OSN 500 550 580 V100R008C50 Commissioning and Configuration Guide 02

Procedure

1. Select the corresponding navigation path and check the related board parameters.
   1. Check the SDH board parameters. For the SDH board parameters, see Table 1-3.
      Table 1-3  SDH board parameters

      Board Type	Parameter	Navigation Path	Application Scenario
      SDH	Laser Switch	In the NE Explorer, select a board. Choose Configuration > SDH Interface from the Function Tree. Click By Board/Port(channel) and select Port from the drop-down list.	When configuring MSP shared services on an optical interface of a board, enable this parameter.
      			When configuring services on an optical interface of a board, enable this parameter.
      	Optical(Electrical)Interface Loopback		Non-loopback: It is the normal state. When the equipment runs normally, set this parameter to non-loopback. Inloop: The loop is performed toward the local NE. Outloop: The loop is performed toward the opposite NE. Inloop and outloop of an optical interface affect services. They are used to locate faults.

   2. Check the PDH board parameters. For the PDH board parameters, see Table 1-4.
      Table 1-4  PDH board parameters

      Board Type	Parameter	Navigation Path	Application Scenario
      PDH	Tributary Loopback	In the NE Explorer, select a board. Choose Configuration > PDH Interface from the Function Tree. Click By Board/Port(channel) and select Port from the drop-down list.	Non-loopback: It is the normal state. When the equipment runs normally, set this parameter to non-loopback. Inloop: When input service signals reach the tributary board of the target NE, the signals revert to the original trail. This function is used to locate faults of each service path. Outloop: When input service signals reach the tributary board through the input port of the local NE, the signals are looped back directly to the service output end.
      	Service Load Indication		Non-loaded: The service path does not process the services that are carried, to suppress alarms in non-loaded service paths. Load: The service path processes the services that are carried. In the case of a tributary board that has services, set this parameter to Load.

   3. Check the data board parameters. For the data board parameters, see Table 1-5.
      Table 1-5  Data board parameters

      Board Type	Parameter	Navigation Path	Application Scenario
      Ethernet	Enabled/Disabled	In the NE Explorer, select a board. Choose Configuration > Ethernet Interface Management > Ethernet Interface from the Function Tree. Click External Port. Click the Basic Attributes tab.	When configuring Ethernet board port services, set the port to Enabled.
      	Working Mode		Set the working mode of Ethernet ports according to networking configuration requirements.
      	Maximum Frame Length		When a packet exceeds the maximum frame length that is set, the packet is discarded or the data with the maximum frame length is extracted from the frame and then transmitted. By default, the value is set to 1522, unless otherwise specified.
      	MAC Loopback		Non-loopback: It is the normal state. When the equipment runs normally, set this parameter to non-loopback. Inloop: Inside the equipment, services from the cross-connect side are looped back to the cross-connect side. This operation affects services configured on ports and is used to locate faults.
      	PHY Loopback		Non-loopback: It is the normal state. When the equipment runs normally, set this parameter to non-loopback. Inloop: Inside the equipment, services from the cross-connect side are looped back to the cross-connect side. This operation affects services configured on ports and is used to locate faults.
      	TAG	In the NE Explorer, select a board. Choose Configuration > Ethernet Interface Management > Ethernet Interface from the Function Tree. Click External Port. Click the TAG Attributes tab.	Tag Aware: If the client-side equipment sends tagged packets, set the TAG attribute of external ports to Tag Aware. Access: If the client-side equipment sends untagged packets, set the TAG attribute of external ports to Access. Hybrid: If the client-side equipment sends tag and untagged packets, set the TAG attribute of external ports to Hybrid.
      	Entry Detection		This parameter is used to identify tags in data packets. During the configuration of VLAN services, set this parameter to Enabled.

2. Change the values of the board parameters according to service planning and actual board configurations. For details, see Modifying Board Configuration Parameters.
