DHCP Option 82 can be enabled or disabled at four levels: global, port, VLAN,
and service port levels. This function takes effect only after it is enabled at the
four levels. Among the four levels, DHCP Option 82 is disabled only at the global
level by default.
– The global level: In global config mode, run the dhcp option82 command to
enable DHCP Option 82 at the global level.
When you run this command, select the enable, forward, or rebuild
parameter based on site requirements. The three parameters can all enable
DHCP Option 82 but provide different packet processing policies on the OLT.
For details, see the dhcp option82 command.
– The port level: In global config mode, run the dhcp option82 port or dhcp
option82 board command to enable DHCP Option 82 at the port level.
– The VLAN level:
a. In global config mode, run the vlan service-profile command to create
a VLAN service profile.
b. Run the dhcp option82 enable command to enable DHCP Option 82 at
the VLAN level.
c. Run the commit command to make the profile configuration take effect.
d. Run the quit command to quit the VLAN service profile mode.
e. Run the vlan bind service-profile command to bind the created VLAN
service profile to a VLAN.
– The service port level: In global config mode, run the dhcp option82 service-
port command to enable DHCP Option 82 at the service port level.
2. On the OLT, run the dhcp-option82 permit-forwarding service-port command
with the enable parameter selected, to allow ONU DHCP packets to carry Option
82 information.
– Enable Policy Information Transfer Protocol (PITP) on both the OLT and ONUs. This
configuration is recommended for the PPPoE-based Internet access service.
1. Enable PITP on both the OLT and ONUs.
PITP can be enabled or disabled at four levels: global, port, VLAN, and service
port levels. This function takes effect only after it is enabled at the four levels.
Among the four levels, PITP is disabled only at the global level by default.
– The global level: In global config mode, run the pitp enable pmode, pitp
forward pmode, or pitp rebuild pmode command to enable PITP at the
global level.
In the preceding commands, the enable, forward, and rebuild parameters
can all enable PITP but provide different packet processing policies on the
OLT. Select one of them based on site requirements. For details, see the
pitp command.
– The port level: In global config mode, run the pitp port or pitp board
command to enable PITP at the port level.
– The VLAN level:
a. In global config mode, run the vlan service-profile command to create
a VLAN service profile.
