Configure stacking - HP- A5120 El Switch

[Dan_Pinheiro]

Hi All...

I´ve configured two A5120 El Switch with a LSPM1CX2P interface card each one.

Everything works fine if I connect only 1 cable between the switches to build the stack.

If I connect 2 cables, using the two interface ports, stack doesn´t work.

Is necessary some additional configuration to enable this scenario? I would like to provide redundancy using both ports of interface.

I´ve already search for information, no success.

Tks.

how's your IRF config?

[Dan_Pinheiro]

No IRF config. Is it necessary?

Doubt about IRF: What kind of redundancy it provides???

IRF is the kind of stacking you shuld run on the 5120EI, it offers great resiliancy and redundancy.
