Configuring SNMP

If you prefer, you can use a third-party SNMP manager, such as HP OpenView, to monitor system health. The system supports SNMP v2c and SNMPv3.

To configure the SNMP agent:

  1. Select System > Log/Monitoring.
  2. Click the SNMP tab to display the SNMP configuration page.

    Figure 1 shows the configuration page for Access Control Service.

    Figure 2 shows the configuration page for Secure Access Service.

  3. Complete the configuration as described in Table 1.
  4. Save the configuration.

Guidelines

MIB File

Use the Juniper Networks MIB file link to download the device management information base MIB) file. You add this file to your SNMP manager configuration.

SNMP Version

Select your SNMP server version:

  • v2c
  • v3
Agent Properties

SNMP Queries

Select to support SNMP queries.

SNMP Traps

Select to send SNMP traps.

System Name

Specify a system name.

System Location

Specify a location.

System Contact

Specify a system contact.

Community String

  • Required only for SNMPv2c.
  • To query the system, your network management station must send it the community string.
  • To stop the SNMP system, clear the community field.
SNMPv3 Configuration

Username

Specify the SNMPv3 username. The User-Based Security Model (USM) is the default Security Module for SNMPv3. The system supports only one user at a time to be registered with an SNMP engine. Editing the SNMPv3 user attributes overwrite any already registered SNMPv3 user. The SNMPv3 user must have read-only access on all MIBs supported by the system. SNMPv3 user configuration attributes can also be used for SNMP traps.

Security Level

SelectionAuth ProtocolAuth PasswordPriv ProtocolPriv Password

No Auth, NoPriv

Auth, NoPriv

Select MD5 (HMAC-MD5-96) or SHA (HMAC-SHA-96).

Enter an authentication password. The password can contain any ASCII characters and must be at least 8 characters in length.

Auth, Priv

Select MD5 (HMAC-MD5-96) or SHA (HMAC-SHA-96).

Enter an authentication password. The password can contain any ASCII characters and must be at least 8 characters in length.

Select either CBC-DES or CFB-AES-128.

Enter a privacy password. The password can contain any ASCII characters and must be at least 8 characters in length.

Trap Thresholds

Note: Setting a threshold value to 0 disables that respective trap.

Check Frequency

Specify the frequency in seconds for sending traps. The default is 180 seconds.

Log Capacity

Specify the percent of log space used. The default is 90%.

Users

Specify the percent of user capacity used. The default is 100%.

Physical Memory

Specify the percent of physical memory used. The default is 0 (not reported).

Swap Memory (Virtual Memory)

Specify the percent of swap memory used. The default is 0 (not reported).

Note: We recommend you monitor swap memory to alert you to potential memory issues. The threshold for traps for physical memory usage might be reached even if the system is not experiencing any difficulties.

Disk

Specify the percent of disk utilization. The default is 80%.

CPU

Specify the percent of CPU utilization. The default is 0 (not reported).

Meeting Users

Specify the percent of meeting users. The default is 100%.

Optional Traps

Critical Log Events

Send traps when the system logs critical events.

Major Log Events

Send traps when the system logs major events.

Save SNMP Settings?

Click Save Changes to update the SNMP agent configuration. The page is refreshed and displays the SNMP engine ID. If the configuration is changed to move from SNMP v2c to SNMP v3, the system generates and displays two engine IDs.

SNMP Servers

Hostname / IP address

Specify the hostname or IP address for the SNMP servers to which the system will send any traps it generates.

Port

Specify the port for the SNMP server. Typically, SNMP uses port 162.

Community

Specify the community string (if necessary).

Keep the following configuration tips in mind when you configure your SNMP manager to listen for this SNMP agent:

  • Add the Juniper Networks MIB file to the SNMP manager configuration.
  • If using SNMPv2c, the community string configuration for the SNMP manager and SNMP agent must match.
  • If using SNMPv3, the SNMPv3 user configuration for the SNMP manager and the SNMP agent must match.
  • If using SNMPv3, you must specify the Authoritative Engine ID for SNMPv3 traps that was generated when you saved the SNMP agent configuration.

Table 2 is a reference of MIB objects for Juniper Networks IVE systems. Some objects apply only to Secure Access Service.

Table 2: MIB Objects

Object

Description

logFullPercent

Returns the percentage of available file size filled by the current log as a parameter of the logNearlyFull trap.

signedInWebUsers

Returns the number of users signed in through a Web browser.

signedInMailUsers

Returns the number of users signed in to the e-mail client.

blockedIP

Returns the IP address—blocked due to consecutive failed login attempts—sent by the iveToomanyFailedLoginAttempts trap. The system adds the blocked IP address to the blockedIPList table.

iveCpuUtil

Returns the percentage of CPU used during the interval between two SNMP polls. This value is calculated by dividing the amount of CPU used by the amount of CPU available during the current and previous SNMP polls. If no previous poll is available, the calculation is based on the interval between the current poll and system boot.

iveMemoryUtil

Returns the percentage of memory utilized by the system at the time of an SNMP poll. The system calculates this value by dividing the number of used memory pages by the number of available memory pages.

iveConcurrentUsers

Returns the total number of users logged in.

clusterConcurrentUsers

Returns the total number of users logged in for the cluster.

iveTotalHits

Returns the total number of hits to the system since last reboot. Includes total values from iveFileHits, iveAppletHits, meetingHits, and iveWebHits.

iveFileHits

Returns the total number of file hits to the system since last reboot.Incremented by the Web server with each GET/POST corresponding to a file browser request.

iveWebHits

Returns the total number of hits by means of the Web interface since last reboot. Incremented by the Web server for each http request received by the system, excluding file hits, applet hits, and meeting hits.

iveAppletHits

ivetermHits

Returns the total number of terminal hits to the system since last reboot.

logName

iveLogFull

The log file (system, user access, or administrator access) specified by the logName parameter is completely full.

Note: When SNMP traps are enabled, the iveLogNearlyFull and iveLogFull traps are sent when the log files are 90% full and 100% full respectively, even if the threshold is set to 0 (disabled).

iveMaxConcurrentUsersSignedIn

Maximum number or allowed concurrent users are currently signed in. You can configure this trap to be sent at any percentage. To disable this trap, set the Users trap threshold to 0%. The trap’s default value is 100%.
