This chapter describes the function and displays the syntax for the commands for setting operating characteristics for remote terminal service connections. For more information about defaults and usage guidelines, see the corresponding chapter of the Dial Solutions Command Reference.
To set the interval for closing the connection, use the absolute-timeout line configuration command. Use the no form of this command to restore the default.
absolute-timeout minutes| minutes | The number of minutes after which the user's session will be terminated. |
To enable enhanced editing mode for a particular line, use the editing line configuration command. Use the no form of this command to disable the enhanced editing mode.
editingTo enable password checking at login, use the login line configuration command. Use the no form of this command to disable password checking and allow connections without a password.
login [local | tacacs]| local | (Optional) Selects local password checking. Authentication is based on the username specified with the username global configuration command. |
| tacacs | (Optional) Selects the Terminal Access Controller Access Control System (TACACS)-style user ID and password-checking mechanism. |
To enable AAA/TACACS+ authentication for logins, use the login authentication line configuration command. Use the no form of the command to return to the default.
login authentication [default | list-name]| default | Uses the default list created with the aaa authentication login command. |
| list-name | Use the list specified. |
To specify a password on a line, use the password line configuration command. Use the no form of this command to remove the password.
password password| password | Character string that specifies the line password. The first character cannot be a number. The string can contain any alphanumeric characters, including spaces, up to 80 characters. You cannot specify the password in the format number-space-anything. The space after the number causes problems. For example, hello 21 is a legal password, but 21 hello is not. The password checking is case sensitive. For example, the password Secret is different than the password secret. |
To set the terminal receive speed (how fast the terminal receives information from the modem), use the rxspeed line configuration command.
rxspeed bps| bps | Baud rate in bits per second (bps). |
To set the maximum number of terminal sessions per line, use the session-limit line configuration command. Use the no form of this command to remove any specified session limit.
session-limit session-number| session-number | Specifies the maximum number of sessions. |
To set the interval for closing the connection when there is no input or output traffic, use the session-timeout line configuration command. Use the no form of this command to remove the timeout definition.
session-timeout minutes [output]| minutes | Specifies the timeout interval in minutes. |
| output | (Optional) Specifies that when traffic is sent to an asynchronous line from the router (within the specified interval), the connection is retained. |
To obtain information about the terminal configuration parameter settings for the current terminal line, use the show terminal EXEC command.
show terminalTo set the terminal baud rate, use the speed line configuration command. This command sets both the transmit (to terminal) and receive (from terminal) speeds.
speed bps| bps | Baud rate in bits per second (bps). The default is 9600 bps. |
To set the flow control start character, use the start-character line configuration command. Use the no form of this command to remove the character.
start-character ascii-number| ascii-number | Decimal representation of the start character. |
To define which protocols to use to connect to a specific line of the router, use the transport input line configuration command.
transport input {all | lat | mop | nasi | none | pad | rlogin | telnet | v120}| all | Selects all protocols. Restores the default configuration. |
| lat | Selects the Digital LAT protocol and specifies both incoming reverse LAT and host-initiated connections. |
| mop | Selects Maintenance Operation Protocol (MOP). |
| nasi | Select NetWare Access Servers Interface (NASI) as the input transport 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. |
| v120 | Select the V.120 protocol for incoming async over ISDN connections. |
To determine the protocols that can be used for outgoing connections from a line, use the transport output line configuration command.
transport output {all | lat | mop | nasi | none | pad | rlogin | telnet | v120}| all | Selects all protocols. |
| lat | Selects the Digital LAT protocol, which is the protocol used most often to connect routers to Digital hosts. |
| mop | Selects Maintenance Operation Protocol (MOP). |
| nasi | Select NetWare Access Server Interface (NASI) as the output transport 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 | Select the V.120 protocol for outgoing asynchronous over ISDN connections. |
To specify the transport protocol that 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 {all | 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 Access Server 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 is 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 part of the Telnet protocol. If an rlogin attempt to a particular host fails, the failure is 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 speed (how fast the terminal sends information to the modem), use the txspeed line configuration command.
txspeed bps| bps | Baud rate in bits per second (bps). |
