LACP on 2510G-24

[mikeyb79]

Hello, I have a pair of 2510G-24 switches currently being used for MPIO iSCSI networking. 

There is very little configuration on the switches. Ports 13 - 20 on each have flow control enabled as required by Dell for the EqualLogic array. My VMware hosts are also plugged in to these ports. There's only two hosts with two iSCSI ports each and one SAN so it's pretty light on the port requirements, but no jumbo frames with flow control on these babies. Oh well.

The switches are connected to each other and configured as a "stack". They are connected to each other on Port 1. The recommendation is to use as many stack port as the array has active NIC ports (which is 2, since the PS4000E has two active GbE NICs enabled). I need to stack across another port to achieve this.

Can I use LACP and add Port 1 and, say, Port 3 to the link to accomplish this? Or is this a "trunk" in HP terminology (should I make a trunk and throw a couple ports into it to connect the two switches? Inter-switch links? 

Hope it's not more complicated than that, we were already mislead about simultaneous Jumbo Frames and Flow Control on these switches which has been a bit frustrating.

You have to configure a trunk to make a LACP between two switches. 

cli

2510G-24(config)#trunk 1,3 trk1 lacp

instead of lacp you can also use 'trunk' to create a static lag (link aggregation group)

use

[trunk help]  to see all possibilities

on interface level you can put 'lacp' in active or passive mode. use 'lacp help'

Wow, that's exactly what I needed. Much appreciated!
