Configuring SNMP with Quick Configuration

J-Web Quick Configuration allows you to define system identification information, create SNMP communities, create SNMP trap groups, and configure health monitor options. Quick Configuration Page for SNMP shows the Quick Configuration page for SNMP.

To configure SNMP features with Quick Configuration:

  1. In the J-Web user interface, select Configure>Services>SNMP.
  2. Enter information into the Quick Configuration page for SNMP, as described in Table 147.
  3. From the SNMP Quick Configuration page, click one of the following buttons:

Table 147: SNMP Quick Configuration Summary

Field

Function

Your Action

Identification  

Contact Information

Free-form text string that specifies an administrative contact for the system.

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

System Description

Free-form text string that specifies a description for the system.

Type any system information that describes the system (J4350 with 4 PIMs, for example).

Local Engine ID

Provides an 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.

Type the MAC address of Ethernet management port 0.

System Location

Free-form text string that specifies the location of the system.

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

System Name Override

Free-form text string that overrides the system hostname.

Type the name of the system.

Communities

Click Add.

Community Name

Specifies the name of the SNMP community.

Type the name of the community being added.

Authorization

Specifies the type of authorization (either read-only or read-write) for the SNMP community being configured.

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

Traps

Click Add.

Trap Group Name

Specifies the name of the SNMP trap group being configured.

Type the name of the SNMP trap group being configured.

Categories

Specifies which trap categories are added to the trap group being configured.

  • To generate traps for authentication failures, select Authentication.
  • To generate traps for chassis and environment notifications, select Chassis.
  • To generate traps for configuration changes, select Configuration.
  • To generate traps for link-related notifications (up-down transitions), select Link.
  • To generate traps for remote operation notifications, select Remote operations.
  • To generate traps for remote network monitoring (RMON), select RMON alarm.
  • To generate traps for routing protocol notifications, select Routing.
  • To generate traps on system warm and cold starts, select Startup.
  • To generate traps on Virtual Router Redundancy Protocol (VRRP) events (such as new-master or authentication failures), select VRRP events.

Targets

One or more hostnames or IP addresses that specify the systems to receive SNMP traps generated by the trap group being configured.

  1. Enter the hostname or IP address, in dotted decimal notation, of the target system to receive the SNMP traps.
  2. Click Add.
Health Monitoring

Enable Health Monitoring

Enables the SNMP health monitor on the device. The health monitor periodically (the time you specify in the interval field) 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

Select the check box to enable the health monitor and configure options. If you do not select the check box, the health monitor is disabled.

Note: If you select only the Enable Health Monitoring check box and do not specify the options, then SNMP health monitoring is enabled with the default values for the options.

Interval

Determines the sampling frequency, 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 an interval time, in seconds, between 1 and 2147483647.

The default value is 300 seconds (5 minutes).

Rising Threshold

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 (the default), SNMP generates an event when the value of any key indicator reaches or exceeds 90 percent.

Enter a value between 0 and 100.

The default value is 90.

Falling Threshold

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 (the default), SNMP generates an event when the value of any key indicator falls back to 80 percent or less.

Enter a value between 0 and 100.

The default value is 80.

Note: The falling threshold value must be less than the rising threshold value.
