Thank you.
You are righjt, it looks this is Arista:
HP-2530-48G
Just a question that bothers me with tagging untagging vlan system.
Imagine this command on port 24 for example: switchport trunk allowed vlan 10,20,30,40,50,60,70,80,90,100,110,120,130...
How would you discover which vlans are on this trunk with the Arista method?
You could go vlan by vlan and check if its tagged on port 24. Obviously it's not a great method if you have hundreds or thousands vlans on one inteface (I work for a large ISP and we have huge trunk links for example).
