this is a simple guide to enable the loop-protect feature on your Hpe/Aruba switch.
Connect to your cli and issue this command :
As you can see it’s disabled.
Now we can enable it per port or per vlan basic… anyway , the way that i prefer is per VLAN and, after that , we need to choose which physical port is on it
So now we enable per VLAN mode with this command:
loop-protect mode vlan
For example we can enable it on vlan 1 and 3 ..
As we can see, it’s enable only vlans 1 and 3
At this point, we have to assign the loop-protect on a port basics . In our case we have an 2530 with 48 port and so, this is the command:
loop-protect 1-48 receiver-action send-disable
Now we are ready to testing it…
This is my magic looping cable!
Now we can check what’s happened with the command..:
And we can see that port 29 is now detected and blocked.
