Userlevel 1
Hello,

Under Cumulus. Is it have concept about clustering two Cumulus devices?

My plan is Clustering two switch with Cumulus OS. Each host Ethernet connecting with individual switch running with LACP. It is used to active-backup once either one of switch have problem.

Thanks!

Sounds like you're talking about Multi-Chassis Link Aggregation (MLAG). MLAG is fully supported in Cumulus Linux. Check out our docs on the topic here: https://docs.cumulusnetworks.com/display/DOCS/Multi-Chassis+Link+Aggregation+-+MLAG

Thanks and checking now.

How about if I need trunking with our non Cumulus switch? Is that I just need create a bridge which including all multi VLAN and switch on STP?

Thanks!

Yes. To do any kind of Layer 2 feature (like VLANs or VxLAN) you need to create a bridge. STP is on by default in bridges for Cumulus Linux 3.0+ but for v2.5 you'll still need to enable it on the bridge with the "bridge-stp on" keyword.
