Table 106: SNMP Configuration Details

Field FunctionAction

Contact Information

Specifies the administrative contact for the system.

Enter any contact information for the administrator of the system (such as name and phone number).

System Description

Specifies the description for the system.

Enter any information that describes the system.

Local Engine ID

Specifies the administratively unique identifier of an SNMPv3 engine for system identification. The local engine ID contains a prefix and a suffix. The prefix is formatted according to specifications defined in RFC 3411. The suffix is defined by the local engine ID. Generally, the local engine ID suffix is the MAC address of Ethernet management port 0.

Enter the MAC address of Ethernet management port 0.

System Location

Specifies the location of the system.

Enter any location information for the system (lab name or rack name, for example).

System Name Override

Specifies the option to override the system hostname.

Enter the name of the system.

Community

Specifies the name and authorization for the SNMP community.

  • Click +.

  • Enter the name of the community being added.

  • Select the desired authorization (either read-only or read-write) from the list.

Trap Groups

Name

Specifies the name of the SNMP trap group being configured.

Enter the SNMP trap group name.

Categories

Specifies which trap categories to add to the trap group being configured. The options available are:

  • Authentication

  • Chassis

  • Configuration

  • Link

  • Remote operations

  • RMON alarm

  • Routing

  • Startup

  • CRRP events

Select an option.

Targets

Specifies one or more IP addresses that specify the systems to receive SNMP traps that are generated by the trap group being configured.

Click +, enter the target IP address for SNMP trap group, and click OK.

Health Monitoring

Specifies the option to check the SNMP health monitor on the device. The health monitor periodically checks the following key indicators of device health:

  • Percentage of file storage used

  • Percentage of Routing Engine CPU used

  • Percentage of Routing Engine memory used

  • Percentage of memory used for each system process

  • Percentage of CPU used by the forwarding process

  • Percentage of memory used for temporary storage by the forwarding process

Enable the option.

Interval

Specifies the sampling frequency interval, in seconds, over which the key health indicators are sampled and compared with the rising and falling thresholds. For example, if you configure the interval as 100 seconds, the values are checked every 100 seconds.

Enter a value from 1 through 24855. The default value is 300 seconds.

Rising Threshold

Specifies the value at which you want SNMP to generate an event (trap and system log message) when the value of a sampled indicator is increasing. For example, if the rising threshold is 90, SNMP generates an event when the value of any key indicator reaches or exceeds 90 seconds.

Enter a value from 1 through 100. The default value is 90 seconds.

Falling Threshold

Specifies a value at which you want SNMP to generate an event (trap and system log message) when the value of a sampled indicator is decreasing. For example, if the falling threshold is 80, SNMP generates an event when the value of any key indicator falls back to 80 seconds or less.

Enter a value 0 through 100. The default value is 80 seconds.
