Two different switch

[Srna]

Greeting,

Please for help with connecting two switches

I have ARUBA 2920 with 2x 10GbE modules and now I want to connect with NETGEAR M4300-12X12F

I wonder which twinax cable should be used to make things work between these two switches

Thanks

Which type of interconnection (uplink) are you thinking about? LAG with 2 or more physical ports aggregated together on each side? if so which physical port have you considered (Optical? Copper? 1GbE? 10GbE?)? ...or just a single physical link (again: Optical? Copper? 1GbE? 10GbE?)?

Both - if correctly equipped [*] - have 10Gbps ports (through SFP+ with 10G Transceivers or 10GBASE-T copper ports) so it's a matter to plan which type of trunk you want to deploy with the physical ports both units are equipped with.

[*] The Aruba 2920 has these Modules for rear slots:

• HPE 2920 2-Port 10GbE SFP+ Module (J9731A)
• HPE 2920 2-port 10GBASE-T Module (J9732A)

Thank you for your reply

Aruba use 2x HPE 2920 2-Port 10GbE SFP + Module (J9731A) and I want to connect 2 ports agregation with NETGEAR M4300-12X12F (SFP + connection)

Actually, I'm interested in buying a switch that has 12 ports SFP+ for reasonable money.
HPE offers only extremely expensive devices and my job now not justify such investment.

If you want to deploy a 2x10Gbps Link Aggregation (LAG) with two optical ports you should, on both ends:

1. Equip each Switch with genuine, supported and compatible 10GbE SFP+ Transceivers.
2. On Aruba 2920 the above point (1) means that you have to directly install into the added Aruba 2920 2-port 10GbE SFP+ Module (J9731A) on the back slot two SFP+ Transceivers (using Link 1 and Link 2 ports): see QuickSpecs [*] to decide which 10G Transceivers type - SR, ER or LR - is better for your networking environment: it all depends on optical link distance between both Switches and also on Fiber Optic type (Multi-Mode 62.5/125um|50/125um or Single-Mode 9/125um, you should know that yet).
3. On Netgear M4300-12X12F (Model Number: XSM4324) you should have twelve SFP+ ports on left front side, so the point (1) means that you should equip the Switch with two 10G SFP+ Transceivers (AXM763 or AXM761 for MM, AXM762 or AXM764 for SM).
4. On each Switch, configure a LAG (Link Aggregation Group) made of two 10GbE member ports, then set the LAG to use the IEEE 802.3ad (LACP) for link aggregation (both Switches support that).
5. Be sure to cope Transceivers types on both ends: as example, if you have a 62.5/125um MM Fiber Optic link which is short enough (short = let's say below 220 meters) use two HPE X132 10G SFP+ LC SR Transceivers (J9150A) on Aruba 2920 side and two Netgear AXM763 Transceivers on Netgear M4300-12X12F side; those Transceivers have LC connectors and both support 62.5/125um MM Fiber Optic link.
6. Clearly if Fiber Optic main Link has different physical parameters (MM vs SM, lenght, core/cladding diameters, Connectors style on optical patch panels) you should adapt the 10G SFP+ Transceivers type to use on both ends (or, at best, play with Fiber Optic Patch Cables); Fiber Optic Patch Cables should be matched too (LC/LC or whatever) with the type of Fiber Optic Patch Panel used on each end.

[*] Read original updated documentation of Aruba 2920 and Netgear M4300-12X12F to understand specific hardware requirements/restrictions and to learn how to create a LAG with LACP on those Switches.
