mpls rsvp-lsp-number threshold-alarm

Function

The mpls rsvp-lsp-number threshold-alarm command configures the alarm threshold for Resource Reservation Protocol (RSVP) label switched path (LSP) usage.

The undo mpls rsvp-lsp-number threshold-alarm command restores the default setting.

By default, the upper limit of the alarm threshold for RSVP LSP usage is 80%. The default lower limit of the clear alarm threshold for RSVP LSP usage is 75%.

Format

mpls rsvp-lsp-number threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

undo mpls rsvp-lsp-number threshold-alarm

Parameters

Parameter	Description	Value
lower-limit lower-limit-value	Specifies the lower limit of the clear alarm threshold for RSVP LSP usage.	The value is an integer ranging from 1 to 100, represented in percentage. The value must be smaller than the value of upper-limit-value. Using the default value is recommended.
upper-limit upper-limit-value	Specifies the upper limit of the alarm threshold for RSVP LSP usage.	The value is an integer ranging from 1 to 100, represented in percentage. Using a value larger than 95 is not recommended. Using the default value is recommended.

Parameter

Description

Value

lower-limit lower-limit-value

Specifies the lower limit of the clear alarm threshold for RSVP LSP usage.

The value is an integer ranging from 1 to 100, represented in percentage. The value must be smaller than the value of upper-limit-value. Using the default value is recommended.

upper-limit upper-limit-value

Specifies the upper limit of the alarm threshold for RSVP LSP usage.

The value is an integer ranging from 1 to 100, represented in percentage. Using a value larger than 95 is not recommended. Using the default value is recommended.

Usage Guidelines

Usage Scenario

If the number of RSVP LSPs in the system reaches a specific limit, establishing subsequent RSVP LSPs may fail because of insufficient resources. To facilitate user operation and maintenance, enable an alarm to be generated when the number of RSVP LSPs reaches the specific limit. To configure the alarm threshold for RSVP LSP usage, run the mpls rsvp-lsp-number threshold-alarm command. The parameters in this command are described as follows:

When the RSVP LSP usage increases to the value of upper-limit-value, an alarm for RSVP LSPs is generated. The alarm name is MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.63 hwMplsLspThresholdExceed.
When the RSVP LSP usage falls below the value of lower-limit-value, a clear alarm for RSVP LSPs is generated. The alarm name is MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.64 hwMplsLspThresholdExceedClear.
When RSVP LSP usage reaches a specified threshold, an RSVP LSP threshold-crossing alarm is generated. The alarm name is MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.65 hwMplsLspTotalCountExceed.
When RSVP LSP usage falls below 95% of a specified threshold, an RSVP LSP threshold-crossing alarm is cleared. The alarm name is MPLS_LSPM_1.3.6.1.4.1.2011.5.25.121.2.1.66 hwMplsLspTotalCountExceedClear.

Precautions

If the mpls rsvp-lsp-number threshold-alarm command is run more than once, the latest configuration overrides the previous one.

This command configures the alarm threshold for RSVP LSP usage. The alarm that the number of LSPs reached the upper threshold is generated only when the snmp-agent trap enable feature-name command is run, and the actual RSVP LSP usage reaches the upper limit of the alarm threshold. The alarm that the number of LSPs fell below the lower threshold is generated only when the snmp-agent trap enable feature-name feature-name command is run, and the actual RSVP LSP usage falls below the lower limit of the clear alarm threshold.

Example
