Configuring
Bandwidth
Management for PPP
This section describes how to configure bandwidth management features
for dial-up lines.
Setting Normal Bandwidth
The -PORT NORMalBandwidth parameter specifies the amount of
bandwidth the port uses. The default normal bandwidth is usually
64 Kbps. Show the normal bandwidth for a port using:
SHow !<port> -PORT NORMalBandwidth
Set the normal bandwidth if required using:
SETDefault !<port> -PORT NORMalBandwidth = <kbps> (0)
Start here
Done
Unbind each serial path from its port:
SETDefault !4 -PATH DialCONTrol = DYNamic
SETDefault !5 -PATH DialCONTrol = DYNamic
Create a virtual port for each destination using their SysCallerIDs:
ADD !V1 -PORT VirtualPort SCID "Princeton"
ADD !V2 -PORT VirtualPort SCID "Andover"
ADD !V3 -PORT VirtualPort SCID "PaloAlto"
Set the normal bandwidth for each virtual port:
SETDefault !V1 -PORT NORMalBandwidth = 28.8
SETDefault !V2 -PORT NORMalBandwidth = 19.2
SETDefault !V3 -PORT NORMalBandwidth = 28.8
Create the dial number list for each virtual port:
ADD !V1 -PORT DialNoList "1-609-555-6000" Baud = 28.8 Type = Modem
ADD !V2 -PORT DialNoList "1-619-555-2222" Baud = 19.2 Type = Modem
ADD !V3 -PORT DialNoList "1-650-555-6969" Baud = 28.8 Type = Modem
Note: The baud rate set in the dial number list matches the baud rate of the lines available
to the port. The normal bandwidth determines how many lines of size 28.8 or 19.2 Kbps to
use. If there is no line of the correct baud available to a port, the port will use an available
line of the correct type.
Multiple destinations connect
with a dial pool.
