Stacked N4064F Uplink to Meraki MX250
Hi all,
We need to uplink two stacked N4064F to a Cisco Meraki MX250. Our current plan is to connect a single port from each N4064F to the MX250 for redundancy/fault-tolerance. The MX250 doesn't support LACP, and it also doesn't support any type of STP, so we need to ensure that only one of the two links is up/forwarding at any time
Is it better to rely on STP on the stacked N4064F or should we use a link dependency group instead?
The thought with link dependency is to put a port from each N4064F into a link-dependency group, with action up set to make one port down when the other is up and vice-versa.
STP seems to be the more traditional method, and STP is recommended by Meraki, but I wanted to know how Dell's "inverted link dependency" would compare in this scenario.
All help appreciated!

Hi,
I think either method would work fine. STP should be easier and lower resources on the switch to maintain though. Let us know if you have any other questions.

Thanks Josh,
That's the info I was after.
Do you have any info on why link-dependency has higher resource use than STP? If it makes any difference, we're planning on using RSTP-PV with only a single 'transit' VLAN on the two uplink connections from the N4064F stack to the MX250.

Hello @ai_dd,
I was unable to find some white papers to provide you with some official information. But I guess it is because normally STP has lower resources because it is a more easy configuration and maintenance.
Regards.
