Configuring a PWE3 Trace Test Instance on a Single-Hop PW

Configuring a PWE3 Trace Test Instance on a Single-Hop PW

Context

An NQA PWE3 trace test detects the forwarding path of an MPLS-based PW and collects statistics about each device along the forwarding path.

The PWE3 trace test provides functions similar to the tracert vc command but provides richer outputs.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run nqa test-instance admin-name test-name

    An NQA test instance is created and the test instance view is displayed.

  3. Run test-type pwe3trace

    The test type is set to PWE3 Trace.

  4. (Optional) Run vc-type ldp

    The method of setting up a PW is configured.

  5. (Optional) Run local-pw-type local-pw-type

    The type of the local PW is configured. By default, the type is Ethernet.

  6. Run lsp-version { rfc4379 | draft6 }

    A protocol is configured for the LSP test instance.

  7. (Optional) Run label-type { control-word | { label-alert | normal } [ no-control-word ] }

    The type of the PW label is configured.

    NOTE:

    If the PW label type is set to control-word, the control word feature must be enabled for the PW.

  8. Run local-pw-id local-pw-id

    The ID of the local end of the PW is configured.

  9. (Optional) Run the following commands to configure other parameters for the PWE3 trace test:

    • To configure the response mode of the Echo packet, run the lsp-replymode { no-reply | udp } command.

    • To configure the LSP EXP value, run the lsp-exp exp command.

    • To configure maximum hops of the PWE3 trace test, run the tracert-hopfailtimes times command.

    • To configure the initial TTL value and maximum TTL value of the packet, run the tracert-livetime first-ttl first-ttl max-ttl max-ttl command.
