Configuring Slow Packet Forwarding Engine Alarm

On an M Series, an MX Series, a T Series, or a SRX Series router, the Packet Forwarding Engine might not send a resource acknowledgment message to the Routing Engine within a predetermined time of 360 seconds. This delay in receiving resource acknowledgment could be due to a slow or stuck Packet Forwarding Engine on the M Series, MX Series, T Series, or SRX Series router, or on one of the LCCs connected to a TX Matrix, TX Matrix Plus, or TX Matrix Plus router with 3D SIBs.

Starting with Junos OS Release 13.2R1 (also applicable in Junos OS Releases 12.1R6, 12.2R5, 12.3R3, 13.1R2 and later), to display the issue as an alarm in the show chassis alarms command output and to append the alarm to the system log messages file, you must enable the slow Packet Forwarding Engine alarm on the router.

The following sections provide more information about the slow Packet Forwarding Engine alarm:

Enabling Slow Packet Forwarding Engine Alarm

To enable the slow Packet Forwarding Engine alarm, perform the following steps:

Note

By default, the slow Packet Forwarding Engine alarm is disabled.

  1. In configuration mode, go to the [edit chassis] hierarchy level:
  2. Enable the slow Packet Forwarding Engine alarm by configuring the slow-pfe-alarm statement.

Disabling Slow Packet Forwarding Engine Alarm

To disable the slow Packet Forwarding Engine alarm, perform the following steps:

  1. In configuration mode, go to the [edit chassis] hierarchy level:
  2. Disable the slow Packet Forwarding Engine alarm by deleting the slow-pfe-alarm statement.

Verifying That the Alarm Output and System Log Messages are Updated

Purpose

To verify that the output of the show chassis alarms operational mode command and the system log messages file are updated with the slow Packet Forwarding Engine alarm when:

  • The slow-pfe-alarm statement is enabled in the [edit chassis] hierarchy.

  • The Packet Forwarding Engine resource acknowledgment is not received by the Routing Engine within a predetermined time of 360 seconds.

Action

To check the output on an M Series, MX Series, T Series, or a SRX Series router:

  1. Verify that the alarm is displayed in the output of the show chassis alarms operational mode command.

    show chassis alarms

    user@host> show chassis alarms

    For field descriptions, see show chassis alarms.

  2. Verify that the alarm is appended to the system log messages file.

To check the output on a TX Matrix, TX Matrix Plus, or a TX Matrix Plus with 3D SIBs router:

  1. Verify that the alarm is displayed in the output of the show chassis alarms operational mode command.

    show chassis alarms

    user@scc> show chassis alarms

    For field descriptions, see show chassis alarms.

  2. Verify that the alarm is appended to the system log messages file.

Meaning

The output of show chassis alarms operational mode command and the system log messages file are updated as expected when the slow Packet Forwarding Engine alarm is enabled and when the Packet Forwarding Engine resource acknowledgment is not received by the Routing engine within a predetermined time of 360 seconds.

User-Defined Alarm Relay Overview

The ACX Series router alarm contact port—labeled ALARM on the front panel—allows you to manage sensors and external devices connected to the router in remote unstaffed facilities.

Note

Alarm contact port is not applicable on ACX5048 and ACX5096 routers.

Alarm Contact Port

The ACX Series router alarm contact port is a 15-pin D-type dry contact connector for alarms. The alarm contact port is used to generate LED alarms on the router and to turn external devices on or off. You can connect up to four input alarms and two output alarms. The alarm setting is open or closed.

Alarm Input

Alarm input provides dry contacts to connect to security sensors such as door or window monitors. The alarm input—open or closed—is sensed and reported to the management software. You can configure up to four alarm input relay ports (0 through 3) to operate as normally open or normally closed, and to trigger a red alarm condition or a yellow alarm condition or to ignore alarm conditions.

Alarm Output

Alarm output provides dry contacts to connect to external equipment, such as an audible or visual alarm that switches on or off–for example, a bell or a light. The four alarm output relay ports—0 through 3—are set up as follows:

  • Ports 0 and 1—These ports can be configured to trigger an alarm when the system temperature goes to the red alarm status and when an alarm input port is triggered.

  • Ports 2 and 3—These ports are not configured. They are used to indicate system major and minor alarms and are normally open. When a condition triggers an alarm, an alarm message is displayed.

To view the alarm input and output relay information, issue the show chassis craft-interface command from the Junos OS command line interface.

Configuring Chassis Alarm Relays

On ACX Series routers, you can configure alarm relays that can trigger alarms and turn external devices on or off. For example, if the router heats up to more than the critical temperature, the output port is activated and a device connected to the output port—such as a fan—is turned on.

To configure conditions that trigger alarms, include the relay statement with the input and output options at the [edit chassis alarm] hierarchy level.

The following output shows an example configuration of a chassis relay alarm:

Configuring Chassis Alarm Input

The ACX Series router alarm contact port—labeled ALARM on the front panel—allows you to manage sensors and external devices connected to the router in remote unstaffed facilities. You can configure up to four alarm input ports (0 through 3) to operate as normally open or normally closed, and to trigger a red alarm condition or a yellow alarm condition or to ignore alarm conditions.

To configure an input alarm:

  1. Configure the input port:

    For example, to configure input port zero (0):

  2. Configure the mode in which the input alarm is not active:

    For example, to configure open mode:

  3. Configure the trigger to set off the alarm:

    For example, to set off the yellow alarm:

  4. Verify the configuration with the show command:
  5. Commit the configuration with the commit command.

To view the alarm input relay information, issue the show chassis alarms or show chassis craft-interface commands from the Junos OS command line interface.

Configuring Chassis Alarm Output

The ACX Series router alarm contact port—labeled ALARM on the front panel—allows you to manage sensors and external devices connected to the router in remote unstaffed facilities. You can configure up to two alarm output relay ports (0 and 1) to operate as normally open or normally closed, and to trigger an alarm when the system temperature goes to the red alarm status and when an alarm input port is triggered.

Note

Ports 2 and 3 are not configured. They are used to indicate system major and minor alarms and are normally open. When a condition triggers an alarm, an alarm message is displayed, and the corresponding LED turns on.

To configure an output alarm:

  1. Configure the output port:

    For example, to configure output port zero (0):

  2. Configure the trigger to set off the alarm:

    For example, to set off the alarm when the system temperature goes into the red status:

  3. Verify the configuration with the show command:
  4. Commit the configuration with the commit command.

To view the alarm output relay information, issue the show chassis alarms or show chassis craft-interface command from the Junos OS command line interface.
