Checking Connectivity of a VLL Network

Checking Connectivity of a VLL Network

Prerequisites

After a VLL network is established, perform a virtual circuit connectivity verification (VCCV) to check the 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 a tool for manually locating an abnormal node on a PW.

VCCV supports the following modes: control word channel mode, normal mode in the Martini VLL, and Label Alert mode. By default, VCCV in Label Alert mode is enabled. Before using the control word channel mode, 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 a VLL network.

    Check 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 ] [ pipe | 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 ] [ pipe | 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 ] * [ pipe | 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 ] [ pipe | uniform ]

    Check the connectivity of the VLL network in Kompella mode.
    • Control word channel

      ping vc vpn-instance vpn-name local-ce-id remote-ce-id [ -c echo-number | -m time-value | -s data-bytes | -t timeout-value | -exp exp-value | -r reply-mode | -v ] * control-word

    • Label Alert channel

      ping vc vpn-instance vpn-name local-ce-id remote-ce-id [ -c echo-number | -m time-value | -s data-bytes | -t timeout-value | -exp exp-value | -r reply-mode | -v ] * label-alert

  • Locate the fault on a VLL network.

    Locate 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 ] [ pipe | 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 ] [ pipe | 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-pw-id draft6 [ full-lsp-path ] [ pipe | 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 ] [ pipe | 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 ] [ pipe | uniform ]

    Locate the fault on the VLL network in Kompella mode.
    • Control word channel

      tracert vc -vpn-instance vpn-name local-ce-id remote-ce-id [ -exp exp-value | -f first-ttl | -m max-ttl | -r reply-mode | -t timeout-value ] * { control-word | draft6 } [ full-lsp-path ]

    • Label Alert channel

      tracert vc -vpn-instance vpn-name local-ce-id remote-ce-id [ -exp exp-value | -f first-ttl | -m max-ttl | -r reply-mode | -t timeout-value ] * label-alert [ full-lsp-path ]
