Not sure if i understood the question correctly, you would like switch over from Active to Stanby and back it back to Active when active back ?

the switch over need to done manually, by reloading or force switch over. explain below as steps : (hope is that what you looking ?)

So i would know in Catalyst should choose the mode ( RPR, RPR+ or SSO) or it's a optional and there are another confige

Hi,

When you have 2 sups in a chassis, you want to configure them as SSO. This way, the failover is very fast. Once configured, verify with the command "show redundancy". One sup should be active and the backup sup should be in "hot standby" mode.
