Inventory Discovery
Subchassis discovery inspects SNMP MIBs for the following configurable objects:
• MGX 8260 Chassis and Status
• MGX 8260 Card Configuration and Status, including SCC, NCC, BSC, and DMC cards
• MGX 8260 Line Configuration and Status, including DS1, DS3, SONET, Fast Ethernet, and
D channel
• ISDN Configurations, including Dlsap Profile and Macsap Profiles
• Backhaul Session Configurations, including Sets, Groups, and Sessions
Upon completion of subchassis discovery, Cisco MGM adds the subchassis components to the site
hierarchy display. You can expand the hierarchy to display cards and profiles by clicking the + sign next
to the MGX 8260 icons. Similarly, you can expand the hierarchy to display lines by clicking the + sign
next to each card. A number next to the MGX 8260 object indicates the number of contained cards or
lines.
The SCC contains either SONET or Fast Ethernet lines. The NSCs contain Dsx1or E1 lines. The BSCs
contains Dsx3 lines, which may be channelized for Dsx1 lines. DMCs contain Dsx3 lines that map to
NSC Dsx1 lines.
Manual Initiation of Subchassis Synchronization
You can manually invoke the subchassis syncup process from the pulldown menu of Cisco EMF GUI.
The subchassis discovery process retrieves subchassis component information from each Cisco
MGX 8260 Media Gateway and displays corresponding objects on the user interface.
To synchronize subchassis components, follow these steps:
Step 1 Log on to Cisco EMF. The Cisco Element Manager Framework Launchpad screen opens.
Step 2 Click the Viewer button. The MapViewer screen opens.
Step 3 Expand the tree of objects to display the list of MGX 8260 sites and nodes.
Step 4 Right click the desired site or MGX 8260 node; then click Open SubChassis Sync Up. The SubChassis
Sync Up screen opens.
Step 5 Select the desired MGX 8260 nodes from the list.
Step 6 Click Start Sync Up.
The system synchronizes the user display with subchassis components.
Periodic Subchassis Synchronization
Periodic subchassis synchronization discovers the subchassis components of each Cisco MGX 8260
Media Gateway without user intervention. This background task runs on a fixed interval, once every 24
hours, rather than at a fixed time. Therefore, the time of day when this task runs depends on the last time
the Cisco MGM controller was initialized.
