Hi Experts,

I have some switches from HP.
Please can you explain the stacking from switches ?
Because I dont know if my switches are stacked or not.

Under Stack Management I see members down and up.

A "stack" is a group of physically different switches that are managed as if they were a single switch.

Typically they are connected to each other using special ports and cables.

As Giltjr stated, if you don't see any special cables connecting the switches in the rear, they are most likely not stacked. They won't look like ethernet cables, but more like thick printer cables. Hope that's a good comparison.

I wonder if your HP-switches are Procurves .
The ones I own only use the stacking term for a single IP managing multiple switches in same subnet.
"Under Stack Management I see members down and up"
Could be a Member has become detached from the stack. A possible cause is an interruption to the link between the Member and the Commander.
If you specify the HP's then the experts could provide more precise info.

Yes we have ProCurve switches = 4208vl

But I think they are not stacked with the special cable in the back.
They are connected over the right fibre ports.
This means not stacked, right ?

This means they are connected to each other.
How you call this ?

Yes, they are just uplinked to one another, not stacked.

"ProCurve Stack Management (stacking) enables you to use a single IP address and standard network cabling to manage a group of up to 16 total switches in the same IP subnet (broadcast domain)."
Please refer to chapter 13 in ftp://ftp.hp.com/pub/networking/software/6400-5300-4200-3400-AdvTrafficMgmt-Oct2006-59906051.pdf
Hope this will clarify what HP-procurve stacking or "stacking" is.
