mpls total-crlsp-number threshold-alarm

Function

The mpls total-crlsp-number threshold-alarm command configures the alarm threshold for total constraint-based routed label switched path (CR-LSP) usage.

The undo mpls total-crlsp-number threshold-alarm command restores the default settings.

The default upper limit of the alarm threshold for total CR-LSP usage is 80%. The default lower limit of the clear alarm threshold for total CR-LSP usage is 75%.

Format

mpls total-crlsp-number threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

mpls total-crlsp-number { ingress | transit | egress } threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

undo mpls total-crlsp-number threshold-alarm

undo mpls total-crlsp-number { ingress | transit | egress } threshold-alarm

Parameters

Parameter	Description	Value
upper-limit upper-limit-value	Specifies the upper limit of the alarm threshold for total CR-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 80 is recommended.
lower-limit lower-limit-value	Specifies the lower limit of the clear alarm threshold for total CR-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 75 is recommended.
ingress	Specifies the alarm threshold for total ingress CR-LSPs.	-
transit	Specifies the alarm threshold for total transit CR-LSPs.	-
egress	Specifies the alarm threshold for total egress CR-LSPs.	-

Usage Guidelines

Usage Scenario

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

When the total CR-LSP usage increases to the value of upper-limit-value, an alarm for total CR-LSPs is generated.
When the total CR-LSP usage falls below the value of lower-limit-value, a clear alarm for total CR-LSPs is generated.

If you want to set the alarm threshold for total ingress CR-LSPs, total transit CR-LSPs or total egress CR-LSPs, run mpls total-crlsp-number { ingress | transit | egress } threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value.

Precautions

If the mpls total-crlsp-number threshold-alarm command is run more than once, the latest configuration overrides the previous one.
This command configures the alarm threshold for total CR-LSP usage. The alarm that the number of LSPs exceeded the upper threshold is generated only when the command snmp-agent trap enable feature-name mpls_lspm trap-name hwmplslspthresholdexceed is configured, and the actual total CR-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 command snmp-agent trap enable feature-name mpls_lspm trap-name hwmplslspthresholdexceedclear is configured, and the actual total CR-LSP usage falls below the lower limit of the clear alarm threshold.
