You can use the Enterprise Device Manager (EDM) to manage the system using different Virtual Router Forwarding (VRF) contexts.
Using the GlobalRouter (VRF 0), you can manage the entire system. GlobalRouter is the default view at log in
Using a VRF context other than the GlobalRouter (VRF 0), you have limited functionality to manage the system. For instance you can only manage the ports assigned to the specified VRF instance
Specify the VRF instance name on the EDM screen when you launch a VRF context view. You can use the context names (SNMPv3) and community strings (SNMPv1/v2) to assign different VRFs to manage selected components, such as ports and VLANs. For more information about context names and community strings, see Simple Network Management Protocol (SNMP).
