Checking WDM Interfaces

Checking WDM Interfaces

This section describes how to check the link layer on WDM interfaces.

Prerequisites

The Checking the Hardware is complete, and the NE40E works properly.

Procedure

  1. Run the display this interface command to view information about the optical module, alarm, error counters, and TTIs on the WDM interface.

    <HUAWEI> system-view
    [~HUAWEI] controller wdm 1/0/0
    [~HUAWEI-Wdm1/0/0] display this interface
    Description : HUAWEI, Quidway Series,Wdm1/0/0
    The Vendor PN is TRF5013FN-GA420 
    The Vendor Name is Opnext Inc.     
    Transceiver max BW: 10000~11300Mbps, Transceiver Mode: Single Mode
    WaveLength: 1310nm, Transmission Distance: 10km
    Rx Optical Power: -40.00dBm, normal range: [-14.400,  0.499]dBm
    Tx Optical Power:  -3.07dBm, normal range: [-6.001,  -1.000]dBm
    FEC Mode: standard
        OTN alarm:
            OTU layer:  R_LOS  R_LOF
            ODU layer:  PM-BDI  ODU-AIS  ODU-OCI  ODU-LCK
            OPU layer:  none
        WDM Error Counter:
            SM_BEI                :1966050
            PM_BEI                :1835071
            SM_BIP                :1966050
            PM_BIP                :1966050
            FEC 0 error           :776881
            FEC 1 error           :234854
            FEC 0 and 1 type error:0
            FEC symbol error      :252011
            FEC uncorrected error :491783522
            BER                   :0.000000000
        Received OTU TTI: ""
        Received ODU TTI: ""
        Received ODU TCM1 TTI: ""
        Received ODU TCM2 TTI: ""
        Received ODU TCM3 TTI: ""
        Received ODU TCM4 TTI: ""
        Received ODU TCM5 TTI: ""
        Received ODU TCM6 TTI: ""

    Under normal conditions, parameters (such as FEC, TTI) of WDM interfaces on the two ends of the NE40E are the same; there are no link alarms or errors.

  2. Run the ping command to test the connectivity of WDM link.

    <HUAWEI> ping 192.168.1.2
      PING 192.168.1.2: 56  data bytes, press CTRL_C to break
        Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms
        Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms
        Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms
        Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms
        Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms
    
      --- 192.168.1.2 ping statistics ---
        5 packet(s) transmitted
        5 packet(s) received
        0.00% packet loss
        round-trip min/avg/max = 1/23/113 ms

    In normal conditions, the ping operation should succeed.

Common Troubleshooting

The WDM interface is composed of a controller WDM interface and an Ethernet interface. If the physical layer of the Ethernet interface can not go Up, perform the following steps:

  1. Check whether parameters (such as FEC, TTI) of WDM interfaces on two ends of the NE40E are the same. If not, adjust configurations of WDM interfaces on two ends of the NE40E.

  2. Check the Ethernet interface according to "Common Troubleshooting" in Checking Ethernet Interfaces.

  3. If the fault persists, contact Huawei technical support personnel.
