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 route processor card. · slot1: This device is the second PCMCIA slot on the route processor card. |
device2: | 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 route processor card. |
monlib-filename | 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 route processor card.
Switch# format slot0:
Running config file on this device, proceed? [confirm]y
All sectors will be erased, proceed? [confirm]y
Enter 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.

When you create a connection traffic table row, the Frame Relay parameters are converted into the ATM equivalent parameters and a row is added into the ATM connection traffic table. The table index values are shared by the Frame Relay connection table and the ATM connection table. If you specify the index in the command, the index value is available in the ATM connection table. As a result of the index value being linked to the ATM connection traffic table, the index values in the Frame Relay connection traffic table might not be contiguous.
The following example shows how to create a table entry with a row index of 150, committed information rate of 1024000, committed burst size of 16334, peak information rate of 1024000, excess burst size of 20, and the abr service category with an ATM row index 250.

frame-relay lmi-n393dce events
events | Monitored events count value. The value must be a positive integer from 1 to 10. |
2 events
Interface configuration
This command and the frame-relay lmi-n392dce command define the condition that causes the link to be down. In the Cisco implementation, N392 errors must occur within the events count for the link to be down. Therefore, the events value that you define for this command must be greater than the threshold value defined in the frame-relay lmi-n392dce command.
The following example shows how to set the LMI monitored event count to 3.
Switch(config)# interface serial 11/0/0:1

To configure discard marking thresholds on a Frame Relay interface in the output direction, use the frame-relay output-queue interface configuration command. Use the no form of the command to revert to default values for the threshold.
frame-relay output-queue {abr | ubr | vbr-nrt} {discard-threshold | marking-threshold} threshold percentage
abr | ubr | vbr-nrt | Service categories for which the threshold is configured. |
discard-threshold | Threshold where the cell is discarded. If the queue fills above this level, any frame arriving from the switch with DE bit set will be discarded by the interface. Default is 87 percent. |
marking-threshold | Threshold where the cell is marked for EFCI. If the queue fills above this level, all frames arriving from the switch will have the FECN bit set in the frame header as they exit the interface. For cells entering the Frame Relay interface from an external device, the BECN bit will be set in the frame header as it enters the switch. Default is 75 percent. |
threshold_percentage | Percentage number. |

To set the percentage of overbooking of committed information rate (CIR), use the frame-relay overbooking command. To disable CIR overbooking, use the no form of this command.
frame-relay overbooking percent
percent | The percent of interface bandwidth from 101 to 1000. |
Disabled
Interface configuration
The allowable overbooking on an access link or interface is a number times the access link or interface speed (access rate). For example, 200 percent of the access rate. The total of all CIRs for all Frame Relay PVCs and Frame Relay soft VCs cannot exceed the CIR overbooking factor times the access rate.
Once configured and used to admit Frame Relay PVCs and Frame Relay soft-VCs on an interface, the CIR overbooking factor can only be adjusted within the upper limit and the level which has been overbooked by the existing connections. Disabling the CIR overbooking factor is allowed only when the total of all CIRs for all Frame Relay PVCs and Frame Relay soft VCs does not exceed the interface access rate.
Configuring the CIR overbooking factor will increase the available bit rates for the Frame Relay PVC and soft-VC but it will not increase the actual bandwidth (access rate) and resources available to the Frame Relay interface.
The CIR of a connection is not allowed to exceed the actual access rate of an interface even if CIR overbooking factor is configured.
You should have a thorough understanding of network traffic patterns when using the frame relay overbooking command. Excess traffic arriving at an overbooked Frame Relay interface may lead to discarded or discard eligible (DE) tagged frames.
The following example configures the Frame Relay serial interface to allow overbooking the CIR to 200 percent.
Switch(config)# interface serial 1/1/0:5
Switch(config-if)# encapsulation frame-relay ietf
Switch(config-if)# frame-relay overbooking 200

Because soft-VCs are created over ATM networks, the destination address is an ATM address plus either DLCI if the remote end is a Frame Relay interface, or VPI/VCI if it is an ATM interface.
Like Frame Relay to Frame Relay PVC, Frame Relay to Frame Relay soft-VC uses network interworking with FECN mapping, DE-BIT mapping, and CLP-BIT mapping.
The following example configures a Frame Relay soft VC 500 on serial interface 11/0/0:1 to Frame Relay NSAP address 47.0091..., DLCI 150.

Use the framing controller configuration command to specify the type of framing used by the channelized E1 interface If you do not specify the framing type, the default crc4 is used by 4CE1 Frame Relay port adapter.
The following example shows how to set the framing for the Frame Relay E1 port adapter to no-CRC4.
Switch(config)# controller e1 11/0/0
Switch(config-controlle)# framing no-crc4
show controller e1
Use the framing controller interface configuration command to select the frame type for the data line.
framing framingmode
framingmode | For DS3, framingmode is as follows: m23adm | m23plcp | cbitadm | cbitplcp For E3, framingmode is as follows: g832adm | g751adm | g751plcp For E1, framingmode is as follows: crc4adm | crc4plcp | pcm30adm | pcm30plcp For T1, framingmode is as follows: esfplcp | sfplcp | sfadmn | esfadmn |
DS3 default is cbitplcp.
E3 default is g832adm.
E1 default is crc4plcp.
T1 default is esfplcp.
Interface configuration
In the DS3 environment, this subcommand allows selection of DS3 framing mode to M23 ADM, M23 PLCP, C-Bit ADM, or C-Bit PLCP.
In the E3 environment, this subcommand allows selection of E 3 framing mode to G.751 PLCP, G.751 ADM, or G.832 ADM.
The following example shows how to select g751plcp as the frame type.
Switch(config-if)# framing g751plcp
