M5300 going to M4300 .... info on stacking with 10G and leaf/spine
We have an old M5300 stack which has no 10G ports for me to uplink servers, Storage and multigig Wifi nodes.
Also the nodes are now end of line as per the 2016 Transitiion document.
The old M5300 stacking notes said it must be same make & model.
I believe M4300 allows a mix of models..
Is there any guidance on how to stack M4300 1G access switches ports on M4300-52G+POE units
along side an M4300 offering 10G ports for servers etc...
The leaf/spine diagram in the transition note is interesting, but i want more info... where to go ?
also anyone know if Netgear offer a buy-back or replacement loyalty discount ...?
((Cisco are offering me cash to jump ship))

- Hi BaldwinA
Thank you for your message, I'm the Product Line Manager for M4300 (and their M4300 ancestors). Yes, you would greatly benefit from a mixed 10G/1G stacking topology using latest M4300 models.
You can review the models available and download the datasheet here: www.netgear.com/m4300
Under the Models tab, the 1G and 10G models are all there.
Under the Resources tab, the datasheet will let you understand spine and leaf stacking, we have good diagrams in the applications section.
Any 10G port can be used in Stacking mode on any model. Up to 4 10G ports simultaneously on each 1G model. Up to 16 10G ports simultaneously on each 10G model. This lets you build a variety of spine & leaf or matrix topologies to meet your 1G/10G requirements.
Of course NETGEAR is happy to sweaten your transition with a special discount. Feel free to send me a private message and I'll connect you with our expert Sales team.
Hope this helps,Laurent,
Thanks for detailed prompt response....was hoping you would pick this up.
Q> If I use 2 * 10G ports to uplink, the presumeably these are a type of LAG and delover 20G uplink bandwidth ?
Q> If as per the leaf/spine diagram, I use 2 *10G to one spine and 2*10G to another spine, I will have 20G to each core right ?
On the issue of licensing... is there any seperate licensing concern for the units,
or am I entitled to full functionality when i buy the unit and no further purchase required.

Hi,
Let me answer your questions. Also you can be in touch with an Expert Sales Engineer at NETGEAR locally, if you give me your contact details by Private Message, I will have you in touch with a NETGEAR good contact in your country. OK?
Uplinks and LAG: yes, you can form a LAG comprised of several ports across a stack, we call it distributed LAG, and you can use an algorithm based on L2, L3 or L4 source and destination, or a combination, to parse the traffic across your LAG.
Stacking links are not a LAG, they behave differently running stacking code. But the result is the same as they are parsing the traffic across switches using source IP address parsing algorithm for all packets.
In a spine and leaf stacking topology, absolutely you will get 20G bidirectional (so 20G in and another 20G out) between each leaf switch and each spine switch when you 2x10G stacking links to the left spine and 2x10G stacking links to the right spine.
There are no software licenses for M4300 series, you are entitled to the full functionality.
I hope this helps,
