VRRP

[mcvosi]

I currently have two MS250's in a stack, but I am needing to create two port mirrors for analyzing traffic. Since there is a limitation of one mirrored destination per switch stack I am thinking of VRRP. Can the stack ports still be used, or do I need to use an SFP?

Here you can read the overview about MS warm spare.

You can't use the stacking ports no - you'll need to use a standard link (or two, as a LAG) between the switches.

The SFP+ slots obviously provide the best options for high-capacity between the two - maybe using DAC:    MA-CBL-TA-1M   (3M also available).    Full list here:   https://documentation.meraki.com/General_Administration/Cross-Platform_Content/Small-Form_Factor_Plu...

you could also just use some copper ports and some patch leads, if high capacity (10 Gbps+) between the switches isn't necessary.

Make sure your STP setup, in terms of root bridge, matches your VRRP config.

I take it that, by two port mirrors, you mean two different destination ports for mirrors?

Yes, two destination port mirrors.
