[DCN] How to check VXLAN Connectivity Using Ping/Tracert Operation

• Check IPv4 VXLAN tunnel connectivity.
  1. Run system-view

     The system view is displayed.

  2. (Optional) Run nqa vxlanecho enable udp-port port-number [ source-ip-interface interface-type interface-number ]

     The VXLAN ping function is enabled for the initiator.

     NOTE:

     This step is mandatory if the ping vxlan command is to be run on the initiator with the -r replymode parameter set to 3. Otherwise, skip this step.

  3. Run nqa vxlanecho enable udp-port port-number [ source-ip-interface interface-type interface-number ]

     The VXLAN ping function is enabled for the responder, and the number of the listening port on the VXLAN server is configured for the NQA test.

  4. Run ping vxlan [ -c count | -m interval | -t timeout | -r replymode | -tos tos | -a innersrc-address ] ^*vni vniid source source-address peer dest-address [ udp-port dest-port ] [ load-balance { vxlan-source-udpport vxlan-source-udpport [ endvxlansrcudport ] | { source-address lb-src-address destination-address lb-dst-address protocol { udp | lb-protocolid } source-port lb-src-port destination-port lb-dst-port source-mac source-mac destination-mac destination-mac } } ]

     IPv4 VXLAN tunnel connectivity is checked.

• Check IPv6 VXLAN tunnel connectivity.

1. Run system-view

   The system view is displayed.

2. (Optional) Run nqa vxlanecho enable ipv6 udp-port port-number [ source-ip-interface interface-type interface-number ]

   The VXLAN ping function is enabled for the initiator.

   NOTE:

   This step is mandatory if the ping vxlan command is to be run on the initiator with the -r replymode parameter set to 3. Otherwise, skip this step.

3. Run nqa vxlanecho enable ipv6 udp-port port-number [ source-ip-interface interface-type interface-number ]

   The VXLAN ping function is enabled for the responder, and the number of the listening port on the VXLAN server is configured for the NQA test.

4. Run ping vxlan [ -c count | -m interval | -t timeout | -r replymode | -a innersrc-address6 ] ^*ipv6 vni vniid source source-address6 peer dest-address6 [ udp-port dest-port ] [ load-balance { vxlan-source-udpport vxlan-source-udpport [ endvxlansrcudport ] | { source-address lb-src-address destination-address lb-dst-address protocol { udp | lb-protocolid } source-port lb-src-port destination-port lb-dst-port source-mac source-mac destination-mac destination-mac } } ]

   IPv6 VXLAN tunnel connectivity is checked.

Tracert Operation:

1. Run system-view

   The system view is displayed.

2. (Optional) Run nqa vxlanecho enable udp-port port-number [ source-ip-interface interface-type interface-number ]

   The VXLAN tracert function is enabled for the initiator.

   NOTE:

   This step is mandatory if the tracert vxlan command is to be run on the initiator with the -r replymode parameter set to 3. Otherwise, skip this step.

3. Run nqa vxlanecho enable udp-port port-number [ source-ip-interface interface-type interface-number ]

   The VXLAN tracert function is enabled for the responder, and the number of the listening port on the VXLAN server is configured for the NQA test.

4. Locate an IPv4 VXLAN tunnel fault.

   Run tracert vxlan [ -h maxttl | -t timeout | -r replymode | -a innersrc-address ] ^*vni vniid source source-address peer dest-address [ udp-port dest-port ] [ pipe ] [ load-balance { vxlan-source-udpport vxlan-source-udpport | { source-address lb-src-address destination-address lb-dst-address protocol { udp | lb-protocolid } source-port lb-src-port destination-port lb-dst-port source-mac lb-sourcemac destination-mac lb-destinationmac } } ]

   The device is configured to locate the IPv4 VXLAN tunnel fault.
