Tcp Service Ports; Serial Line Ip (Slip) - HP LCS60 Installation Manual

Remote Access Protocols
The TCP gateway sessions take advantage of the highly efficient fiber interface
between the LCS60 and the data switch. With this service, any TCP/IP host that
can be reached on the LAN is accessible from the data switch network. For LAN
users, connection is generally provided through a DESTINATION: prompt, how-
ever, a TCP service port can be customized to bypass this prompt and automati-
cally connect the LAN user directly to a particular data switch end point.
Refer to Chapter 7 for configuration of gateway services.

TCP Service Ports

A TCP service port is identified by a port number and can be customized to
streamline the transition from the TCP/IP network to the data switch network.
These ports can be configured with predefined destinations (PDDs), disconnect
options, window size changes, time limit options for the DESTINATION: prompt
and for data transmission, and customized destination prompts.
The number of TCP service ports is 500; each port can be defined with a unique
PDD offering the administrator enhanced flexibility in terms of the number of
data switch network connected hosts than can be contacted by each LCS60.

Serial Line IP (SLIP)

The LCS60 provides SLIP protocol capability to enhance dial-in access through
the data switch network. SLIP enables remote users to gain access to their inter-
net and use familiar TCP/IP commands for most applications, e.g., file transfer,
electronic mail, and remote login.
SLIP allows a remote PC or Macintosh to logically reside on the TCP/IP LAN. In
a SLIP session, a remote user can dial into an LCS60, request SLIP service, and
receive an IP address automatically. This remote user is then logically connected
to the LAN and can execute such TCP/IP commands as ftp, telnet, and ping.
With the capability for automatic assignment of IP addresses, the LCS60 main-
tains a database of used addresses and the LCS60 administrator does not have to
pre-assign IP addresses to users. Static assignment of these addresses is still pos-
sible, however, for any situation where it may be necessary.
