4.2.4 Network Element Discovery
The Cisco MGM discovery service collects information from individual NEs; discovers new NEs;
updates network-level information (such as physical topology); and updates device-level information
(such as inventory and alarms).
Note The Discovered Network Elements group can only be viewed by SuperUsers and NetworkAdmins in
cases where all NEs are assigned to them.
The discovery process starts when a new NE is added to Cisco MGM. When discovery completes, all
information associated with the NE (such as inventory, configuration, and physical topology) is collected
and updated in Cisco MGM. By default, periodic, routine discovery occurs every 24 hours, beginning
from the time the Cisco MGM server starts.
NE
Properties
NE ID Allows you to enter a unique name for the NE in the form of an ASCII text string.
Apostrophes (') and quotation marks (“) are not accepted. The NE ID you enter should
be the same as the NE ID that is configured on the NE itself. If it is not the same, this
field will be updated with the NE hostname.
Note Do not use “MGM” as an NE ID because the Alarm Browser might contain
Cisco MGM alarms with the source ID “MGM.” It will be difficult to
distinguish between NE alarms and Cisco MGM alarms if they both have the
same source ID (“MGM”). For the same reason, do not cause Cisco MGM to
automatically populate an NE whose NE ID is “MGM.”
Note If the NE ID field is left blank, it will default to the IP address. After
communication is established, Cisco MGM discovers the NE ID from the NE.
Operational State Allows you to specify the operational state of the NE. There are three states:
• Under Maintenance—The NE is temporarily under maintenance but requires
monitoring.
• In Service—The NE is currently deployed and requires monitoring.
• Out of Service—The NE has been marked Out of Service and does not require
monitoring.
SNMP Community
String
Allows you to enter the SNMP community string for the NE. By default, the SNMP get
community string is public and SNMP set community string is private.
NE Service Level User
Name
Allows you to enter the user name. The default is cisco.
NE Service Level Pass
Word
Allows you to enter the password. The default is cisco.
Description Allows you to enter a description of the NE.
