Identifies which card in a chassis should assume revertive (redundancy auto-recovery) functionality should the slot/port being configured go down. This command must be issued on a per port basis, allowing you to configure specific ports to be used on individual LCs or SPIO cards. For example, ports 1 through 4 could be configured as "preferred" on the LC in slot 17 while ports 5 through 8 are "preferred" on the LC in slot 33. In this scenario, both LCs would be in an Active operational state while still providing LC and port redundancy for the other.

Identifies the physical slot in the chassis where the line card is installed.

no

Disables revertive, or auto-recovery, operation for the port.

Usage Guidelines

This command enables or disables revertive port redundancy. So after a port failover, when the original port is restored to service (i.e. link up) the system will return service to that port automatically.

Disabled, which is the default setting, causes non-revertive operation; requiring an administrative user to manually issue a port switch to command to return service to the original port.

Syntax Description

high_thresh

Default: 50

Sets the threshold for the highest percentage of port activity that must be met or exceeded, within the polling interval, to generate an alert or alarm.

high_thresh_% can be configured to any integer value between 0 and 100.

clear low_thresh

Default: 50

Sets the threshold for the lowest percentage level of port activity that must be met to generate and send a clear alarm. If port activity does not drop to or below this threshold then the alarm is maintained.

low_thresh_% can be configured to any integer value between 0 and 100.

Usage Guidelines

High port activity thresholds generate alerts or alarms based on the utilization percentage of each configured port during the specified polling interval. This threshold is configured on a per-port basis.

If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the polling interval.

Syntax

Syntax Description

[ no ] threshold monitoring

no

Disables threshold monitoring for port-level values. This is the default setting.

Usage Guidelines

Thresholding on the system is used to monitor the system for conditions that could potentially cause errors or outage. Typically, these conditions are temporary (i.e high-activity) and are quickly resolved. However, continuous or large numbers of these error conditions within a specific time interval may be indicative of larger, more severe issues. The purpose of thresholding is to help identify potentially severe conditions so that immediate action can be taken to minimize and/or avoid system downtime.

"Outstanding" alarms are reported to through the system's alarm subsystem and are viewable through the system's CLI.

The following table indicates the reporting mechanisms supported by each of the above models.

This command enables thresholding for port-level values. Refer to the threshold high-activity,threshold rx-utilization, and threshold tx-utilization commands in this chapter for information on configuring these values. In addition refer to the threshold poll command in the Global Configuration Mode Commands chapter of this reference for information on configuring the polling interval over which these values are monitored.

The low threshold receive port utilization percentage that maintains a previously generated alarm condition. If the utilization percentage falls below the low threshold within the polling interval, a clear alarm will be generated.

The percentage can be configured to any integer value between 0 and 100.

Usage Guidelines

Receive port utilization thresholds generate alerts or alarms based on the utilization percentage of each configured port in relation to data received during the specified polling interval. This threshold is configured on a per-port basis.

If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the polling interval.

Usage Guidelines

This command can be used to configure the line threshold whether the port is active or standby and sets a standard option for the paired values of the line's signal degrade and signal failure (SDSF) BER.

The SD is kept at a value of 100 erroredBits/sec less than the corresponding value of the SF. So if the SD threshold is configured at 1 error in every 100000 bits/sec, then the SF threshold automatically becomes 1 error in every 1000 bits/sec.

The port will go operationally down as soon as the SD threshold is crossed.

This command has been deprecated. Go to the frame-mapping keyword in the path command to configure this functionality.
