To set the method of data flow control between the terminal or other serial device and the switch, use the flowcontrol line configuration command. To disable flow control, use the no form of this command.
flowcontrol {none | software [in | out] | hardware [in | out]}| none | Turns off flow control. |
| software | Sets software flow control. An optional keyword specifies the direction: in causes the switch to listen to flow control from the attached device, and out causes the switch to send flow control information to the attached device. If you do not specify a direction, both are assumed. |
| hardware | Sets hardware flow control. An optional keyword specifies the direction: in causes the switch to listen to flow control from the attached device, and out causes the switch to send flow control information to the attached device. If you do not specify a direction, both are assumed. |
Flow control is disabled.
Line configuration.
This command pertains to the auxiliary port only.
When software flow control is set, the default stop and start characters are ^S and ^Q (XOFF and XON). You can change them with the stop-character and start-character commands.
The following example sets hardware flow control on the auxiliary port.
Switch(config)#line aux 0Switch(config-line)#flowcontrol hardware
To format Flash memory, use the format privileged EXEC command.
format device1: [[device2:][monlib-filename]] | Caution The following formatting procedure erases all information in the Flash memory. To prevent the loss of important data, proceed carefully. |
| device1: | Device to format. The colon (:) is required. Valid devices are as follows:
· bootflash: This device is the internal Flash memory. · slot0: This device is the first PCMCIA slot on the ASP card. · slot1: This device is the second PCMCIA slot on the ASP card. |
| device2: | (Optional) Device containing the monlib file to use for formatting device1. The colon (:) is required. Valid devices are as follows:
· bootflash: This device is the internal Flash memory. · slot0: This device is the first PCMCIA slot and is the initial default device. · slot1: This device is the second PCMCIA slot on the ASP card. |
| monlib-filename | (Optional) Name of the ROM monitor library file (monlib file) to use for formatting device1. The default monlib file is the one bundled with the system software. |
The default monlib file is the one bundled with the system software.
Privileged EXEC.
Use the format command to format internal Flash memory (bootflash) or your Flash memory cards.
In some cases, you might need to insert a new PCMCIA Flash memory card and load images or backup configuration files onto it. Before you can use a new Flash memory card, you must format it.
Flash memory cards have sectors that can fail. You can reserve certain Flash memory sectors as "spares" for use when other sectors fail. Use the format command to specify between 0 and 16 sectors as spares. If you reserve a small number of spare sectors for emergencies, you do not waste space because you can use most of the Flash memory card. If you specify zero spare sectors and some sectors fail, you must reformat the Flash memory card and thereby erase all existing data.
The monlib file is the ROM monitor library. The ROM monitor uses the monlib file to access files in the Flash file system.
In the command syntax, device1 is the device to format, and device2 contains the monlib file to use. When you omit the [[device2:][monlib-filename]] argument, the system formats device1 using the monlib file that is bundled with the system software. When you omit device2 from the [[device2:][monlib-filename]] argument, the system formats device1 using the named monlib file from the device specified by the cd command. When you omit monlib-filename from the [[device2:][monlib-filename]] argument, the system formats device1 using device2's monlib file. When you specify the whole [[device2:][monlib-filename]] argument, the system formats device1 using the specified monlib file from the specified device. Note that you can specify device1's own monlib file in this argument. When the system cannot find a monlib file, the system terminates the formatting process.
The following example shows the format command that formats a Flash memory card inserted in slot 0 of the ASP card.
Switch#format slot0:Running config file on this device, proceed? [confirm]yAll sectors will be erased, proceed? [confirm]yEnter volume id (up to 31 characters): <Return> Formatting sector 1 (erasing) Format device slot0 completed
When the switch returns you to the EXEC prompt, the new Flash memory card is successfully formatted and ready for use.

To select the frame type for the data line, use the framing controller interface configuration command.
framing framingmode| framingmode | For DS3, framingmode is as follows:
m23adm | m23plcp | cbitadm | cbitplcp For E3, framingmode is as follows: g832adm | g751adm | g751plcp |
cbitplcp for DS3 and g832adm for E3.
Interface configuration.
In the DS3 environment, this subcommand allows selection of DS3 framing mode to either M23 ADM, M23 PLCP, C-Bit ADM, or C-Bit PLCP.
In the E3 environment, this subcommand allows selection of E3 framing mode to either G.751 PLCP, G.751 ADM, or G.832 ADM.
The following example selects g751plcp frame as the frame type.
Switch(config-if)# framing g751plcp
To get help for the full set of user-level commands for the unprivileged user, use the full-help command.
full-helpThis command has no arguments or keywords.
All.
The full-help command enables a user dialing into a line without privileged access to see all of the help messages available. The full-help system is accessed by entering the command argument and a space followed by a question mark.
The following example shows the command for enabling access to all of the help messages available.
Switch(config-line)# full-help
