IP SLAs LSP Ping and LSP Traceroute Operations
This feature introduces support for the IP SLAs LSP ping and IP SLAs LSP traceroute operations. These
operations are useful for troubleshooting network connectivity issues and determining network
availability in an MPLS VPN. When using the LSP Health Monitor, IP SLAs LSP ping and LSP
traceroute operations are automatically created to measure network connectivity between the source PE
router and the discovered destination PE routers. Individual IP SLAs LSP ping and LSP traceroute
operations can also be manually configured. Manual configuration of these operations can be useful for
troubleshooting a connectivity issue.

by the MPLS LSP Ping and MPLS LSP Traceroute features, respectively, for sending and receiving echo
reply and request packets to test LSPs. For more information about the MPLS LSP Ping and MPLS LSP

Proactive Threshold Monitoring for the LSP Health Monitor
Proactive threshold monitoring support for the LSP Health Monitor feature provides the capability for
triggering SNMP trap notifications and syslog messages when user-defined reaction conditions (such as
a connection loss or timeout) are met. Configuring threshold monitoring for an LSP Health Monitor
