H3C MSR810 - Pppoe-Server Tag Ppp-Max-Payload

86
Examples
# Specify the AC name for the PPPoE server on GigabitEthernet 1/0/1 as pppoes.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[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 set a range for the tag on an interface.
Use undo pppoe-server tag ppp-max-payload to restore the default.
Syntax
pppoe-server tag ppp-max-payload [ minimum min-number maximum max-number ]
undo pppoe-server tag ppp-max-payload
Default
The PPPoE server does not support ppp-max-payload tag on an interface. The PPPoE server
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 min-number: Specifies the minimum value for the PPP maximum payload, in the range of
64 to 4470 bytes. The default value is 1492 bytes.
maximum max-number: Specifies the maximum value for the PPP maximum payload, in the range
of 64 to 4470 bytes. The default value is 1500 bytes. The max-number argument must be equal or
greater than the min-number 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 i t 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 set the value for the PPP
maximum payload to be in the range of 1494 to 1580 bytes on GigabitEthernet 1/0/1.
