Hey,
So been seeing the -E switches appear in our inventory lately and been rolling a few out. Run into an "
So normally- when I say normally I mean I've never been put in this scenario so I hope someone may know.
Can you run a 9372-E and 9372
and to take it further.. unlike the Arista where MLAG refuses to bring the peer
Thanks,

Hi,
vPC peering an E switch with a non-E switch should not be an issue.

"The Cisco Nexus 9372PX-E is a minor hardware revision of the Cisco Nexus 9372PX. Enhancements in the hardware are transparent in Cisco® NX-OS Software mode and offer feature parity."

Having said that: BE CAREFUL when pairing device into a vPC pair. I once tried putting a 5548UP and a 5596UP together into a vPC pair, it was unstable and actually managed to cause a ripple effect throughout the datacenter, destabilizing other vPC pairs (even though the vPC domain IDs were different!!!).
vPC pair MUST be hardware matched, to a certain level. As part of the vPC startup process, CFSoE exchanges compatibility information either over the peer link (or over FabricPath in a N7k / N5k "vPC+" scenario) to verify you won't break things. The Nexus 9372PX and 9372PX-E are *probably* sufficiently close that they would have no issues (the -E thing relates to enhanced ACI features, since you're asking vPC I know you're talking NX-OS mode).
Is it a supported mechanism? Hard to say. Is it a god idea? No.
