LACP or Trunk? Urgent advice needed

[fiza]

I have 2 HP Procurve 5412zl switches. I have 2 x 1GB fibre links between them which I would like to aggregate to double the bandwidth. On looking at the port configuration I can see that there is "trunking" and "LACP" available. My understanding is that a "trunk" in HP terms means an aggregated link but then there is also an option for LACP.

How would I configure the ports so I get a 2GB pipe between the switches? No VLANs here.

Set them as LACP trunks.

You can use either static trunks or LACP it makes little difference switch to switch but I've always used static HP trunks myself

So leave the LACP disabled as in the picture?

Also how do you know if its working as an aggregated link?

[Tallwood_6]

No you need to set the ports on one switch that is part of the LACP as active and the ports on the other switch as passive although active both ends will work.

You should see traffic going down both ports on the switch if its working ( look at the port counters)

Are you able to get in to the console of the switch. I cant remember off the top of my head what the command is but ive got it set on some of my 2530, one of my 4104gl and my 4204vl. Edited July 25, 2014 by timbo343
