Chapter 5 Network Management
Inventory Discovery
Invoking Automatic Discovery
When you initiate automatic discovery, Cisco EMF pings each IP addresses in the given range. If a
response is received, it initiates an SNMP GET request for the enterprise object id (OID). If the OID
matches any of the predefined Cisco EMF Class mappings, such as MGX 8260, an object of that class
is created and displayed. If no mapping is found, the process creates a generic SNMP device under the
Physical level of the hierarchy. Generic devices can’t be managed.
To discover network elements, follow these steps:
Step 1 Start Cisco EMF.
<CEMF_ROOT>/cemf/bin/cemf session
Step 2 Log on to Cisco EMF. The Launchpad screen opens.
Step 3 Click the Discovery button. The Discover Network Devices screen opens.
Step 4 Configure the discovery parameters:
Step 5 Click Start.
Step 6 At the end of the discovery process, click Close.
Inventory Discovery
Subchassis synchronization searches for entities within a Cisco MGX 8260 Media Gateway and displays
them on the user interface. This process is automatically invoked after autodiscovery.
