R3303-HP 6600/HSR6600 Routers Layer 2 - WAN Command Reference Guide

67
Usage guidelines
If MP bundle is implemented through hardware (CPOS chip for example), the minimum MP packet size
for fragmentation varies with chips (the fragment size on certain chips can only be 128, 256, and 512
bytes). In this case, make sure the setting configured with the ppp mp min-fragment command conforms
to the hardware specifications for the MP bundle to be created and the sub-channel LCP link to be
established successfully.
After executing the ppp mp min-fragment command, you must re-enable all the bound ports (by using
the shutdown and undo shutdown commands) for the new setting to take effect.
Examples
# Set the minimum MP packet size for fragmentation to 500 bytes.
<Sysname> system-view
[Sysname] interface virtual-template 0
[Sysname-Virtual-Template0] ppp mp min-fragment 500
ppp mp mp-group
Use ppp mp mp-group to add the current interface to an MP-group.
Use undo ppp mp to remove the current interface from the specified MP-group it belongs to.
Syntax
ppp mp mp-group mp-number
undo ppp mp
Views
Interface view
Default command level
2: System level
Parameters
mp-number: MP-group interface number.
• 6602 routers support one-dimensional MP-group interface numbers in the range of 0 to 1023.
• HSR6602, 6604, 6608, and 6616 routers support three-dimensional MP-group interface numbers,
in the format of X/Y/Z:
{ X indicates the number of the slot where the base card resides. The value range depends on the
device model.
{ Y indicates the number of the slot where the subcard resides. The value range depends on the
device model.
{ Z indicates the interface number on the subcard. The value range is 0 to 1023.
Usage guidelines
This command should be used together with the interface mp-group command. However, the order in
which the two commands are executed can be either one. You can create an MP-group interface and
then add an interface to the MP-group; or add the interface to the MP-group and then create the
MP-group.
You can add only physical interfaces to an MP group. Logical interfaces (such as Tunnel interfaces) do
not support the ppp mp mp-group command.
