5510 layer3 switch connectivity to 5520 layer 2 stack

[ableseaman]

Afternoon

We have an Avaya ERS5510 switch running with advanced routing software connecting to our managed WAN.

We have a seperate Avaya ERS5520 stack (2 switches) so server a bank of servers.

The 5520 has a single trunk port (switch 1 port 48) connecting back to the 5510 (Port 24).

To add a little resilency into the set-up we want to add another trunk between the two switches - the 5520 will have a second trunk port (switch 2 port 48) connecting back to the 5510 (port23).

Is this as easy as simply settings up a trunk port at both ends or do I have to worry about potentially creating loops?

Configure two ports on the 5520 stack and two ports on the 5510 with the proper VLAN membership and tagging, then add them to a multilink trunk group. Thats all there is to it.
