Examples
# Specify the AC name for the PPPoE server on GigabitEthernet 1/0/1 as pppoes.

[Sysname-GigabitEthernet1/0/1] pppoe-server tag ac-name pppoes
pppoe-server tag ppp-max-payload
Use pppoe-server tag ppp-max-payload to enable the PPPoE server to support the ppp-max-payload tag
and specify a range for the tag.
Use undo pppoe-server tag ppp-max-payload to restore the default.
Syntax
pppoe-server tag ppp-max-payload [ minimum minvalue maximum maxvalue ]
undo pppoe-server tag ppp-max-payload
Default
The PPPoE server does not support ppp-max-payload tag. It ignores the ppp-max-payload tag in PADI or
PADS packets from clients, and returns a PADO or PADS packets without the ppp-max-payload tag.

Parameters
minimum minvalue: Specifies the minimum value for the PPP maximum payload, in the range of 64 to
4470 bytes. The default value is 1492 bytes.
maximum maxvalue: Specifies the maximum value for the PPP maximum payload, in the range of 64 to
4470 bytes. The default value is 1500 bytes. The maxvalue argument must be equal or larger than the
minvalue argument.
Usage guidelines
This command enables the PPPoE server to forward large PPP packets with a payload larger than 1492
bytes and reduces fragmentation. If the ppp-max-payload tag sent by the PPPoE client is within the tag
range, the PPPoE server returns a PADO or PADS packet that includes the tag. If not, the PPPoE server
considers the received packets invalid, and it does not return a PADO or PADS packet.
The jumboframe enable command can change the size of jumbo frames supported by the interface. The
maximum size of the jumbo frames configured by the jumboframe enable command should be larger
than the maximum value configured by the pppoe-server tag ppp-max-payload command.
Examples
# Enable the PPPoE server to support the ppp-max-payload tag and specify the value for the PPP
maximum payload to be in the range of 1494 to 1580 bytes.
