The 1:1 redundancy mode is generally used to provide reliability for devices. In stacking scenarios, one active device and one standby device are deployed. If the active device fails and services cannot run properly, an active/standby device switchover is performed to ensure. Which's the best practice for stackwise when choosing the active and standby switches? Which's the best practice for stackwise when choosing the active and standby switches? 08-19-2020 12:29 PM Good day, I have the following topology (Stack switches are Catalyst 9k): Core A (g0/0)-- (g0/0) Stack 1. So there is a requirement for a modular chassis Core Switch with Redundant Active/Active processor. Hi, What do you need ? For modular chassis core, it will better to look 8400 or 6400 product ------------------------------. If you've just running VM traffic over the 2 NICs then you're better off using both as active. By means of the ClusterXL Control Protocol (CCP), the physical interface connected to the Virtual Switch is monitored.
