Checking Connectivity of the VLL Network

Checking Connectivity of the VLL Network

Prerequisites

After a VLL network is established, perform a virtual circuit connectivity verification (VCCV) to check connectivity of the VLL network.

VCCV is an end-to-end fault detection and diagnosis mechanism which includes VCCV ping and VCCV tracert. VCCV ping is a tool for manually testing VC connectivity; while VCCV tracert is tool for manually locating an abnormal node on a PW.

VCCV supports the following modes: control word channel mode and Label Alert mode. By default, VCCV in Label Alert mode is enabled. Before using the control word channel mode, you need to run the control-word command to enable the control word function. After that, VCCV in control word channel mode can be used.

NOTE:

When locating the fault on the VLL network in Martini mode, you can use either VCCV in control word channel mode or VCCV in normal mode.

Procedure

  • Check the connectivity of the VLL network.

    Checking the connectivity of the VLL network in Martini mode.
    • Control word channel

      ping vc pw-type pw-id [ -c echo-number | -m time-value | -s data-bytes | -t timeout-value | -exp exp-value | -r reply-mode | -v ] * control-word [ remote remote-ip-address peer-pw-id | draft6 ] * [ ttl ttl-value ] [ uniform ]

      ping vc pw-type pw-id [ -c echo-number | -m time-value | -s data-bytes | -t timeout-value | -exp exp-value | -r reply-mode | -v ] * control-word remote remote-ip-address peer-pw-id sender sender-address [ ttl ttl-value ] [ uniform ]

    • Label Alert channel

      ping vc pw-type pw-id [ -c echo-number | -m time-value | -s data-bytes | -t timeout-value | -exp exp-value | -r reply-mode | -v ] * label-alert [ no-control-word ] [ remote remote-ip-address | draft6 ] * [ uniform ]

    • Normal mode

      ping vc pw-type pw-id [ -c echo-number | -m time-value | -s data-bytes | -t timeout-value | -exp exp-value | -r reply-mode | -v ] * normal [ no-control-word ] [ remote remote-ip-address peer-pw-id ] [ ttl ttl-value ] [ uniform ]

  • Locate the fault on the VLL network.

    Locating the fault on the VLL network in Martini mode.
    • Control word channel

      tracert vc pw-type pw-id [ -exp exp-value | -f first-ttl | -m max-ttl | -r reply-mode | -t timeout-value ] * control-word [ draft6 ] [ full-lsp-path ] [ uniform ]

      tracert vc pw-type pw-id [ -exp exp-value | -f first-ttl | -m max-ttl | -r reply-mode | -t timeout-value ] * control-word remote remote-ip-address [ ptn-mode | full-lsp-path ] [ uniform ]

    • Label Alert channel

      tracert vc pw-type pw-id [ -exp exp-value | -f first-ttl | -m max-ttl | -r reply-mode | -t timeout-value ] * label-alert [ no-control-word ] [ remote remote-ip-address ] [ full-lsp-path ] [ draft6 ] [ uniform ]

    • Normal mode

      tracert vc pw-type pw-id [ -exp exp-value | -f first-ttl | -m max-ttl | -r reply-mode | -t timeout-value ] * normal [ no-control-word ] [ remote remote-ip-address ] [ full-lsp-path ] [ draft6 ] [ uniform ]
