Configuring GPON Type B Dual-Homing (OLT Dual-Homing)

Configuring GPON Type B Dual-Homing (OLT Dual-Homing)

This chapter introduces the configuration guide of GPON Type B dual-homing protection.

Prerequisites

  • The Layer 3 switch support cluster and layer 2 isolation.
  • The ONU is added to the OLT.
  • An ONU has been added to the active and standby OLTs by running the ont add command. All ONU profiles, such as DBA profile and line profiles, are the same on the active and standby OLTs.

Usage Scenario

GPON Type B Dual-Homing ( OLT Dual-Homing ):

NOTE:
GPON Type B Dual-Homing ( OLT Dual-Homing ):
  • L3 switch support cluster.
  • OLT Upstream link run LAG (Link Aggregation Group ).
  • When OLT an upstream link is interrupted, The whole OLT does not need to be switched.
  • Layer 2 isolation is configured between the L3 switch and the OLT .

  • Standby Port: 0/4/0
NOTE:

Data planning for example data, the actual service configuration, please use the specific network data planning.

Procedure

  1. Configure primary OLT huawei_A.
    1. Configure link aggregation.

      To add upstream ports 0/3/0 and 0/4/0 into a lacp static aggregation group in ingress mode.

      huawei_A(config)#link-aggregation 0/3/0 0/4/0 ingress workmode lacp-static

    2. Run the dual-parenting local-node command to configure the local IP address, TCP port number, and key.

      huawei_A(config)#dual-parenting local-node ip-address 192.168.68.5 port 6076 key 42340000

    3. Run the dual-parenting peer-node command to configure the peer IP address, TCP port number, and key.

      huawei_A(config)#dual-parenting peer-node standby ip-address 192.168.78.8 port 6076 key 42340000

    4. Run the dual-parenting sync command to enable dual-homing synchronization.

      huawei_A(config)#dual-parenting sync enable

    5. Run the protect-group command to create a protection group.

      huawei_A(config)#protect-group 1 protect-target gpon-uni-port workmode dual-parenting

    6. Run the protect-group member command to add a member to the protection group, the type of the member is work.

      huawei_A(protect-group-1)#protect-group member port 0/1/0 role work
      NOTE:

      After a member is added to a dual-homing protection group, the group is automatically enabled.

    7. Run the peer-group-member command to configure the peer member of the protection group.

      huawei_A(protect-group-1)#peer-group-member peer-node standby peer-port 0/1/0

    8. Run the uplink-monitor port command to associate the protection groups with the uplink port status.

      NOTE:

      If an Ethernet link aggregation group has been configured, make sure that the Ethernet port associated with the dual-homing protection groups is the master port in the aggregation group.

      huawei_A(protect-group-1)#uplink-monitor port 0/3/0
      huawei_A(protect-group-1)#quit
      

    9. Run the onu-switch notify command to globally configure the function of sending gratuitous ARP packets for users after an ONU switchover.

      This function is disabled by default.
      huawei_A(config)#onu-switch notify ipv4 enable

    10. Save the data.

      huawei_A(config)#save

  2. Configure secondary OLT huawei_B.

    huawei_B(config)#link-aggregation 0/3/0 0/4/0 ingress workmode lacp-static
    huawei_B(config)#dual-parenting local-node ip-address 192.168.78.8 port 6076 key 42340000
    huawei_B(config)#dual-parenting peer-node active ip-address 192.168.68.5 port 6076 key 42340000
    huawei_B(config)#dual-parenting sync enable
    huawei_B(config)#protect-group 1 protect-target gpon-uni-port workmode dual-parenting
    huawei_B(protect-group-1)#protect-group member port 0/1/0 role protect
    huawei_B(protect-group-1)#peer-group-member peer-node active peer-port 0/1/0
    huawei_B(protect-group-1)#protect-group enable
    huawei_B(protect-group-1)#uplink-monitor port 0/3/0
    huawei_B(protect-group-1)#quit
    huawei_B(config)#onu-switch notify ipv4 enable
    huawei_B(config)#save

  3. (Option) Configure L3 Switch.

    Taking Huawei S12700 switch as an example.

    1. Configure port isolate mode to Layer 2 isolation.

      [SwitchA]port-isolate mode l2

    2. Create Eth-Trunk and configura Eth-Trunk mode.

      <SwitchA> system-view
      [SwitchA] interface eth-trunk 1
      [SwitchA-Eth-Trunk1] mode lacp   //Configure Eth-Trunk 1 to work in LACP mode.
      [SwitchA-Eth-Trunk1] port link-type trunk   //Set the link type of Eth-Trunk1 to trunk.
      [SwitchA-Eth-Trunk1] port trunk allow-pass vlan 2 to 4094   //Add Eth-Trunk1 to VLANs 2 to 4094.
      [SwitchA-Eth-Trunk1] port-isolate enable group 1   //Enable Layer 2 isolation.
      

    3. Add port to Eth-Trunk.

      Run the eth-trunk command adds an interface to an Eth-Trunk.

      [SwitchA] interface gigabitethernet 1/0/3
      [SwitchA-GigabitEthernet1/0/3] eth-trunk 1
      [SwitchA-GigabitEthernet1/0/3] quit
      [SwitchA] interface gigabitethernet 1/0/4
      [SwitchA-GigabitEthernet1/0/4] eth-trunk 1
      [SwitchA-GigabitEthernet1/0/4] quit
      

Result

Verify the configuration.
