OS6900 virtual chassis switch keepalive link

[gsjh]

Hi. I have 2 OS6900 switch configured as virtual chassis. Can I know how to prevent split brain from happening? Can I use the EMP port on each switch to connect each other to setup a keepalive link?

There are two possibilities:
1. Remote chassis detection (RCD) via EMP. You only need to configure an ip address at any EMP and connect the EMP (in case of 2 f.e with direct cable - otherwise via a L2-switch).
2. Virtual chassis split protection (VCSP) via a helper switch (connected with a LAG to your vc). In the cli guide you will find the commands for both (vcsp and helper).
