Comware

Dear,

I would like to inquire about the IRF stacking compatibility between two models of HPE FlexFabric switches. Specifically, is it possible to stack an HPE 5945 2-slot switch with an HPE 5945 4-slot switch?

I have reviewed the available documentation but could not find a clear statement regarding the compatibility between these two models. Could you please confirm whether stacking between these switches is supported? If possible, I would also appreciate any relevant technical documentation or guidelines.

Thank you in advance.

Laetitia.

From IRF support matrix:

Switch Series:                                        5945
Maximum devices in IRF domain:       10
IRF link capacity:                                    Must use 40/100GbE links
Max Physical Ports per IRF-Port:          8
Notes:                                                       Only works within 5945 switch series.
Number of active links per agg. group: Up to 32
Number of agg. group:                            Up to 1

You can combine 2-slot and 4-slot switches in the same IRF. You can't mix different switch series in IRF.
