Caution The following formatting procedure erases all information in the Flash memory. To prevent the loss of important data, proceed carefully. |
Syntax Description
device1: Device to format. The colon (:) is required. Valid devices are as follows: device2: Device containing the monlib file to use for formatting device1. The colon (:) is required. Valid devices are as follows: 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.
Defaults

11.1(4) New command
Release
Modification
Usage Guidelines
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.
Examples
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.

Usage Guidelines
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 increases the available bit rates for the Frame Relay PVC and soft VC but does 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 the CIR overbooking factor is configured.

The cttr should be configured before using the atm pvc command. Refer to the atm connection-traffic-table-row command for information on configuring the tx-cttr. pd {on | off} Specifies the intelligent packet discard option as on or off. The default is off. retry-interval Configures retry interval timers for a soft PVC. first retry-interval Retry interval for the first retry after the first failed attempt, specified in milliseconds. If the first retry after the first failed attempt also fails, the subsequent attempts are made at intervals computed using the first retry-interval, as follows: (2 ** (k-1)) * first retry-interval Where the value of k is 1 for the first retry after the first failed attempt and is incremented by 1 for every subsequent attempt. Range is from 100 to 3600000 milliseconds; the default is 5000 milliseconds. maximum The maximum retry interval between any two attempts, specified in seconds. Once the retry interval is computed in the first retry-interval and becomes equal to or greater than the maximum retry-interval configured, the subsequent retries are done at regular intervals of maximum retry-interval seconds until the call is established. Range is from 1 to 65535 seconds; the default is 60. network [clp-bit Specifies the interworking function, which can be either network or service interworking. For soft PVCs that originate from a Frame Relay interface and end on a Frame Relay interface, the default is network interworking. For soft PVCs that originate from a Frame Relay interface and end on an ATM interface, the default is service interworking. clp-bit Sets the mode of DE/CLP mapping in the Frame Relay to ATM direction. Values 0, 1, or map-de are allowed for both network interworking and service interworking. The default is map-de. de-bit Sets the mode of DE/CLP mapping in ATM to Frame Relay direction. [network | service Specifies the interworking function, which can be either network interworking or service interworking in transparent mode, or service interworking in translation mode. efci-bit For service interworking only. Sets the mode of FECN/EFCI mapping in the Frame Relay-to-ATM direction. The default value is 0. Values 0 or map-fecn are allowed. enable Enables the soft connection, and allows it to be set up. This is the default for the initial soft connection configuration. However, if the frame-relay soft-vc command is reentered for an existing connection, the default is to remain in the current enabled or disabled state. disable Disables the soft connection, which prevents it from being set up initially, or tears down an existing connection. explicit-path The PNNI explicit path that is manually configured for routing a soft PVC, using the atm pnni explicit-path command. precedence The precedence number by which ATM PNNI explicit paths are assigned, from 1 to 3. Up to three explicit paths can be assigned to a name path-name The name of the ATM PNNI explicit path for routing soft PVCs. identifier path-id The name of the ATM PNNI explicit path for routing soft PVCs. upto Allows a subset of a longer explicit path to be used, so that all included nodes after the specified entry-index are disregarded. If the destination is reachable at any next node or segment target, the remaining included nodes in the explicit path are disregarded automatically. only-explicit If one or more explicit paths have been specified and the explicit path fails, the soft connection remains down until it is retried at its next retry interval. If this option is not specified, the system uses the standard on-demand routing instead of waiting for the next retry interval. redo-explicit Applies only to existing soft connections and allows explicit paths to be respecified without tearing down connections. Existing connections are unaffected unless a reroute takes place, and then they use the newer explicit-path configuration.

Usage Guidelines
Obtain the destination port address before configuring a soft PVC by using the show atm interface or show atm addresses command on the destination switch.
The following list identifies reasons why the creation of a soft PVC is unsuccessful:
Up to three explicit paths can be assigned to a soft VC, using precedence numbers 1 through 3. The precedence 1 explicit path is considered the primary path and is tried first. If it fails, then the next precedence path is tried. Explicit paths can be specified either by name or by identifier.
The explicit-path options can be changed without tearing down an existing Frame Relay soft PVC. Use the redo-explicit form of the command to respecify all of the explicit-path options.
After configuring a Frame Relay soft PVC, use the show vc command on the source node (specifying the serial interface and DLCI) to verify that the soft PVC has succeeded and to see the explicit path taken.

Examples
The following example shows how to create a soft PVC between two Frame Relay connections.
Switch# configure terminal Switch(config-if)# frame-relay soft-vc 50 dest-address 47.0091.8100.0000.00e0.1e79.8803.4000.0c81.8020.00 dlci 50 upc pass
The following example shows how to create a soft PVC between a Frame Relay connection and an ATM connection.
Switch# configure terminal Switch(config-if)# frame-relay soft-vc 60 dest-address 47.0091.8100.0000.0060.3e5b.7201.4000.0c80.8000.00 vc 0 100
The following example shows these connections via the show vc command.
Switch# show vc interface serial3/0/0:1 Interface Conn-Id Type X-Interface X-Conn-Id Encap Status Serial3/0/0:1 50 SoftVC Serial3/0/0:2 50 UP Serial3/0/0:1 55 PVC Serial3/0/0:2 55 UP Serial3/0/0:1 60 SoftVC ATM1/1/1 0/35 UP Serial3/0/0:1 66 PVC Serial3/0/0:2 66 UP
In the show vc example above, the Frame Relay-to-Frame Relay connection originates from Serial 3/0/0:1 and terminates at Serial 3/0/0:2. The Frame Relay-to-ATM connection originates from Serial 3/0/0:1 and goes out through ATM 1/1/1 and ends on an ATM interface on an adjacent switch.
The following example shows how to manually configure an explicit path between two Frame Relay connections. In this example, if the explicit path fails, standard routing is used.
Switch# configure terminal Switch(config)# interface atm 0/1/3 Switch(config-if)# frame-relay soft-vc 100 dest-address 47.0091.8100.0000.1061.705b.d900.4000.0c81.9000.00 dlci 100 explicit-path 1 name chicago.path1
The following example shows how to use the redo-explicit keyword to modify an existing explicit-path configuration to add a second alternate explicit path and to prevent standard routing from being used should both explicit paths fail. Note that the system prompts you to confirm the changes.
Switch(config)# interface atm 0/1/3 Switch(config-if)# frame-relay soft-vc 100 redo-explicit explicit-path 1 name chicago.path1 explicit-path 2 name chicago.path2 only-explicit Modify with new explicit path options [yes], or abort changes [no]? [yes/no]:y
The following example shows how to remove all explicit paths from an existing Frame Relay soft PVC by using the redo-explicit keyword, with no other options specified. The path will not be changed until a reroute occurs.
Switch(config)# interface atm 0/1/3 Switch(config-if)# frame-relay soft-vc 100 redo-explicit Modify with new explicit path options [yes], or abort changes [no]? [yes/no]:y
