Establishing a 20GB connection between two 10GB switches
Establishing a 20GB connection between two 10GB switches
You're working with an ArubaS2500-48P and need to connect two switches via a 20B link using a USW-Aggregation setup. You've already tried a few times but had trouble. More details would help—please share what you've tried so far and any specific symptoms or errors. Thank you!
Configure a link aggregation on both ends' 10GB ports. If your switch lacks 10GB ports, you may not succeed.
I've attempted but encountered issues when switching them off, as each switch has a unique brand. The setup varies slightly per switch, which might be causing confusion.
I remember you mentioned that besides setting up the LAG, each port might require certain settings like link speed, duplex, trunking, VLANs, and possibly the LAG it connects to. Could you share the configurations you've applied on each switch? Also, do you currently face a bottleneck with a 10G connection, or is there a particular reason for using a LAG?
i set up lag on each tweet using the right ports, but i lost internet on the switch after trying. i had to reset it so it works again. now the internet comes from the Arbua switch, and i get a 20gb link between my backup server and my device. i’m not sure if the lag was for uplink or trunk, and i’m worried about adding another 10gb link without issues. i just want to make sure it works smoothly on most computers in the network.
When setting up the LAG, for Aruba the ports should be set as trunks. The steps mentioned likely involve creating a bridge aggregation group, assigning ports to that group with trunk configuration, and specifying which VLANs are allowed through. There’s guidance available on HP’s documentation for configuring LAG via CLI for Aruba devices, and similar instructions probably exist for Unifi as well. It seems the issue might stem from a mismatch between VLANs or port types—access instead of trunk—and that needs clarification. I’m only guessing, but it looks like the internet connection could be dropping due to incorrect VLAN or port settings.
I included a screenshot of the sections you believe are necessary for the Arbua switch.
