It is a very simple protocol used for transmission of IP datagrams across a serial line.
Perhaps you mean the "passive-interface" command in Cisco routers; what this does is that no information related to the routing protocol will be sent through the specified interface. For example, the interface that connects your network to the ISP should not carry any routing protocol information, since the routing protocol is only useful within your company's network.
PPPis more secure than SLIP. PPP uses two authetication Protocols : 1. Password Authetication Protocol (PAP) 2. Challenge Handshake Authetication Protocol (CHAP) So if you use SLIP on network that unauthorized user can gain acces to.

A serial port is an interface in which one bit of data is transmitted at a time.
When the interface is functioning as a DCE device
there may be the issue with the layer 2 protocol like hdlc or ppp is not configured or wrongly configured if the interface is serial interface.
SIP is an abbreviation of Serial Interface Protocol

There is a problem with the interface at the data-link layer that prevents it from functioning properly
The serial port must be configured for speed, parity type, character frame and protocol.
To change the line protocol from down to up, first ensure that the physical connection is intact and that the interface is enabled. You can do this by accessing the device's configuration mode (e.g., using a command-line interface) and issuing the command to enable the interface, such as no shutdown on Cisco devices. Additionally, check for any misconfigurations, link issues, or hardware failures that may be affecting the connection. Once these issues are resolved, the line protocol should come up.
HDLC
The FastEthernet interface of R1 is disabled. One of the default routes is configured incorrectly. A routing protocol is not configured on both routers. The default gateway has not been configured on both routers.
SerialLineInternetProtocol
To allow the subnet configured on that interface to be advertised through a dynamic routing protocol without having that interface participate in the protocol.
For CSLISP, the TCP header is reduced from about 20 characters to about 7. The actual data is not compressed, so you don't save very much in transmission costs per packet.
