A couple of questions:
1)If I have 6- Campus Mgr servers setup to discover different network ranges, can I use the single server sign on feature to login to one server and see all discovered devices?
2) If so, when using the User Tracking utility and 6- servers, will the end user still need to know which of the 6- servers the end host they are searching for would be discovered on or will it query all 6- servers and return the results?
1. No. SSO will allow you to authenticate once, then login to each server in the domain, but it will not aggregate all of your devices. Assuming you have configured DCR master/slave, each Campus Manager will feed one consolidate DCR server which is replicated on each of the slave servers. While this won't allow you to see one unified Topology Map in Campus, you can login to the DCR master server, and see all managed devices under Common Services > Device and Credentials > Device Management.
2. UT will be separate for each server. There is no aggregation.
