930M (24 port version) and plan on linking the switches together to expand the scope of available ports in my building.

    Switch 1 (Original) has 5 VLAN's configured (including vlan 1 default) 

    Switch 2 (New) has the same 5 VLAN's created (including vlan 1 default)

    To link the switches, do I just need to physically connect the 2 (e.g. use port 5 on both switches) then untag port 5 on the default VLAN on both switches & tag port 5 in all VLAN's on both switches?

    Networking isn't my strong point sorry!

    Yes that is going to work. Tag all the VLANs on port 5 that you need to have on both switches and for VLAN 1 you can leave it untagged if you're using it.

    If you want to have a bit redundancy for the inter-switch link you can configure trunk (a bundle of multiple interfaces):

    trunk 5,6 trk1 lacp​

    This would bundle ports 5 and 6 to a single logical link. And then you would add the VLANs to trk1 interface.
