PPP
Ensure that other port parameters (such as speed, parity, and flow control) are
Note:
properly configured for the connection.
2 Create a site for the outgoing multilink PPP connection.
Local>> DEFINE SITE irvine
All other desired site parameters should be set up, and a static route should be
Note:
defined for the site, before the site is used for connections.
Configure the ports associated with the multilink site.
3
A Associate the site with two or more ports, giving each port a priority. Higher priority ports will
be used first.
Local>> DEFINE SITE irvine PORT 1 PRIORITY 1
Local>> DEFINE SITE irvine PORT 2 PRIORITY 2
Local>> DEFINE SITE irvine PORT 3 PRIORITY 3
Local>> DEFINE SITE irvine PORT 4 PRIORITY 4
Estimate the bandwidth of each port associated with the site.
B
The estimate should be based on the fastest data transfer that the attached modem can support,
adjusted for expected compression.
The following example assumes a 28.8 kbps modem attached to port 2 with about a 2:1
compression rate (28800 x 2 = 57600 bps = 5760 bytes per second, rounded to 5800 bytes per
second).
Local>> DEFINE SITE irvine PORT 2 BANDWIDTH 5800
See Estimate Each Port's Bandwidth on page 5-6 for in-depth instructions on calculating
bandwidth amounts.
C Specify a telephone number for each port.
When the site is brought up, the SCS will attempt a connection by dialing the telephone number
associated with the highest priority port (in this case, 555-1001).
Local>> DEFINE SITE irvine PORT 1 TELEPHONE 555-1001
Local>> DEFINE SITE irvine PORT 2 TELEPHONE 555-1002
Local>> DEFINE SITE irvine PORT 3 TELEPHONE 555-1003
Local>> DEFINE SITE irvine PORT 4 TELEPHONE 555-1004
4 Configure the site bandwidth parameters.
The SCS will only modify bandwidth if it initiated the connection.
