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 settings.

The default 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

mpls rsvp-lsp-number { ingress | transit | egress } threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

undo mpls rsvp-lsp-number threshold-alarm

undo mpls rsvp-lsp-number { ingress | transit | egress } threshold-alarm

Parameters

Parameter	Description	Value
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 80 is recommended.
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 75 is recommended.
ingress	The alarm that the number of ingress RSVP LSPs reached the upper threshold is generated.	-
transit	The alarm that the number of transit RSVP LSPs reached the upper threshold is generated.	-
egress	The alarm that the number of egress RSVP LSPs reached the upper threshold is generated.	-

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.
When the RSVP LSP usage falls below the value of lower-limit-value, a clear alarm for RSVP LSPs is generated.

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

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 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 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 command snmp-agent trap enable feature-name mpls_lspm trap-name hwmplslspthresholdexceedclear is configured, and the actual RSVP LSP usage falls below the lower limit of the clear alarm threshold.
