| mop | Selects the Maintenance Operation Protocol (MOP) protocol. |
| none | Prevents any protocol selection on the line. This makes the port unusable by incoming connections. |
| pad | Selects X.3 PAD incoming connections. |
| rlogin | Selects the UNIX rlogin protocol. |
| telnet | Specifies all types of incoming TCP/IP connections. |
| all | Selects all protocols. Restores the default configuration. |
To determine the protocols that can be used for outgoing connections from a line, use the transport output line configuration command.
transport output {lat | none | pad | rlogin | telnet | all}| lat | Selects the Digital LAT protocol, which is the protocol used most often to connect routers to Digital hosts. |
| none | Prevents any protocol selection on the line. The system normally assumes that any unrecognized command is a host name. If the protocol is set to none, the system no longer makes that assumption. No connection will be attempted if the command is not recognized. |
| pad | Selects X.3 PAD, used most often to connect routers to X.25 hosts. |
| rlogin | Selects the UNIX rlogin protocol for TCP connections. The rlogin setting is a special case of Telnet. If an rlogin attempt to a particular host has failed, the failure will be tracked, and subsequent connection attempts will use Telnet instead. |
| telnet | Selects the TCP/IP Telnet protocol. It allows a user at one site to establish a TCP connection to a login server at another site. |
| all | Selects all protocols. |
To specify the transport protocol the Cisco IOS software uses if the user does not specify one when initiating a connection, use the transport preferred line configuration command.
transport preferred {lat | mop | nasi | none | pad | rlogin | telnet | v120}| all | Specifies all recognized protocols. |
| lat | Selects the Digital LAT protocol, which is the protocol used most often to connect routers to Digital hosts. |
| mop | Specifies the Maintenance Operation Protocol (MOP). |
| nasi | Specifies the NetWare Asynchronous Services Interface (NASI) protocol. |
| none | Prevents any protocol selection on the line. The system normally assumes that any unrecognized command is a host name. If the protocol is set to none, the system no longer makes that assumption. No connection will be attempted if the command is not recognized. |
| pad | Selects X.3 PAD, used most often to connect routers to X.25 hosts. |
| rlogin | Selects the UNIX rlogin protocol for TCP connections. The rlogin setting is a special case of Telnet. If an rlogin attempt to a particular host has failed, the failure will be tracked, and subsequent connection attempts will use Telnet instead. |
| telnet | Selects the TCP/IP Telnet protocol. It allows a user at one site to establish a TCP connection to a login server at another site. |
| v120 | Specifies asynchronous protocols over ISDN. |
To set the terminal transmit baud rate (to terminal), use the txspeed line configuration command.
txspeed bps| bps | Baud rate in bits per second (bps). |
To display an idle terminal message, use the vacant-message line configuration command. Use the no form of this command to remove the default vacant message or any other vacant message that may have been set.
vacant-message [d message d]| d | (Optional) A delimiting character of your choice--a pound sign (#), for example. You cannot use the delimiting character in the banner message. |
| message | (Optional) Vacant terminal message. |
To set the terminal screen width, use the width line configuration command. This command sets the number of character columns displayed on the attached terminal.
width characters| characters | Integer that specifies the number of character columns displayed on the terminal. |
