Command Reference Guide Chapter 1 PPP and MP Configuration Commands
3Com Corporation
1-16
Description
In a dial application where multiple links are required to carry services, it is necessary to
allow a packet trigger to call up multiple links to guarantee the minimum bandwidth
needed.
Use the ppp mp min-bind command to configure the minimum number of PPP links
that an MP bundle must have.
Use the undo ppp mp min-bind command to restore the default when a call requires
only one PPP link.
By default, no lower limit of links is set for MP bundling.
Note that, after you configure the ppp mp min-bind command, the router does not look
at the ratio of traffic to bandwidth when making calls to bring up links. As for links that
already exist, they are not torn down because of timeout. The ppp mp min-bind
command voids the dialer timer idle command, just as the dialer threshold 0
command would.
The argument min-bind-num must be less than max-bind-num.
Related command: dialer threshold, ppp mp.
Example
# Set the minimum number of channels an MP bundle must have to 4.
[3Com-dialer0] ppp mp min-bind 4
# Remove the minimum number of channels setting you set.
[3Com-dialer0] undo ppp mp min-bind
1.1.18 ppp mp min-fragment
Syntax
ppp mp min-fragment size
undo ppp mp min-fragment
View
Virtual template interface view
Parameter
size: Minimum packet size for MP outgoing packet fragmentation. When the MP
outgoing packet is smaller than this value, fragmentation is avoided. When the MP
packet is larger than this value, fragment is involved. It is in byte in the range from 128
to 1500.
