Network device system properties

For discovery on SNMP devices, Discovery devices uses the community string or SNMP credentials.

SNMP Credentials

Discovery explores many kinds of devices, such as switches, routers, and printers, using the SNMP protocol. Credentials for SNMP do not include a user name, just a password, which is the community string. The default read-only community string for many SNMP devices is public, and Discovery will try that automatically. Enter the appropriate SNMP credentials if they differ from the public community string.

System properties

You can configure many aspects of Discovery to work according to your personal preferences. The following properties apply to network routers and switches. To view the properties, navigate to Discovery Definition > Properties unless indicated otherwise.
Table 1. System Properties for Network Routers and Switches
Property Description
glide.discovery.L3_mapping Provides a logical mapping of the TCP/IP layer for network gears, starting in Fuji. This is not Layer 2 mapping,
  • Type: string
  • Default value: true
  • Location: System Property [sys_properties] table
glide.discovery.max_concurrent_invocations_per_schedule Sets a maximum number of scheduled invocations of the same Discovery schedule, starting in Fuji. It prevents a backlog of scheduled runs if Discovery does not finish before the next invocation is scheduled to run. The value is an integer that represents the max number of automated invocations of the same schedule that may proceed at one time. If the limit has been reached, subsequent scheduled invocations are canceled. A value of 0 or any negative number disables this property.
  • Type: integer
  • Default value: 3
  • Location: Discovery Definition > Properties
