Example for Configuring MAC Ping to Detect the Connectivity of a VLAN network

Procedure

1. Add Switch A and Switch B to VLAN 10.

   # Configure Switch A.

   <HUAWEI> system-view

   [HUAWEI] sysname SwitchA

   [SwitchA] vlan 10

   [SwitchA-vlan10] quit

   [SwitchA] interface gigabitethernet 0/0/1

   [SwitchA-GigabitEthernet0/0/1] port link-type hybrid

   [SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 10

   [SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 10

   [SwitchA-GigabitEthernet0/0/1] quit

   # Configure Switch B.

   <HUAWEI> system-view
   [HUAWEI] sysname SwitchB
   [SwitchB] vlan 10
   [SwitchB-vlan10] quit
   [SwitchB] interface gigabitethernet 0/0/1
   [SwitchB-GigabitEthernet0/0/1] port link-type hybrid
   [SwitchB-GigabitEthernet0/0/1] port hybrid pvid vlan 10
   [SwitchB-GigabitEthernet0/0/1] port hybrid untagged vlan 10
   [SwitchB-GigabitEthernet0/0/1] quit

2. Enable basic Ethernet CFM functions between Switch A and Switch B, and establish the mapping relationship between the MA and VLAN 10.

   # Configure Switch A.

   [SwitchA] cfm enable

   [SwitchA] cfm md md1

   [SwitchA-md-md1] ma ma1

   [SwitchA-md-md1-ma-ma1] map vlan 10

   [SwitchA-md-md1-ma-ma1] mep mep-id 1 interface gigabitethernet 0/0/1 outward

   [SwitchA-md-md1-ma-ma1] mep ccm-send mep-id 1 enable

   [SwitchA-md-md1-ma-ma1] remote-mep mep-id 2

   [SwitchA-md-md1-ma-ma1] remote-mep ccm-receive mep-id 2 enable

   [SwitchA-md-md1-ma-ma1] quit

   [SwitchA-md-md1] quit

   # Configure Switch B.

   [SwitchB] cfm enable

   [SwitchB] cfm md md1

   [SwitchB-md-md1] ma ma1

   [SwitchB-md-md1-ma-ma1] map vlan 10

   [SwitchB-md-md1-ma-ma1] mep mep-id 2 interface gigabitethernet 0/0/1 outward

   [SwitchB-md-md1-ma-ma1] mep ccm-send mep-id 2 enable

   [SwitchB-md-md1-ma-ma1] remote-mep mep-id 1

   [SwitchB-md-md1-ma-ma1] remote-mep ccm-receive mep-id 1 enable

   [SwitchB-md-md1-ma-ma1] quit

   [SwitchB-md-md1] quit

   

   Each interface can be configured with only one MEP and the interface must be a Layer 2 interface.

   Run the display cfm remote-mep command on Switch A to view the status of Ethernet CFM. The command output shows that the status of Ethernet CFM is Up.

   [SwitchA] display cfm remote-mep

   The total number of RMEPs is : 1
   The status of RMEPS : 1 up, 0 down, 0 disable
   --------------------------------------------------
    MD Name            : md1
    Level              : 0
    MA Name            : ma1
    RMEP ID            : 2
    VLAN ID            : 10

    L2VC ID            : --
    MAC                : 00e0-fca4-8ae7
    CCM Receive        : enabled
    Trigger-If-Down    : disabled
    CFM Status         : up
    Alarm Status       : none
    Interface TLV      : --
    Connect Status     : up

3. Configure a VLAN MAC Ping test instance and start the test instance.

   # Configure Switch A.

   [SwitchA] nqa test-instance test macping
   [SwitchA-nqa-test-macping] test-type macping
   [SwitchA-nqa-test-macping] destination-address remote-mep mep-id 2
   [SwitchA-nqa-test-macping] md md1 ma ma1
   [SwitchA-nqa-test-macping] mep mep-id 1

   # Start the test instance.

   [SwitchA-nqa-test-macping] start now

4. Verify the configuration.

   Enter the MAC ping test instance view on Switch A and then run the display nqa results command. You can see that the test result is "success".

   [SwitchA-nqa-test-macping] display nqa results
   
    NQA entry(test, macping) :testflag is inactive ,testtype is macping
     1 . Test 1 result   The test is finished
