The PITP function can be enabled or disabled at two levels. The PITP function is enabled only
when it is enabled at both levels.
1.
Global PITP function: Run the
pitp enable pmode
command to enable global PITP P mode.
By default, the global PITP function is disabled.
In the PITP V mode, run the
pitp vmode ether-type
command to set the Ethernet protocol
type to be the same as that of the BRAS. Then, run the
pitp enable vmode
command to
enable global PITP V mode.
NOTE
The Ethernet protocol type of the PITP V mode must be configured when the PITP V mode is disabled.
2.
(Optional) VLAN-level PITP function:
a.
Run the
vlan service-profile
command to create a VLAN service profile and enter
the VLAN service profile mode.
b.
Run the
pitp enable
command to enable the PITP function of the VLAN. By default,
the PITP function of the VLAN is enabled.
c.
Run the
commit
command to make the profile configuration take effect. The
configuration of the VLAN service profile takes effect only after this command is
executed.
d.
Run the
quit
command to quit the VLAN service profile mode.
e.
Run the
vlan bind service-profile
command to bind the VLAN service profile
configured in
to the VLAN.
Step 3
Configure the optional attributes of PITP.
l
Run the
pitp permit-forwarding service-port
command to set whether the service port
allows the user-side PPPoE packet carrying the vendor tag information. By default, this
function is disabled, that is, the user-side PPPoE packet carrying the vendor tag information
is not allowed.
The system adds a tag containing the device name, shelf ID, slot ID, and port ID to the PPPoE
+ upstream PADI and PADR packets to generate new packets. If this function is enabled,
tagged packets are forwarded. If this function is disabled, tagged packets are discarded.
When the PITP function is applied to the OLT+MA5616 network, pay attention to the
following points:
1.
When the PITP function is enabled only on the OLT, the tag of the PADI packet contains
only the information about the PON port on the OLT.
2.
When the PITP function is enabled only on the MA5616, the tag of the PADI packet
contains only the information about the user port on the MA5616.
3.
If the PITP function is enabled on both the OLT and the MA5616, a function (through
the
pitp permit-forwarding service-port
command) is used to choose which tag the
PADI packet carries.
–
When this function is enabled, the tag of the PADI packet contains only the
information about the PON port on the OLT.
–
When this function is disabled, subscribers connected to the service port fail to dial
a number. That is, the PADI packet (PITP P mode) cannot be transmitted.
l
Run the
raio sub-option 0x90
command to configure PITP sub-option 90. By default, PITP
sub-option 90 is disabled.
The PPPoE+ mode supports reporting the sub-option 90 line parameters, including link type
and encapsulation information. Enable or disable PITP sub-option 90 according to actual
SmartAX MA5616 Multi-service Access Module
