Configuring Transmission Alarm Customization

Configuring Transmission Alarm Customization

This section describes the usage scenario, pre-configuration tasks, and data preparation for transmission alarm customization.

Usage Scenario

In the scenario where transmission devices are connected to IP devices, if the network is unstable, a large number of burr alarms will be generated. As a result, the physical status of interfaces on the transmission devices will switch between Up and Down. To enable IP devices to ignore these burrs, configure transmission alarm customization on the IP devices.

Pre-configuration Tasks

Before configuring the transmission alarm customization function, power on the Router and ensure that it is working properly.

Configuration Procedures

For the following configuration tasks (except for the configuration verification), perform one or more of the following configurations as required.

Configuring the Types of Alarms That Affect the Physical Status of Interfaces

Transmission alarm customization can be configured on interfaces or globally.Different interfaces support different alarm types.

Context

After alarms are generated on a transmission device, transmission alarm customization can be used to control the impact of the physical interface status. Configure the following commands globally or on the interface connecting to the transmission equipment.

The transmission alarm filtering interval can be configured globally or on the interface. The global configuration takes effect on interfaces supporting the function. The relationship is as follows:

  • When the alarm customization is configured globally, if the non-default alarm customization configuration exists on an interface, the configuration on the interface takes effect.
  • When the alarm customization is not configured on the interface, the global configuration takes effect.
NOTE:

The global configuration of transmission alarm customization is supported only on the Admin-VS.

Procedure

  • Configure transmission alarm customization globally.
    1. Run system-view

      The system view is displayed.

    2. Run transmission-alarm down { wan | pos } { auais | b1tca | b2tca | b3tca | lais | lcd | lof | lom | lop | los | lrdi | lrei | oof | pais | pplm | prdi | prei | puneq | rdool | rrool | sdbere | sfbere | trool } *

      The alarm customization is configured on 10GE WAN interfaces and on POS interfaces globally, which can cause interfaces to go Down.

    3. Run commit

      The configuration is committed.

  • Configure transmission alarm customization on interfaces.
    1. Run system-view

      The system view is displayed.

    2. Perform either of the following commands.

      • To enter the POS interface or 10GE WAN view, run the interface interface-type interface-number command.
      • To enter the specified ATM interface view, run the interface interface-type interface-number command.
      • To enter the specified CPOS interface view, run the controller cpos cpos-number command.
      • To enter the WDM interface view, run the controller wdm controller-number command.
      • To enter the CE1 interface view, run the controller e1controller-number command.
      • To enter the E3 interface view, run the controller e3controller-number command.
      • To enter the Trunk-serial interface or serial interface view, run the interface interface-type interface-number command.

    3. Perform either of the following commands:

      • To customize alarms that affect the physical status of POS or 10GE WAN interface, run the transmission-alarm down { auais | b1tca | b2tca | b3tca | lais | lcd | lof | lom | lop | los | lrdi | lrei | oof | pais | pplm | prdi | prei | puneq | rdool | rrool | sdbere | sfbere | trool } * command.
      • To customize alarms that affect the physical status of WDM interfaces, run the transmission-alarm down { odu-ais | odu-lck | odu-oci | otu-ais | otu-lom | otu-sd-ber | otu-sf-ber | pm-bdi | pm-tim | r-lof | r-los | r-oof | sm-bdi | sm-iae | sm-tim } * command.
      • To customize alarms that affect the physical status of CPOS interfaces, run the transmission-alarm down { los | lof | oof | lais | lrdi | lrei | b1tca | b2tca | b3tca | sdbere | sfbere | rrool | pais | auais | prdi | prei | lop | pplm | puneq | lom } * command.
      • To customize alarms that affect the physical status of ATM interfaces, run the transmission-alarm down { los | lof | oof | lais | lrdi | lrei | b1tca | b2tca | b3tca | sdbere | sfbere | rrool | pais | auais | prdi | prei | lop | pplm | puneq | lom } * command.
      • To customize alarms that affect the physical status of CE1 interfaces, run the transmission-alarm down { lof | los | pais | prdi } * command.
      • To customize alarms that affect the physical status of E3 interfaces, run the transmission-alarm down { lof | los | pais | prdi } * command.
      • To customize alarms that affect the physical status of Trunk-Serial or Serial interfaces, run the transmission-alarm down { pais | prdi | oof } * command.

      NOTE:
      • Not all interfaces support the preceding alarms because alarm types vary with hardware types. If the alarm type that the hardware does not support is configured, the configuration fails. The system will display a message telling you which alarm types are not supported on this interface.

      • WLNK alarms can be viewed only and cannot be configured by using this command. The WLNK alarms are always enabled and can cause the physical status of interfaces to go Down. The display transmission-alarm command can be used to view the status and statistics on wlnk alarms.

      By default, the LAIS, LOF, and LOS alarms can change interface status. If these alarms are disabled, service data cannot be forwarded correctly. Enabling the three types of alarms is recommended.

    4. Run commit

      The configuration is committed.

(Optional) Configuring b1tca, b2tca, b3tca, sdbere, and sfbere Alarm Thresholds

The b1tca, b2tca, b3tca, sdbere, and sfbere alarm thresholds can be configured. When an alarm reaches the threshold, it will be reported to the system.

Context

Perform the following steps on the interfaces that are connected to transmission devices:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

    10GE WAN ,POS ,ATM interfaces support the configuration of alarm thresholds.

    Or you can run controller cpos cpos-number to enter CPOS interface view.

  3. Run transmission-alarm threshold { b1tca b1tca | b2tca b2tca | b3tca b3tca | sdbere sdbere | sfbere sfbere } *

    The b1tca, b2tca, b3tca, sdbere, and sfbere alarm thresholds are configured.

    The alarm thresholds are in the format of 10-n. "n" is specified by an alarm parameter in the transmission-alarm threshold command. The value of sdbere must greater than or equal to the value of sfbere.

  4. Run commit

    The configuration is committed.

Verifying the Transmission Alarm Customization Configuration

After configuring transmission alarm customization, verify the configuration and check the alarm status and statistics on an interface.

Prerequisites

Transmission alarm customization has been configured.

The transmission alarm suppression function has been enabled using the transmission-alarm damping command.

Procedure

  • If an interface is a 10GE WAN interface, run the display transmission-alarm wan interface-number [ auais | b1tca | b2tca | b3tca | lais | lcd | lof | lom | lop | los | lrdi | lrei | oof | pais | prdi | prei | pplm| puneq | rdool | rrool | sdbere | sfbere | trool | wlnk ] * command to check alarm configuration on the interface.
  • If the interface is a WDM interface, run the display transmission-alarm wdm interface-number [ odu-ais | odu-lck | odu-oci | otu-ais | otu-lom | otu-sd-ber | otu-sf-ber | pm-bdi | pm-tim | r-lof | r-los | r-oof | sm-bdi | sm-iae | sm-tim ] * command to check alarm configuration on the interface.
  • If the interface is CE1, run the display transmission-alarm e1 interface-number [ los | lof | pais | prai ] * command to check alarm configuration on the interface.
  • the interface is a CPOS interface, run the display transmission-alarm cpos interface-number [ auais | b1tca | b2tca | b3tca | lais | lof | lom | lop | los | lrdi | lrei | oof | pais | pplm | prdi | prei | puneq | rrool | sdbere | sfbere ] *command to check alarm configuration on the interface.
  • If the interface is E3, run the display transmission-alarm e3 interface-number [ los | lof | ais | rai ] * command to check alarm configuration on the interface.
  • Run the display transmission-alarm threshold [ interface-type interface-number ] command to view the thresholds of b1tca, b2tca, b3tca, sdbere, and sfbere alarms on the interface.
