CLI commands overview

The MPLS Topology Server component of MPLS Manager uses CLI commands to perform CLI discovery for any of the following conditions:

• SNMP discovery fails.

• MIB is not supported by the target device.

• MIB cannot provide the required information.

  For these conditions, the MPLS Topology Server establishes a Telnet, SSH1, or SSH2 connection to the target device and issues specific CLI “show” commands to discover MPLS and VPN topology objects and their relationships.

  The MPLS Topology Server also uses CLI commands to execute on-demand LSP ping requests. For LSP ping execution, the MPLS Topology Server establishes a Telnet, SSH1, or SSH2 connection to the target device and issues a specific CLI “ping” command to start the LSP ping, and parses the ping command output to obtain the LSP ping test results.
