time-period	Time period, in hours, that PXF crashes are monitored. The valid range is 0 to 120 hours, with a default of 5.

Command Default

2 PXF crashes within 5 hours are allowed (switchover pxf restart 2 5)

Command Modes

Redundancy configuration, main-cpu mode

Command History

Release	Modification
12.2(15)BC2	This command was introduced for the Cisco uBR10012 router.
IOS-XE 3.15.0S	This command is not supported on the Cisco cBR Series Converged Broadband Routers.

Usage Guidelines

The PXF processors that are onboard the PRE1 module automatically restart themselves if a crash occurs. Occasional crashes could be expected, but repeated crashes could indicate a hardware problem.

The switchover pxf restart command specifies the maximum number of times that a PXF processor can crash during a specified time period before the router switches over to the redundant PRE1 module. If the PXF processors crash this number of times, the router assumes a hardware problem and initiates a switchover to the redundant PRE1 module.

Note

When a switchover occurs because of repeated PXF crashes, the router displays the following system message: C10KEVENTMGR-3-PXF_FAIL_SWITCHOVER: Multiple PXF failures, switchover to redundant PRE initiated.

Examples

The following example shows how to configure the router so that if five PXF crashes occur within a one-hour period, the router should initiate a switchover to the redundant PRE1 module.

Router# config t
 
Router(config)# redundancy
 
Router(config-r)# main-cpu
 
Router(config-r-mc)# switchover pxf restart 5 1 
Router(config-r-mc)# exit
 
Router(config-f)# exit
 
Router(config)#

switchover timeout

To configure the switchover timeout period of the PRE1 module, use the switchover timeout command in redundancy configuration (main-cpu) mode. To reset the timeout period to its default value, use the no form of this command.

switchover timeout timeout-period

no switchover timeout

Syntax Description

timeout-period

Specifies the timeout, in milliseconds. The range is 0 to 25000 milliseconds (25 seconds), where 0 specifies no timeout period.

Command Default

0

Command Modes

Redundancy configuration, main-cpu mode

Command History

Release	Modification
12.2(11)BC3	This command was introduced for the Cisco uBR10012 router.
IOS-XE 3.15.0S	This command is not supported on the Cisco cBR Series Converged Broadband Routers.

Usage Guidelines

The switchover timeout command specifies how long the standby PRE module should wait when it does not detect a heartbeat from the active PRE module before initiating a switchover and assuming responsibility as the active PRE module. If set to 0, the standby PRE module initiates a switchover immediately when the active PRE module misses a scheduled heartbeat.

Examples

The following example shows how to set the timeout period to 60 milliseconds:

Router# config t
 
Router(config)# redundancy
 
Router(config-r)# main-cpu
 
Router(config-r-mc)# switchover timeout 60
 
Router(config-r-mc)# exit

Command History

Release	Modification
12.2(15)BC2	This command was introduced for the Cisco uBR7246VXR and Cisco uBR10012 universal broadband routers.
IOS-XE 3.15.0S	This command is not supported on the Cisco cBR Series Converged Broadband Routers.

Usage Guidelines

In Cisco IOS Release 12.2(15)BC2 and later, the Cisco CMTS router supports three different modes of operation, depending on the cable interface line cards being used. The range of frequencies that are allowed in each mode are as follows:

North American DOCSIS (Annex B)—Upstreams use frequencies between 5 MHz and 42 MHz.
European EuroDOCSIS (Annex A)—Upstreams use frequencies between 5 MHz and 65 MHz.
Japanese Expanded Range (Annex B)—Upstreams use frequencies between 5 MHz and 55 MHz.

To configure the router so that it supports the proper range of upstream frequencies, use the upstream freq-range command. After you have configured the router with the upstream freq-range command, the cable upstream frequency command then accepts only frequencies that are in the configured range.

Note

This command configures only the range of frequencies that can be configured on an upstream. It does not configure the upstreams for the DOCSIS (Annex B) or EuroDOCSIS (Annex A) modes of operation, which is done using the cable downstream annex interface command. (Annex C mode is not supported.)

The allowable range for the upstream channel frequency depends on the cable interface line card and Cisco IOS software release being used. See Table 2-12 for the currently supported values.

Examples

The following example shows how to configure the Cisco CMTS router to support the EuroDOCSIS upstream frequency range of 5 MHz to 65 MHz:

Router# configure terminal
 
Router(config)# upstream freq-range european
 
Router(config)#

The following example shows how to configure the Cisco CMTS router to support the expanded Japanese upstream frequency range of 5 MHz to 55 MHz:

Command Modes

Controller configuration (config-controller)

Command History

Release	Modification
IOS-XE 3.15.OS	This command was introduced on the Cisco cBR Series Converged Broadband Routers. This command replaces the cable upstream channel-width command.

Usage Guidelines

When you specify both channel width values, the smaller value is taken as the last-choice-width parameter and the larger value is taken as the first-choice-width parameter. In the event of noise in the channel, the symbol rate automatically steps down to a value that is lower than the first-choice-width and greater or equal to the last-choice-width to maintain a stable channel.

Refer to the cable upstream channel-width command for more information.

Examples

The following example shows how to set the channel-width using us-channel channel-width command:

Router# configure terminal
Router(config)# controller Upstream-Cable 3/0/0
Router(config-controller)# us-channel 1 channel-width 1600000

0 dBmV

Command Modes

Controller configuration—upstream-cable only (config-controller)

Command History

Release	Modification
IOS-XE 3.15.0S	This command was implemented on the Cisco cBR Series Converged Broadband Routers. This command replaces the cable upstream power-level command.

Usage Guidelines

The Cisco CMTS controls the output power levels of the CMs to meet the desired upstream input power level. The nominal input power level for the upstream RF carrier is specified in decibels per millivolt (dBmV). The default setting of 0 dBmV is the optimal setting for the upstream power level.

The valid range for the input power level depends on the data rate, as expressed as the symbol rate and channel width. The table below shows the valid power levels for each allowable rate, as given in the DOCSIS specification. Higher (more positive) values cause the CMs to increase their transmit power, achieving a greater carrier-to-noise ratio (CNR).

Table 2 Allowable DOCSIS Power Levels
Symbol Rate (Symbols per second)	Channel Width (Hz)	Allowable Power Range (dBmV)
160,000	200,000	–16 to +14 (minimum valid value for DOCSIS is –13)
320,000	400,000	–13 to +17
640,000	800,000	–10 to +20
1,280,000	1,600,000	–7 to +23
2,560,000	3,200,000	–4 to +26 (maximum valid value for DOCSIS is +23)
5,120,000¹	6,400,000	–1 to +29 (maximum valid value for DOCSIS is +23)

¹ The 5.12 MSymbols/sec symbol rate and 6.4 MHz channel width are supported only on upstreams that are configured for DOCSIS 2.0 A-TDMA-only operation.

Tip

You can use inline attenuators to force CMs to transmit at higher power levels and to achieve a higher CNR value on the network.

Caution

If you increase the input power level or add inline attenuators before the Cisco CMTS, the CMs on your HFC network increase their transmit power level. Be careful if you adjust this parameter. You might violate the upstream return laser design parameters or exceed the CM’s maximum transmit power level.

Note

Do not adjust your input power level by more than 5 dB in a 30-second interval. If you increase the power level by more than 5 dB within 30 seconds, you will disrupt CM service on your network. If you decrease the power level by more than 5 dB within 30 seconds, the CMs on your network will be forced to re-range.

Tip

When setting upstream power levels, we recommend that the adjacent channels of equal bandwidth do not have a large variation. The recommended maximum input power variance is 5 to 6 dB.

Examples

The following example shows how to input power level for upstream channel 10 on the Cisco cBR-8 router:

Router# configure terminal
Router(config)# controller upstream-Cable 3/0/1
Router(config-controller)# us-channel 10 power-level 22
Router(config-controller)#

Syntax Description

minutes	Specifies the size of the sliding window (in minutes) during which subscriber usage is monitored. The range is 10 to 44640 with a default of 360 minutes (6 hours).
avg-rate rate	Specifies the average sampling rate in kilobits per second for the specified duration. The range is 1 to 400000 kilobits with no default.
sample-interval interval	Specifies how often (in minutes) the CMTS router should sample a service flow to get an estimate of subscriber usage. The range is 1 to 30, with a default value of 15.
(Optional) Specifies the period (in minutes) during which a cable modem (CM) can be under penalty. The range is 1 to 10080. penalty-period minutes	(Optional) Specifies the period (in minutes) during which a cable modem (CM) can be under penalty. The range is 1 to 10080. (Optional) Specifies the period during which an enforced quality of service (QoS) profile should be in force for subscribers who violate their registered QoS profile. The range is 1 to 10080.
downstream	Specifies monitoring of traffic in the downstream direction.
upstream	Specifies monitoring of traffic in the upstream direction.
enforce	(Optional) Specifies that the enforce-rule QoS profile should be applied automatically if a user violates their registered QoS profile.

12.2(33)SCD2	The penalty keyword option was added.
IOS-XE 3.15.0S	This command is not supported on the Cisco cBR Series Converged Broadband Routers.
IOS-XE 3.17.0S	This command was implemented on the Cisco cBR Series Converged Broadband Routers.

Usage Guidelines

Note

This command is applicable only after the monitoring-basics command is configured with the keyword legacy.

The weekend duration command works similarly to the duration command for subscriber traffic monitoring. Use the weekend duration command when you want to configure different monitoring parameters for subscribers on weekends.

This command can only be used when you have already configured the duration or peak-time1 commands as weekday monitoring conditions for an enforce-rule.

If you still want to monitor traffic over the weekend, but want to return to the same monitoring conditions for every day of the week, use the no weekend command. This command removes the weekend monitoring conditions, but still performs monitoring over the weekends according to the other monitoring options that you have configured in the enforce-rule.

If you want to disable monitoring entirely over the weekend, use the weekend off command.

The penalty duration, which is configured using the weekend duration command, is unique to weekends, and takes precedence over the global penalty duration configured using the penalty-period command.

Examples

The following example specifies automatic monitoring of upstream traffic over the weekend if a subscriber is identified as violating their QoS profile. The monitoring will take place every 10 minutes and last for 5 minutes, with traffic sampled at an average rate of 2 kb/s:

Router(enforce-rule)# weekend duration 5 avg-rate 2 sample-interval 10 penalty 11 upstream enforce

Related Commands

Command	Description
duration	Specifies the time period and sample rate to be used for monitoring subscribers.

no weekend off

Syntax Description

This command has no arguments or keywords.

Command Default

Weekend monitoring is enabled once you configure the weekend duration or weekend peak-time1 commands.

Command Modes

Enforce-rule configuration (enforce-rule)

Command History

Release	Modification
12.3(23)BC2	This command was introduced.
12.2(33)SCB	This command was integrated into Cisco IOS Release 12.2(33)SCB. Support for the Cisco uBR7225VXR router was added.
IOS-XE 3.15.0S	This command is not supported on the Cisco cBR Series Converged Broadband Routers.
IOS-XE 3.17.0S	This command was implemented on the Cisco cBR Series Converged Broadband Routers.

Usage Guidelines

Use the weekend off command to disable previously configured weekend monitoring and stop the CMTS router from monitoring cable modems (CMs) with that enforce-rule over the weekend. This command allows you to retain or modify your weekend monitoring configuration without enabling it for actual monitoring use on the CMTS router.

To perform weekend monitoring according to the same parameters used for weekday monitoring, use the no weekend command.

Examples

The following example shows how to disable weekend monitoring when weekend peak-time monitoring has previously been configured on a Cisco CMTS router:

Router(config)# cable qos enforce-rule test
Router(enforce-rule)# weekend peak-time1 8 duration 60 avg-rate 100 peak-time2 20 duration 60 avg-rate 10000 duration 90 avg-rate 20000 sample-interval 20 downstream enforce
