LCS60 Configuration and Connection for SLIP Service

SLIP Service Connection Dialstrings

One of the following types of dialstrings (shown with the area/exch/name from the example in Figure 5-1) may be used:

DESTINATION: mlkway/earth/morse.slip

DESTINATION: mlkway/earth/morse.slip..-m512:-q1:-v16

DESTINATION: mlkway/earth/morse.slip..-D

DESTINATION: mlkway/earth/morse.slip..154.12.23.10

The options for these dialstrings are described below:

-mN

Specifies the maximum transmission unit (MTU) that the SLIP

 

 

connection can transport. The default SLIP MTU is 1006; the

 

 

MTU value must satisfy: 296 ≤ N ≤ 1006.

 

-qN

Specifies whether priority queueing is enabled (1) or disabled

 

 

(0). By default, priority queueing is enabled. In priority queue-

 

 

ing, IP datagrams are marked as either interactive or non-

 

 

interactive; interactive datagrams are always queued in front of

 

 

non-interactive datagrams. The queue is located between the IP

 

 

protocol and the data switch, therefore, priority queueing only

 

 

affects datagrams flowing from the LCS60 to the data switch.

 

-vN

Specifies the number of Van Jacobson TCP/IP header compres-

 

 

sion slots to use. The default is 16; the number of slots must

 

 

satisfy: 3 ≤ N ≤ 64. (Refer to the section Van Jacobson TCP/IP

 

 

Header Compression in Chapter 1.)

 

-D

Specifies that the user be assigned an IP address dynamically

 

 

(rather than use his/her reserved IP address) provided a negoti-

 

 

able IP address has been administered in his/her client software

 

 

package. Without the -Doption, the reserved IP address for the

SLIP

 

user is assigned provided it exists and is not already in use.
