Configuring IP SLA MPLS LSP Ping and Trace Operations
The MPLS LSP ping and trace operations allow service providers to monitor label switched paths (LSPs) and
quickly isolate MPLS forwarding problems. Use these IP SLA operations to troubleshoot network connectivity
between a source router and a target router. To test LSPs, the MPLS LSP ping and trace operations send echo
request packets and receive echo reply packets.
To configure and schedule an MPLS LSP ping or trace operation, perform one of the following tasks:

Configuring and Scheduling an MPLS LSP Ping Operation

An MPLS LSP ping operation tests connectivity between routers along an LSP path in an MPLS network by
sending an echo request (User Datagram Protocol (UDP) packet) to the end of the LSP, and receiving an echo
reply back that contains diagnostic data.

Purpose
(Optional) Specifies that the operation starts
automatically at the specified time and for the specified
duration every day.
Specifies a time for the operation to start. The following
keywords are described:
• (Optional) Use the pending keyword to configure
the operation to remain in a pending (unstarted)
state. The default value is inactive. If the
start-time command is not specified, no
information is collected until the start time is
configured or a trigger occurs that performs an
immediate start.
• (Optional) Use the now keyword to indicate that
the operation should start immediately.
• (Optional) Use the after keyword and associated
arguments to specify the time after which the
operation starts collecting information.
Displays the current statistics.
