R2511-HP MSR Router Series Layer 2 - WAN Command Reference(V5)

35
After executing the ppp mp min-fragment command, you must re-enable all the bundled 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 by its number in the range of 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.
Examples
# Add interface Serial 2/0 to MP-group 3.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] ppp mp mp-group 3
ppp mp short-sequence
Use ppp mp short-sequence to trigger MP short sequence number header format negotiation. After the
negotiation succeeds, the local end receives packets with short sequence numbers.
Use undo ppp mp short-sequence to restore the default.
Syntax
ppp mp short-sequence
undo ppp mp short-sequence
