Stack question and LACP

Good morning everyone.

 

First of all I admit that I never configured a HP switch, I worked with Cisco so I'm not really familiar with HP's switches.

 

Here's the overview:

 

I installed 4 switches to one of our customer (HP ProCurve 2810 - 3 x 48p + 1 x 24p) FW: J9022A. They don't use VLANs.

 

Now the first switch has Uplink to a Dell switch (don't blame me...) - 1 cable. Then each switch is directly connect with the first switch with one cable. Nothing special has been configured (except the forced speed+duplex).

 

The switch with the uplink is the commander in the stack and the others are joined.

 

STP + flow control is DISABLED.

 

Now my questions:

 

1) When I configure a STACK in cisco's devices, I can control everything on the other switch. The most important thing is that I can access the other ports... is it possibile with these HP's switches?

 

2) I want to configure LACP but in this way:

sw#1 - port 24 + sw#2 - port 24 + sw#3 - port 24 + sw#4 - port 24 IN THE SAME trunk (actually I think that for HP a TRUNK is an aggregate of many ports...) that goes to the DELL switch configured with port aggregation too.

 

I now I can do this with cisco, I can configure port-channel on multiple ports of differents switches, but I don't know if I can do the same with HP.

 

My tought is / was to add each port of each device to the same TRUNK 1 + LACP and then plug them to the other switch, but i'm not sure...

 

 

Thank you very much for your time.

No, you can't do any of those things with the 2810, or really any other ProCurve/E-series switch other than maybe the new 3800.

What you're looking for is a Cisco Stackwise equivalent, in HP this is called IRF and are only available on the ex-H3C switches (A-series).
