This chapter describes the commands for system interfaces, system booting, and terminal sessions. The system interface commands display the router configuration in various forms using the show commands. The system booting commands are used to reboot the router, download software, and reset configuration value to their defaults. The terminal session commands manage communications between an ASCII terminal or a PC running terminal emulation software and the router. (The Cisco 700 Series Installation Guide provides instructions for connecting a terminal to the router.)
To create a profile, enter an existing profile, or return to system mode, use the cd command (also known as the change user command).
CD [username]
username | Profile name. |
System or profile mode
This command creates a profile if the user name does not exist or moves to the specified profile if the user name does exist. From within a profile, this command returns from the profile to system mode.
The user name displays in the prompt, following the router name.
The user name can be abbreviated to the fewest number of characters that make the name unique. The minimum is two characters. The maximum is 64 characters. User names are not case-sensitive. If no user name is specified, you return to system mode.
For authentication purposes, the user name is the string the remote device uses as a username when authenticating itself through Point-to-Point Protocol (PPP).
The following example moves from system mode (where the router name is Host) to a profile named 2503:
Host> cd 2503 Host:2503>
To display a list of commands and the syntax for each command, use the help command.
HElp [cmd [modifier]]
cmd | All commands for the specified group are listed. The most useful are set commands, reset commands, show commands, log commands, test commands, and unset commands. |
modifier | All modifiers for the specified command are listed. The most useful are ip (Internet Protocol), ipx (Internetwork Packet Exchange), and snmp (Simple Network Management Protocol). |
None
System or profile mode
Use this command to display online help information about commands. You can enter a question mark (?) in place of the word "help." Used without parameters, the command displays all the commands.
The following example displays help for the call command:
Host> help call CAll [ C# | L# | # | C#/L# | C#/# | #/# ] [ P# | CH# | P#/CH# ] [<number>] where C# indicates a Connection number # or L# indicates a Link number C#/L# or #/# indicates Link of a Connection P# indicates Port CH# indicates Channel P#/CH# indicates Channel of a Port <Q> and <enter> to Quit or <enter> for MORE
To implement the logging functions, use the log command.
LOg NOne | CAlls | MEssage | ERrors | IPx [TIme] [VErbose]
NOne | Disable all logging. |
CAlls | Log call statistics. Each major call event is logged, and a message displays every time a channel is assigned a connection. |
MEssage | Display a message when a channel is assigned a connection. |
ERrors | Log error messages that otherwise are not displayed, including buffer allocation errors, mail delivery errors, and chip-level errors. |
IPx | Display messages when Service Advertisement Protocol (SAP) entries get changed, interface characteristics are set or changed, or when erroneous Routing Information Protocol (RIP) information is received. |
TIme | Display time and date of each logged event or message. |
VErbose | Log all layers of the ISDN call control stack and traffic by printing the entire packet. |
LAN | Enable logging for the LAN connection. Used with packets or traffic. |
PAckets | Display statistics on packet routing once per second. Number of packets filtered, forwarded, received, and the packet queue lengths are displayed. |
TRaffic | Display a one-character indicator of each packet sent on the connection or the whole packet when verbose is specified. |
CHannel | Provide the channel number (logs traffic on a channel before the channel is assigned to a connection). This is primarily used to diagnose Point-to-Point Protocol (PPP) negotiation problems. |
INbound OUtbound | In conjunction with verbose, restrict the packet content display to either incoming or outgoing packets. |
Log calls
System or profile mode
The log command displays all enabled logged entries. More than one keyword can be entered at a time.
The following example shows output from the log calls command:
Host> log calls time cb760>ca16545 04/04/199600:24:08L0506545OutgoingCallInitiated cb760>cb760>01/01/199500:24:10L040LineDeactivated cb760>01/01/199500:24:10L270Disconnected cb760>

To determine whether a system can be reached on any connected interface, use the ping command.
PIng ipaddress
ipaddress |
None
System or profile mode
The router generates a ping packet that includes the source address of the profile from which it was sent. If the destination can be reached, the round-trip delay is determined and reported. If the destination cannot be reached, a "no response" message is generated.
The ping command automatically tries three times to reach the destination.
The following example illustrates a successful ping:
Host> ping 172.16.2.1 start sending : round trip time is 40 msec. start sending : round trip time is 40 msec. start sending : round trip time is 40 msec.
The following example illustrates an unsuccessful ping:
Host> ping 172.16.2.1 start sending : no response start sending : no response start sending : no response
To boot the router manually, use the reboot command.
REBootNone
System or profile mode
The following example shows a manual reboot:
Host> reboot Boot version 2.1(1) 08/13/97 17:33 Copyright (c) 1993-1997. All rights reserved. POST ............ OK (1.5MB). Validating FLASH ... OK.

To set accumulated packet counts to zero for one connection, use the reset packets command.
REset [connection | LAN] PACkets [ALl]
connection | |
LAN | Reset accumulated packet counts to zero on the LAN connection. |
ALl | Reset all accumulated packets. |
None
Profile mode
The following example resets the packet counts for profile 2503:
Host:2503> reset packets
show packets
To configure the baud rate for the console port, use the set baudrate command.
SEt BAudrate 300 | 1200 | 2400 | 4800 | 9600 | 19200 | 38400
300 | Configure the console port for 300 baud. |
1200 | Configure the console port for 1200 baud. |
2400 | Configure the console port for 2400 baud. |
4800 | Configure the console port for 4800 baud. |
9600 | Configure the console port for 9600 baud. |
19200 | Configure the console port for 19200 baud. |
38400 | Configure the console port for 38400 baud. |
9600 baud
System mode
The following example configures the console port for 2400 baud:
Host> set baudrate 2400
reboot
To place a limit on the length of time a data call is up, use the set callduration command.
SEt CALLDuration minutes
minutes | Maximum duration of a call in minutes. Enter any value between 1 and 1430. A value of 0 turns off any configured limit on data call duration. |
None
System or profile mode
The set callduration command is allowed only after system-level password authentication is complete.
This command does not affect voice calls.
The following example sets the duration of a data call to 10 minutes:
Host> set callduration 10
set calltime
set password
show callduration
To set the time of day when calls can be made or accepted, use the set calltime command.
SEt CALLTime [VOice | DAta] INcoming | OUTgoing [starttime | endtime]
VOice | Time-of-day parameters affect voice calls only. |
DAta | Time-of-day parameters affect data calls only. |
INcoming | Time-of-day parameters affect incoming calls only. |
OUTgoing | Time-of-day parameters affect outgoing calls only. |
starttime | |
endtime | Ending time of day when calls are no longer allowed. Enter the parameter in HH:MM format, where HH is a number from 0 to 23, and MM is a two-digit number from 00 to 59. |
OFf | Turn off any configured time-of-day limits on calls. |
None
System mode
The system time on the router must be set correctly for this feature to be accurate and effective. System-level password authentication is required before the set calltime command is allowed. The router does not have an auxiliary power supply, such as a battery, to maintain the router clock. If you power-cycle the router, reenter the system date and time.
The following example allows incoming voice calls from 8:00 am to 4:00 pm:
Host> set calltime voice incoming 08:00 16:00
set callduration
set date
set password
set sntp server
set time
show callduration
show calltime
To enable or disable data compression, use the set compression command.
SEt COmpression STac | OFf
STac | Enable data compression. |
OFf | Disable data compression. |
STac (enabled)
Profile mode
Turn compression off if you are using High Level Data Link Control (HDLC) protocol.
The following example disables compression for the profile 2503 connection:
Host:2503> set compression off
To set the current date, use the set date command.
SEt DAte MM/DD/YYYY
MM | A two-digit number from 01 to 12. |
DD | A two-digit number from 01 to 31. |
YYYY | A four-digit number from 1994 to 2020. |
The default date is 01/01/1995.
System mode
You must reset the date every time the router is booted. The date appears during logging.
The following example configures the date in the router for August 13, 1999:
Host> set date 08/13/1999
set time
To set all variable parameters to their default values, use the set default command.
SEt DEfaultNone
System or profile mode
The set default command resets all parameters to their default values, deletes the user-defined profiles, sets the Auto_Config flag to FALSE, and reboots the router. Setting the Auto_Config flag to FALSE triggers the auto-configuration procedure in the power-up operation.
The auto-configuration feature allows the router to obtain the configuration file from a remote server by using Bootstrap Protocol(BOOTP). Upon power-up, the router examines the Auto_Config flag stored in nonvolatile RAM (NVRAM). If the Auto_Config flag is FALSE, the router initiates a BOOTP to request an IP address from the server when a connection is established. (If the flag is TRUE, the BOOTP request is not initiated.)
When the router and BOOTP and TFTP servers at the central site are set up, use ping to generate traffic and trigger the ISDN call. When the call is connected, the Cisco 700 series router sends a BOOTP request. If the server finds a matching MAC address from BOOTPTAB, the server returns a client profile that includes an IP address and configuration filename. The router initiates a TFTP client request, requesting the server download the configuration file. (The U.S. image requires SPID and switch configuration information before the ISDN connection can be established.)
After successfully loading the configuration file, the router sets the Auto_Config flag to TRUE in NVRAM. In a subsequent power-up operation, if the Auto_Config flag is TRUE, the router does not initiate BOOTP to request a configuration file from the server.
This should be done on the LAN side (Ethernet interface) only. If this operation fails, the Auto_Config flag remains FALSE. If this is done on the WAN side and there is a WAN/PPP connection established, this process is triggered repeatedly on the WAN link.
The following example configures the router to default values:
Host> set default
reboot
To enable and disable terminal echo of keyboard entries, use the set echo command.
SEt ECho ON | OFf
ON | Enable terminal echo. |
OFf | Disable terminal echo. |
On
System mode
The following example disables terminal echo for the router:
Host> set echo off
To convert IPX packets to hexadecimal values for troubleshooting purposes, use the set ipx trace command.
SEt IPX TRace length | OFf | ON
length | Packet length (from 1 to 65535). |
ON | Enable IPX packet conversion to hexadecimal numbers. |
OFf | Disable IPX packet conversion to hexadecimal numbers. |
Off
Profile mode
The following example enables IPX trace and sets packet length to 4096:
Host> set ipx trace 4096 on
The following example disables IPX trace:
Host> set ipx trace off
To create a loop from the Cisco 700 series router toward the remote router on the ISDN line, use the set loopback command.
SEt [connection] LOOpback ON | OFf
connection | A connection number on which to create a loop. If no connection number is specified, a loop is created on the connection associated with the current profile. If the router cannot determine the connection number from the profile, the router displays an error message. |
ON | Enable a loop. |
OFf | Disable a loop. |
Disabled
System or profile mode
This command is used with the test command for troubleshooting purposes. In system mode, this command must be used with the connection-number argument. The router displays an error message if a connection number is not specified. In profile mode, the command uses the connection number for the profile. Use the show connection command to display which profiles have a loopback.
The following example creates a loopback on connection 1:
Host> set 1 loopback on
show connection
test
To set the maximum number of lines to display on the terminal, use the set screenlength command.
SEt SCreenlength lines
lines | Maximum screen length to display on your terminal. The length can be from 2 to 128 lines. |
20 lines
System mode
The following example configures the terminal to display 30 lines:
Host> set screenlength 30
set baudrate
set serialport
To toggle the serial port to function as a configuration port or a TPAD (Controller PAD) port, use the set serialport command.
SEt SErialport TPad | COnfig
TPAD | Set the serial port as a TPAD port. |
|---|---|
COnfig | Set the serial port as a configuration port. |
COnfig
System mode
When you enable the serial port as a TPAD, communications from a configuration terminal to the serial port are not possible. You can enter configuration commands by using Telnet. (Refer to the Cisco 700 Series Installation Guide for information on connecting a terminal to the router.)
To switch from TPAD mode to configuration mode, do one of the following:
Attention (AT) commands are entered at the prompt on the TPAD terminal.
There are two mode of operation in the TPAD implementation that respond to the enhanced point-of-sale system (EPOS), Verbose and Terse. In Verbose mode, the response is in strings, such as "CONNECT," "NO CARRIER," "BUSY" and so forth. In Terse mode the response is in numbers, such as 1 (CONNECT), 3 (DISCONNECT), 7 (BUSY), and so forth.
When the router is in TPAD mode, these responses are echoed to a terminal attached to the router serial port. Prior to software Release 4.3(1), the mode of operation was always verbose with echo on. In software Release 4.3(1), a series of TPAD commands were implemented to support RIVA functionality.
Multiple commands can be entered on a single line.
| Command | Description |
|---|---|
ATV0 | Response strings display in Terse mode (as numbers). |
ATV1 | Response strings display in Verbose mode (as strings). Default. |
ATE0 | Disable echoing commands. |
ATE1 | Enable echoing commands (default). |
ATP | Pulse dial prefix. |
ATDT | Tone dial prefix. |
AT&F | Force factory defaults. |
ATS7 |
The current state of the serial port can be displayed by using the show configuration command.
The following example sets the serial port as a TPAD port:
Host> set serialport tpad
set tpad parity
show configuration
show tpad
To configure the router name as the system prompt and for Point-to-Point Protocol (PPP) authentication, use the set systemname command.
SEt SYstemname [systemname]
systemname | Name used as the system prompt. |
No system name
System mode
The system name is case sensitive and can be from 1 to 64 characters. If no system name is entered, the system name is blanked.
The system name identifies the router when making PPP connections to an Internet service provider (ISP) if there is no PPP client name in the profile defined with the set ppp clientname command. If a PPP client name is defined in the profile, the router uses the PPP client name for PPP authentication; the router retains the system name as part of the prompt. To delete the system name, enter the systemname command without an argument.
The following example sets the system name to Host:
> set systemname Host Host>
set ppp clientname
To set the current time, use the set time command.
SEt TIme HH:MM:SS
HH | A two-digit number from 00 to 23. |
MM | A two-digit number from 00 to 59. |
SS | A two-digit number from 00 to 59. |
None
System mode
The time must be reset whenever the router is rebooted.
The following example configures the current time in the router:
Host> set time 08:48:20
set calltime
To select the communications parameters for TPAD, use the set tpad parity command.
SEt TPad PArity EVen | ODd | None
EVen | 7 data bits, 1 stop bit, and even parity. |
|---|---|
ODd | 7 data bits, 1 stop bit, and odd parity. |
None | 8 data bits, 1 stop bit, and no parity. |
None (8 data bits, 1 stop bit, and no parity)
System mode
You can change parity of TPAD communications in software Release 4.1(2) and higher. (In software Release 4.1(1), serial port communication is limited to 8 data bits, 1 stop bit, and no parity.)
The TPAD protocol requires the following X.25 fixed parameters:
The X.25 protocol requires the following fixed parameters:
X.28 and other X.25 Packet Assembly Disassemblies (PADs) are not supported because there is no provision for protocol sensing.
The call direction is dial-out only. Incoming calls and two-way calls are not supported.
Cisco 700 series router software Release 4.2(1) supports Network User Information (NUI) and Network User Address (NUA), as described in British Telecom CardWay 0800 Phase 3 Access Platform specification.
The following example sets the TPAD to even parity, 7 data bits, and 1 stop bit:
Host> set tpad parity even
set serialport
show tpad
To display the configuration and the status of both ISDN B channels, use the show command.

To download new router software or configuration files across a TCP/IP network using Trivial File Transfer Protocol (TFTP) or through the configuration port using a serial cable link, use the swl command.
SWL [TFTP] [CONFIG] [ipaddress filename]
TFTP | Load the software across a TCP/IP network by using TFTP or use the router as a TFTP server, depending on the status of the ipaddress and filename parameters. When the parameters are not included, the router is a TFTP (proxy) server. |
CONFIG | Load a configuration file across a TCP/IP network by using TFTP. |
ipaddress | |
filename | Name of the software image file when the router acts as a TFTP client during download. The filename should include the directory path if the file is not in the server default directory. When the filename is included, the ipaddress must also be included. |
None
System mode
The swl command assumes that communications occur through the configuration port. (See Cisco 700 Series Installation Guide for information on connecting a terminal to the router.)
The swl tftp command assumes that communications occur through a TFTP server.
The swl tftp command loads the software across a TCP/IP network by using TFTP when the ipaddress and filename are included. The command sets the router as a TFTP proxy server when an ipaddress and filename are not included. The software or configuration file must be stored on a client server. (TFTP server mode times out in 1 minute.)
On the TFTP client, you must use binary file transfer mode to transfer the software file. If the transfer is successful, the router reboots using the downloaded software and the downloaded configuration (if a configuration file was also downloaded). If the transfer was not successful, the router displays an error message or fails to boot, and the software must be reloaded.
The TFTP client and TFTP server implementation is based on RFC 1350. TFTP timeout interval and transfer size options are not implemented.
The following example loads the operating system software in the router through a serial connection from the terminal to the configuration port. (You can use an ASCII terminal or a personal computer running terminal emulation software.)
To load software with the swl command, follow these steps:
Step 1 Connect your terminal to the configuration port on the router.
Step 2 Set the baud rate for the terminal to 9600 and the protocol to 8N1.
Step 3 Turn on power to the router. The router boots, and when the boot process is complete, the router displays a prompt.
Step 4 Enter the swl command:
Host> swl
You are prompted to verify that you are downloading the software image.
Step 5 Enter y to continue:
Are you sure? y
You are prompted for the baud rate.
BOOT version 2.0(1) 04-16-96 12:03:06
Copyright (c) 1993-1996. All rights reserved.
Ready to upload new firmware into flash. Select baud rate:
1 - 300 baud
2 - 1200 baud
3 - 2400 baud
4 - 4800 baud
5 - 9600 baud
6 - 19200 baud
7 - 38400 baud
8 - 57600 baud
9 - 115200 baud
Step 6 At the prompt, enter one of the baud rates listed (do not press the Return key), and make sure that the load rate you choose is supported by your terminal emulation software. Table 2-6 shows the approximate software load times.
| Load Rate (Baud) | Approximate Time (Minutes) |
|---|---|
2400 | 48 |
9600 | 12 |
19200 | 6 |
38400 | 3 |
57600 | 2 |
115200 | 1 |
Step 7 Change the baud rate of the terminal to the appropriate download rate.
Step 8 Set the protocol to ASCII on the terminal.
Step 9 Download the file containing the new software to the router by following the prompts on your terminal. (The LINE LED blinks throughout the loading process.)
You are prompted to change the terminal baud rate to 9600.
Change settings to 8n1/9600 baud and press a key
Step 10 Change the baud rate of the terminal emulation software to the appropriate baud rate and press any key.
When the download is successful, the LINE LED turns off, and the RDY LED turns on. If the download was not successful, use Table 2-7, which shows symptoms and possible solutions.
| Symptom | Probable Cause and Solution |
|---|---|
Download takes significantly longer than the approximate time listed in Table 2-6. | The terminal emulation program interline and intercharacter delays are not set to zero. If the load was successful, no further action is necessary. If the load was terminated prematurely, reset the interline and intercharacter delays to zero, and reload the software. |
The terminal displays unrecognizable text after the download is completed. | The terminal has not been reset to 9600 baud. Reset the terminal any time after loading the new software. After changing the terminal baud rate, press Return to gain access to the standard prompt (>). |
Two or more LEDs are blinking. | Incorrect configuration of the PC COM port or a defective console cable. Press Esc on the keyboard, and try to load the software again. |
The following example shows the transfer of an image by using TFTP. The router is the server and the workstation is the client. (Before beginning this procedure, configure your workstation to operate as a TFTP client. In server mode, the workstation only accepts put requests for the file.
Step 1 Check the file directory to confirm that the new software and, optionally, the new configuration file are installed on the TFTP server.
Step 2 Ping the TFTP server from the router to confirm that the router can be reached from the client machine:
Host> ping clientipaddress
 | Caution When the swl tftp command is entered, the existing software is erased. If a catastrophic event such as a power failure occurs before the file transfer is complete, the router must be initialized through the configuration port. |
Step 3 Enter the swl tftp command to load the software image on the router:
Host> swl tftp 171.69.91.33 foxus.fl Are you sure? y Host> SWL TFTP: Starting transfer ... SWL TFTP: Transfer successful. Image received successfully. Burning flash, standby (15 seconds max.) ...
The software is downloaded. You can follow the same procedure using the swl tftp config command to download a configuration:
Host> swl tftp config 171.69.91.33 efoxcfg.txt Are you sure? y Host> SWL TFTP: Starting transfer ... SWL TFTP: Transfer successful. SWL TFTP: Erasing old configuration. Host> Connection 1 Closed Host> Connection 2 Closed Host> Connection 3 Closed Host> Connection 4 Closed Host> SWL TFTP: Setting new configuration.
Step 1 From the terminal emulation program, go to the Setting menu, and select Text Transfer. The Text Transfer dialog box appears.
Step 2 Set flow control to Line at a Time, and set Delay Between Lines to 0.5 to 1 second.
Step 3 Click OK.
Step 4 From the Transfer menu, select Send Text File.
Step 5 Select the file to be loaded.
Step 6 Click OK. The parameters are transferred to your router.
Step 7 If errors occur during the transfer, enter the set default command, increase the delay between lines, and repeat the procedure for loading the configuration beginning with Step 1.

To generate test packets, use the test command.
TEst [connection] [WAn | ALl] [STop | REsult | ETher] RAte pps [MInpkts bytes MAxpkts bytes]
connection | Number of the connections where test packets are generated. |
WAn | Generate test packets on the (WAN) ISDN line. Packets should be sent to a WAN switch that has a loopback enabled. Compare number of sent packets to number of received packets. |
ALl | Generate test packets on both the ISDN line and on the LAN. |
STop | Stop all test packets from being generated. |
REsult | Display results of last completed test. |
ETher | Generate test packets on the LAN and compare the number of sent packets to the number of received packets. |
RAte | Rate in packets per second (pps) at which test packets are generated. The rate can be between 1 and 100; the default value is 10. |
MInpkts | Minimum size (in bytes) of test packets. The size can be between 60 and 1514; the default value is 60. Packets are generated in incrementally larger sizes, starting with the minimum size and ending with the maximum size. After the maximum length is reached, the next packet is the minimum size. |
MAxpkts | Maximum size in bytes of test packets. The size can be between 60 and 1514; the default value is 1514. |
None
System mode
The following example enables a test on the ISDN line and the LAN with a minimum packet size of 255 bytes and a maximum packet size of 1024 bytes:
Host> test all min 255 max 1024
To send a set of ASCII strings containing the current configuration to the terminal or TFTP client, use the upload command.
UPload [TFTP ipaddress filename]
TFTP | Upload the configuration across a TCP/IP network by using TFTP. The output goes to the console port if this parameter is not included. |
ipaddress | TFTP server IP address. |
filename | Name of the file where the router configuration is to be stored on the TFTP server. The filename field should include the directory path if the file is not in the default directory of the server. |
None
Profile mode
The upload command (without any parameters) sends the current configuration to the console port. The upload tftp command uploads the configuration through a TFTP client.
You can use the captured file to reconfigure the router after loading new software or to configure multiple routers with the same parameters.
Set the ASCII download for 1 second so that each line is correctly processed.
The following example uses TFTP to send the router configuration to IP address 10.1.1.1, filename 700ted.cfg:
Host> upload tftp 10.1.1.1 700ted.cfg
set default
set echo
swl
To display the software release level and date, use the version command.
