watchdog threshold memory

To configure the value of memory available for each alarm threshold, use the watchdog threshold memory command in global configuration or interface configuration mode. To revert to the default threshold memory, use the no form of this command.

watchdog memory threshold [location node-id] minor percentage-memory-available severe percentage-memory-available critical percentage-memory-available

no watchdog memory threshold [location node-id] minor percentage-memory-available severe percentage-memory-available critical percentage-memory-available

Syntax Description

location node-id	Configures the threshold memory for a specified node. The node-id argument is entered in the rack/slot/module notation.
minor	Specifies the threshold for the minor state.
percentage-memory- available	Memory consumption percentage. Range is from 5 to 40.
severe	Specifies the threshold for the severe state.
critical	Specifies the threshold for the critical state.

Defaults

Use the show watchdog threshold memory defaults location all command to display the default memory thresholds.

Usage Guidelines

To use this command, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.

Use the watchdog threshold memory command to configure the memory thresholds. Threshold values can be applied to all nodes or a specific node using the location node-id keyword and argument. If the local threshold settings are removed, the local settings return to those set globally. In addition, you can view default and configured thresholds.

Table 6 lists the recommended memory threshold value calculations if the minor threshold is set to 20 percent, the severe threshold is set to 10 percent, and the critical threshold is set to 5 percent.

Table 6 Recommended Memory Threshold Values 

Total Available Memory (MB)	Minor Threshold (20 percent of available memory)	Severe Threshold (10 percent of available memory)	Critical Threshold (5 percent of available memory)
