So, this may be a dumb question, but one that has always bugged me. When creating an LACP trunk in an ERS switch, you need the lacp key XX command. I've always just entered it to get things working, and not thought much of it. But why do we need it? What does it do? Why don't other switch brands require some identifier like that to create lacp trunks on their end? What would happen if i didn't enter it?
If there's some documentation out there anyone can point me to, or an explanation anyone can give, it would be much appreciated.
Thanks!
