Cisco Remote PHY Fault Management

This document describes how to configure the events for fault management on the Cisco cBR Series Converged Broadband Router.

Information About Fault Management

Fault management on RPD is required for remote monitoring, detection, diagnosis, reporting, and correcting the issues.

The Fault management module provides the following support:

  • RPD can send events to the CCAP core

  • CCAP core can get events from RPD

  • Send RPD events using SNMP traps

  • On the CCAP core, view log in to the CLI

  • SNMP poll events are supported

RPD Event Reporting

An RPD logs events, generates asynchronous notifications that indicate malfunction situations, and notifies the operator about important events. The RPD event reporting includes two methods of reporting.

  • During the initialization of RPD, CCAP core synchronizes events from the RPD.

  • During run-time operations, RPD notifies the CCAP Core of the events

Restrictions for Configuring RPD Events

Following restrictions are applicable:

A maximum of 1000 events are retained on Cisco cBR. The RPD retains 1000 events locally and 1000 events in pending state.

How to Configure RPD Events


Note

To know more about the commands referenced in this module, see the Cisco IOS Master Command List.

Configuring RPD Events

You can configure an event profile and apply it to RPD. Use the following commands to configure RPD events:
enable
configure terminal
cable profile rpd-event profile_id
  priority {emergency|alert|critical|error|warning|notice|informational|debug} {0x0|0x1|0x2|0x3}
  enable-notify

  • 0x0—No log

  • 0x1— Save log in RPD local storage

  • 0x2—Report to Cisco cBR

  • 0x3— Save log in RPD local storage and report to Cisco cBR

You must enable-notifications for the RPD to report any event to the Core.

Applying the Event Profile to RPD

Use the following commands to apply the Event Profile to an RPD:
enable
configure terminal 
cable rpd rpd_name
  rpd-event profile profile_id

Note

If RPD is online when changing the profile, reset the RPD, after you change the profile.

Enable RPD Event Trap

You can enable RPD event traps to send RPD events using SNMP traps. Use the following commands to configure RPD event traps:
enable
configure terminal
snmp-server enable traps rpd-event priority

Priority can be 1-8, where:

  • 1—Enable RPD event trap for emergency priority

  • 2— Enable RPD event trap for alert priority

  • 3—Enable RPD event trap for critical priority

  • 4— Enable RPD event trap for error priority

  • 5— Enable RPD event trap for warning priority

  • 6— Enable RPD event trap for notice priority

  • 7— Enable RPD event trap for informational priority

  • 8— Enable RPD event trap for debug priority

The priority higher than the selected priority is also displayed.

Configure SNMP Trap Server

You can configure SNMP trap server on the cable modem using the following commands:

enable
cnfigure terminal
Router# snmp-server host ip_address traps version 2c public udp-port port_number

where,

  • ip_address—IP address of the server

  • port_number—UDP port number assigned to receive the SNMP traps. The same port number must also be configured on the SNMP server.

Getting RPD Events

To retrieve events from RPD, use the cable rpd [RPD IP|RPD MAC|all] event {locallog|pending} command, as given in the following example:
Router#cable rpd 30.84.2.111 event pending

Clearing All Events on Cisco cBR Database

To remove all Events on Cisco cBR, use the clear cable rpd all event command, as given in the following example:
Router#clear cable rpd all event

Viewing the RPD Events

To view all RPD Events, use the show cable rpd [RPD IP|RPD MAC] event command as given in the following example. 
Router# show cable rpd 93.3.50.7 event 
RPD            EventId    Level Count  LastTime       Message
0004.9f00.0861 66070204   Error  1     Feb21 12:11:06 GCP Connection Failure 
CCAP-IP=30.85.33.2;RPD-ID=0004.9f00.0861;
0004.9f00.0861 2148074241 Error  1     Feb21 12:11:25 Session failed:connecting timeout, 
@SLAVE: 93.3.50.7:None --> 30.85.33.2:8190;RPD-ID=0004.9f00.0861;

Viewing RPD Events Using Log

To view all RPD Events, use the show logging command, as given in the following example. 
Router# show logging | include RPD-ID=0004.9f00.0861
004181: Feb 21 12:18:59.649 CST: %RPHYMAN-3-RPD_EVENT_ERROR:  CLC5: rphyman:
