5510 layer3 switch connectivity to 5520 layer 2 stack

5510 layer3 switch connectivity to 5520 layer 2 stack

5510 layer3 switch connectivity to 5520 layer 2 stack


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?

RE: 5510 layer3 switch connectivity to 5520 layer 2 stack

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.
