Indirect Discovery
- Viktoryia Varapayeva (Deactivated)
NetMRI supports indirect partial discovery of otherwise unreachable virtual device contexts. A minimal subset of information is gathered by NetMRI, consisting of the following:
- Device type
- Uptime
- Vendor
- Model
Cisco devices supporting CLI access through the physical host will also allow the collection of the configuration files.
This information is entered into the NetMRI database. A full discovery of any virtual device context requires SNMP access. On Cisco virtual devices for Cisco ASA, Pix, ACE load balancers, and Nexus switches, SNMP access is available only to each virtual device context. As noted SNMP access to Juniper virtual device contexts is done indirectly through the SNMP activation on the virtual host, acting as a proxy for the VDCs.
Note
If virtual devices on a specific virtual host do not provide direct access through SNMP, you will see a warning message on the virtual device's Device Viewer, nothing that CLI interaction is the only supported communication mode.
