Maintaining VXLAN

Maintaining VXLAN

This section describes how to clear VXLAN statistics and monitor the VXLAN running status.

Configuring the VXLAN Alarm Function

To learn about the VXLAN operating status in time, configure the VXLAN alarm function so that the NMS will be notified of the VXLAN status changes. This facilitates O&M.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run snmp-agent trap enable feature-name nvo3 [ trap-name { hwnvo3vxlantnldown | hwnvo3vxlantnlup } ]

    The VXLAN alarm function is enabled.

  3. Run commit

    The configuration is committed.

Verifying the Configuration

After the VXLAN alarm function is enabled, check the VXLAN alarm status.

Run the display snmp-agent trap feature-name nvo3 all command to check configurations of all alarm functions of the VXLAN module.

<HUAWEI> display snmp-agent trap feature-name nvo3 all
------------------------------------------------------------------------------
Feature name: NVO3
Trap number : 2
------------------------------------------------------------------------------
Trap name                      Default switch status   Current switch status
hwNvo3VxlanTnlDown             off                     on
hwNvo3VxlanTnlUp               off                     on

Collecting and Checking VXLAN Packet Statistics

To check the network status or locate network faults, you can enable the traffic statistics function to view VXLAN packet statistics.

Procedure

  • Collect and view VXLAN packet statistics in a BD.
    1. Run system-view

      The system view is displayed.

    2. Run bridge-domain bd-id

      A BD is created, and the BD view is displayed.

    3. Run statistic enable

      VXLAN packet statistics in a BD is enabled.

    4. Run commit

      The configuration is committed.

  • Collect and view VXLAN packet statistics collected by VNI.
    1. Run system-view

      The system view is displayed.

    2. Run vni vni-id

      A VNI is created, and the VNI view is displayed.

    3. Run statistic enable

      VXLAN packet statistics collection is enabled.

    4. Run commit

      The configuration is committed.

  • Collect and view VXLAN packet statistics collected by VNI and VXLAN tunnel.
    1. Run system-view

      The system view is displayed.

    2. Run interface nve nve-number

      An NVE interface is created, and the NVE interface view is displayed.

    3. Run source ip-address

      The IP address of the source VTEP is configured.

    4. Run vni vni-id head-end peer-list ip-address &<1-10>

      An ingress replication list is configured for the VNI.

    5. Run vxlan statistics peer peer-ip vni vni-id [ inbound | outbound ] enable

      VXLAN packet statistics collection by VNI and VXLAN tunnel is displayed.

    6. Run vxlan statistic l3-mode peer peer-ip vni vni-id inbound enable

      Upstream Layer 3 traffic statistics collection by VNI and VXLAN tunnel is enabled.

      Run vxlan statistics l3-mode peer peer-ip [ vni vni-id ] outbound enable

      Downstream Layer 3 traffic statistics collection by VNI and VXLAN tunnel is enabled.

    7. Run commit

      The configuration is committed.

Postrequisite

  • Run the display bridge-domain vni vni-id command to view VXLAN packet statistics in the BD.
  • Run the display vxlan statistics vni vni-id command to view VXLAN packet statistics collected by VNI.
  • Run the display vxlan statistics source source-ip peer peer-ip vni vni-id command to view VXLAN packet statistics collected by VNI and VXLAN tunnel.
  • Run the display vxlan statistics l3-mode source source-ip peer peer-ip local-vni vni-id command to view upstream Layer 3 VXLAN traffic statistics collected by VNI and VXLAN tunnel.
  • Run the display vxlan statistics l3-mode source source-ip peer peer-ip remote-vni vni-id command to view downstream Layer 3 VXLAN traffic statistics collected by VNI and VXLAN tunnel.

Clearing VXLAN Packet Statistics

This section describes how to clear VXLAN packet statistics in a BD, VXLAN packet statistics collected per VNI, or per VNI and VXLAN tunnel.

Context

NOTE:

Packet statistics cannot be restored after they are cleared. Exercise caution when running the reset commands.

Procedure

  • Run the reset bridge-domain bd-id statistics command in the user view to delete packet statistics in a specified BD.
  • Run the reset vxlan statistics vni vni-id command in the user view to delete VXLAN packet statistics collected per VNI.
  • Run the reset vxlan statistics source source-ip peer peer-ip vni vni-id command in the user view to delete packet statistics collected per VNI and VXLAN tunnel.
  • Run the reset vxlan statistics source source-ip peer peer-ip local-vni local-vni-id command in the user view to delete upstream VXLAN packet statistics collected based on the local VNI ID.
  • Run the reset vxlan statistics source source-ip peer peer-ip remote-vni remote-vni-id command in the user view to delete downstream VXLAN packet statistics collected based on the remote VNI ID.
  • Run the reset vxlan statistics l3-mode source source-ip peer peer-ip local-vni vni-id command in the user view to delete Layer 3 upstream packet statistics collected per VNI and VXLAN tunnel.
  • Run the reset vxlan statistics l3-mode source source-ip peer peer-ip remote-vni vni-id command in the user view to delete Layer 3 downstream packet statistics collected per VNI and VXLAN tunnel.

Checking Statistics about MAC Address Entries in a BD

Statistics about MAC address entries in a BD can be viewed to monitor the VXLAN operating status.

Context

In routine maintenance, run the following commands in any view to check the VXLAN operating status.

Procedure

  • Run the display mac-address [ mac-address ] bridge-domain bd-id command to check statistics about all MAC address entries in a BD.

Clearing Statistics about Dynamic MAC Address Entries in a BD

To view dynamic MAC address entries in a BD within a specified period of time, clear existing dynamic MAC address entry information before starting statistics collection to ensure information accuracy.

Context

NOTE:

Statistics about dynamic MAC address entries in a BD cannot be restored after they are cleared. Exercise caution when running the reset command.

Procedure

  • Run the reset mac-address bridge-domain bd-id command in the user view to clear statistics about dynamic MAC address entries in a BD.
