How to configure Clock Synchronization?
Configuring Clock Synchronization
In this scenario, the E1/STM-1 line clock can be used to achieve network-wide clock synchronization.
Prerequisites
The clock daughter board CKMC/CKMD must be on the SCU main control board.
Context
Configuration roadmap for clock synchronization:
1.The OLT traces the upstream E1/STM-1 line clock of the TOPA board as the system clock.
2.The system clock is delivered to an ONU through optical paths of the GPON board.
3.The ONU uses the line clock of the GPON upstream port as the system clock.
4.The ONU E1 transmit clock is synchronized with the system clock of the ONU.
Procedure
Configure a clock on the OLT.
Add a system clock source.
Run the clock source command to configure the line clock of E1/STM-1 port 0/5/0 on the TOPA board as the system clock source. Set the ID of the clock source to 0.
The clock module automatically judges the type of the specified clock source (E1/STM-1) and selects a reference source for phase lock based on priorities.
huawei(config)#clock source 0 0/5/0
Configure a priority for the system clock source.
Run the clock priority command to set the priority of clock source 0 to the highest priority.
huawei(config)#clock priority system 0
Query configurations and the status of the system clock source.
Run the display clock source system command to query configurations and the status of the clock source. Ensure that configurations of the system clock source are correct and the status is Normal.
huawei(config)#display clock source system ------------------------------------------------------------------------------ Index Board Source Clk-type State Priority QL Selected ------------------------------------------------------------------------------ 0 H801TOPA 0/5/0 E1 Normal 0 --- YES ------------------------------------------------------------------------------
Run the display clock mode command to query the clock working mode. Ensure that the clock daughter board works in tracing mode.
huawei(config)#display clock mode Clock manage-mode:Third-mode Clock subboard work-mode:Tracing
Configure a clock on the ONU.
Configure the GPON line clock as the system clock.
The system clock of the OLT is delivered to the ONU through the GPON port on the OLT, achieving clock synchronization between the OLT and the ONU.
Run the clock source command to configure the clock recovered from the GPON upstream port as the system clock of the ONU.
Run the clock priority command to configure the priority of the clock source.
huawei(config)#clock source 0 0/0/1 Clock source set succeeded huawei(config)#clock priority system 0
Configure the system clock as the transmit clock for an E1 port.
Run the interface tdm command to enter the E1 port configuration mode.
Run the tx clock or port portid udt system command to configure the system clock as the transmit clock of the port.
Run the display port state command to query the transmit clock of the E1 port.
huawei(config)#interface tdm huawei(config-if-tdm-)#port 0 udt system huawei(config-if-tdm-)#display port state 0 --------------------------------------- Port : 0 State : normal Mode : UDT Code : HDB3 Looptype : - Timeslot : - Clock : system CRC4 : - Signaling : - ESF : - Impedance : 120 Ohm ---------------------------------------
Query configurations and the status of the system clock source.
Run the display clock source command to query configurations and the status of the system clock source.
huawei(config-if-tdm-)#quit huawei(config)#display clock source --------------------------------------------------------------- Index Config Type Source State Priority Output --------------------------------------------------------------- 0 YES line 0/0/1 Normal 0 YES 1 NO -- -/ -/ - --- --- --- 2 NO -- -/ -/ - --- --- --- 3 NO -- -/ -/ - --- --- --- 4 NO -- -/ -/ - --- --- --- 5 NO -- -/ -/ - --- --- --- 6 NO -- -/ -/ - --- --- --- 7 NO -- -/ -/ - --- --- --- 8 NO -- -/ -/ - --- --- --- 9 NO -- -/ -/ - --- --- --- ---------------------------------------------------------------
Huawei MA5620 Series Equipment Port Mirror Capture
Case Information:
Huawei MA5620 series equipment, as the FTTB and FTTC mainstream products, which take up mainstream position in GPON network. So for this kind of equipment also is especially critical of troubleshooting. Based on the relatively new software version of this type of equipment as entry point, which carry with port mirroring function when leave factory. Using of dealing with the data communication equipment caught ideas to deal with PON equipment failure. Let the underlying each port data show in front of engineers, for the whole network packet flow are analyzed, to facilitate fault processing.
Precondition:
1.Can entry ONU equipment configuration interface layout data.
2.Software release is V8R312 above.
3.Install similarly Wireshark data package to capture software.
Operating steps:
1.Connect beaching accommodation
user：root password：mduadmin
This is factory default account and password of the series of huawei equipment.
The way of logging in:
a. Through OLT equipment configuration interface using Telnet login ONU (configured remote management VLAN and device address);
b. Use the Console line through equipment management con landing interface equipment, connection go into here, the details please check this site “MA5600 OLT equipment upgrade instructions” on the Console line connection of the materials for equipment;
c. Through the Internet directly, landing ONU equipment reserved address
When the equipment leave factory, 0/1 in FE / 1 mouth have a meth port address, the address is:
#
[meth]
<meth0> interface meth0 ip address 10.11.104.2 255.255.255.0 #
Through cable directly connect to PC, Configuration for the 10.11.104. X addresses of IP addresses, and communicate with ONU equipment, can use Telnet protocol on the device.
2.Mirroring configuration
Legend:
System configuration only supports a mirror the destination port.
Multiple ports can be mirrored to the same destination port.
GPON upward port can be mirrored to FE with registered permanent residence; Can’t use FE account mirrored to GPON upward.
Configuration date:
a.Use mirror port command with Ethernet port mirroring port.
b.Use the display mirror command queries Ethernet port mirror configuration.
Example:
eg.All the transceiver two-way message 0/1/1 port mapping to 0/1/3 ports
huawei(config)# diagnose huawei(diagnose)%%mirror port 0/1/1 0/1/3 all huawei(diagnose)%%display mirror ------------------------------------------------ Source port Direction Destination port ------------------------------------------------ 0/ 1/ 1 all 0/ 1/ 3 ------------------------------------------------
eg.The 0/0/1 gpon port transceiver two-way message are mapped to 0/1/8 ports.
huawei(config)# diagnose huawei(diagnose)%%mirror port 0/0/1 0/1/8 all huawei(diagnose)%%display mirror ------------------------------------------------ Source port Direction Destination port ------------------------------------------------ 0/ 0/ 1 all 0/ 1/ 8 ------------------------------------------------
Correction operate
Delete the Ethernet port mirroring
undo mirror port
3.Capture data packet
When configured mirror port parameters, the image can be destination port are connected by a cable to capture packets PC, the PC run similar to the Wireshark’s software of capturing packet, will receive numerous underlying data packets.
