IP Auto Discovery of the Cisco Chassis

Auto discovery is the application that discovers existing Cisco 12000/10720 Routers, saving time and
effort.
The auto discovery window can be opened from the Viewer or Discovery icon in the Launchpad. For
further information, refer to the Cisco Element Management Framework User Guide.
The Auto discovery application has three mechanisms for discovering chassis:
•
•
•
Auto discovery can discover chassis on more than one subnetwork using multi-hop discovery. It can be
scheduled to run at preset times (the Cisco Element Management Framework User Guide details how to
set the schedules).
After the chassis is detected, an object representing the chassis is created and placed under the site from
which auto discovery was launched. A map of the chassis is also created, as shown in
page
Note If you wish to auto-discover a chassis that can be managed by Cisco 12000/10720 Router
Manager, then the Physical Path option must be enabled and an appropriate Physical Path
(terminated with a Site) must be selected. Provided this is done, the auto discovery
application will create a chassis below the selected Physical Path for each discovered
chassis.

This deployment procedure can be applied to the deployment of any of the generic objects
although all of the steps may not apply to the particular generic object that you are deploying.
IP—ICMP pings are used to find chassis in a given IP address range. This finds which IP devices
exist, but does not discover what kind of device they are.
SNMP—SNMP get requests are used to find chassis in a given IP address range. Several SNMP
community strings can be used so that equipment with different community strings can be
discovered in the same discovery session. The SNMP information returned by devices is used to
work out what kind of device has been found.
IP and SNMP—ICMP pings are used to find chassis and then SNMP requests are used to interrogate
the chassis to find out what kind of chassis they are. This is the default mechanism.
