Hi All,
So I have a HP 5412zl Switch here at work and we're trying to get LACP links working to our site next door.
There are 2 fibre links to each of the 3 cabinets next door, each 10GbE
I have done the following on the core switch
trunk a6,c6 trk6 lacp
trunk a7,c7 trk7 lacp
trunk a8,c8 trk8 lacp
On the other side which are HP 2920G's
trunk 1/a1,3/a1 trk1 lacp
trunk 1/a1,3/a1 trk1 lacp
trunk 1/a1,2/a1 trk1 lacp
I have tagged them in all the vlans required and left them untagged in vlan 1 which is the management vlan.
However i am getting an issue, as soon as i connect the second link, spanning tree disables the trunk?
What command do i need to issue to add these trunks / interfaces to disable spanning tree on them and get them running at 20GbE?
