IP Address Assignment by the LCS60
PPP and SLIP users need to be assigned an IP address when they connect to the
LCS60, thereby allowing them to run TCP/IP applications over their serial con-
nection. Figure 1-5 describes IP address assignment; refer to Chapter 4 (PPP) or
Chapter 5 (SLIP) for more information.
Note: IP address assignment is defined in RFC1332.
The LCS60 has three mechanisms for assigning a SLIP or PPP user an IP address:
1 . Privately Administered Static IP Address. The user’s IP address is locally
administered by the user on his/her PC software package. The LCS60
will use the IP address requested by the PC package if it is valid and
unused.
2 . Reserved IP Address. This IP address, administered by the LCS60 adminis-
trator, is requested by specifying a zero IP address on the client software
package. A reserved IP address must exist in the LCS60 configuration
database before the session start up attempt.
3 . Dynamically Assigned IP Address. This IP address is randomly assigned by
the LCS60 from the IP network range associated with the particular IP
Network Security Group. A dynamic address may be requested on the
dialstring if no reserved IP address exists for a user ID.
Hardware Features
Enhanced Processor
The LCS60 offers the enhanced Motorola MVME197 processor, rated at 100+
MIPS. With this processor, the LCS60 can sustain a higher number of sessions at
a greater aggregate throughput than its LCS50E predecessor.
