Hello, my friend!
1.In FTTH, the OLT adds VenderTag for PITP packets; in FTTB, the ONU adds VenderTag for PITP packets and the OLT transparently transmits VenderTag information.
Configuring the ONU:
huawei(config)#pitp enable pmode
Configuring the OLT:
huawei(config)#pitp enable pmode
Disabling PITP for service ports of FTTB:
huawei(config)#pitp service-port index disable
2.In FTTH, the OLT does not add VenderTag for PITP packets; in FTTB, the ONU adds VenderTag for PITP packets and the OLT transparently transmits VenderTag information.
Configuring the ONU:
huawei(config)#pitp enable pmode
Configuring the OLT:
huawei(config)#pitp disable
3.In FTTH, the OLT adds VenderTag for PITP packets; in FTTB, the ONU works with the OLT to add VenderTag for PITP packets.
Configuring the ONU:
huawei(config)#pitp enable pmode
huawei(config)#raio-mode cntel-xpon pitp-pmode
Configuring the OLT:
huawei(config)#pitp enable pmode
huawei(config)#raio-mode cntel-xpon pitp-pmode
huawei(config)#pitp permit-forwarding service-port index enable
I hope it will be helpful for you. Thank you!
