A workaround would be to arrange with Operations to hard mount a tape and then reference the unit in the SITE command. This means that Operations should not terminate the mount request by cancelling the job requesting the mount. A reply of NO to this message cancels the request.

FTP will timeout a data transfer request if the remote does not complete the data connection in a certain time. If the remote is another MVS system using tapes or recalling a data set it will require a tape mount on the remote system before it can complete the data connection. If a remote is reading a multivolume , for example, it might have to stop the data transfer between volumes while the next tape is mounted.

Not all of the commands listed in are documented in this publication. The others in this list conform to their descriptions in RFC The supported FTP commands are described in detail throughout the remainder of this chapter. A comma can replace R. These are the allowable variations of the ALLO command syntax:. Once an ALLO R value has been set, a file received with a record longer than this limit is truncated rather than folded.

Output from the HELP command is delivered to you by the control connection; the output can be terminated by the Telnet Break facilities.

Read Telnet Break. When no option is specified, general help information is given. Title of a reference source of introductory or reference information provided through the control connection. AC or EC. AN or EN. STRU R. The REST restart command specifies that the data transfer command that follows immediately is to restart at a specified intermediate point in the file.

A file retrieved from the Server FTP includes restart markers at a specific interval. When the count of bytes read from the disk since the last marker reaches the specified interval, a marker is sent at the next end of a complete logical record or segment of a spanned record.

V olume sequence number. A byte offset within a TTR block. It will not delete a PDS that contains members. SITE parameter [ , ] Specifies any entry in the Generic Attributes table. Read Generic Attribute Names for details.

Requests that the data set sequence number be increased by one for each subsequent file transfer. If the data set exists, these parameters must exactly match the corresponding attributes of the data set.

NOCD disables directory commands. This table is validated for single-byte data. Specifies IDRC compaction for tapes. Each data set is listed individually. This table will be validated for double-byte data. Specifies the time, in seconds, FTP will wait on an idle data port. DIR blocks. Integer number of byte blocks to be reserved for a PDS directory. One block holds from 7 load module to 16 source module member entries.

Data sets which have the same qualifier at the level immediately below the prefix level are grouped together as "pseudo-directories". Note yyyy is a year from to , ddd is a julian date from 1 to You must include any leading zeroes in the ddd value. SEQ —Sequential files. Data is written to the JES internal reader.

Default: SEQ. IBUF numbuf bufsize. Specifies in sublist notation the number of network input buffers numbuf and the buffer size bufsize to be used during data transfer. The maximum value for each number is This assures data integrity while the PDS you are accessing is being simultaneously accessed by the linkage editor from another system. The short format leaves out data set extents and tracks allocated, but improves LIST response time. The LIST parameter is not reset when data transfer begins.

Specifies the SMS management class. MOUNT time. Enables tape support ability for this file transfer. The time value specifies the maximum wait time in minutes for the tape mount to complete.

If the time expires, the request is aborted. MOUNT without a time value specified will use the default system wait time. Alias of NDAB. NDAB number1 number2. The maximum value is Specifies whether the output from an NLST command will be upper- or lowercase. If LOWER is specified and the data set or member list is part of the current directory, the names will be returned in lowercase. Note This parameter is not reset when data transfer begins. OBUF numbuf bufsize.

Specifies, in sublist notation, the number of network input buffers numbuf and the buffer size bufsize to be used during data transfer. This parameter is a toggle. The defaults are blanks for character types and zeros for binary types. These are the pad-codes:. Specifies parallel mounting mutually exclusive with UCNT. Specifies whether SITE parameters will be reset following data transfer. Each PUSH adds an entry to a push-down stack. Each POP pulls the last entry from the stack.

When there are no entries in the stack, a POP will result in an error reply. The integer value specifies the maximum wait time in minutes for HSM to complete the recall of the migrated file. Resets all previous SITE commands. This is needed occasionally to prevent building up too many extents when many APPE operations to the same data set are performed.

Specifies primary and secondary disk space allocation the default allocation is in tracks. Specifies the SMS storage class. Specifies whether pad characters will be stripped from fixed-length logical records when data is retrieved using RETR.

TABS integer. Writing startup-config It is the only needed file if you want to manage switches or cluster of switches through a web interface. Issue the show flash: command mentioned above to verify the amount of free memory — it must be sufficient to upgrade. Switch archive download-sw?

There are number of options, but in this particular case we are interested in upgrade the IOS via FTP, so we need to create an username and password by using the ip ftp username [username] and ip ftp password [password].

Installation will be done as many times as there are switches in the stack. Using show boot command, you can verify if the new image is now the image in the BOOT path-list that will load at the next switch reload. Use the reload command at the prompt and confirm to begin reloading. In the example, we explicitly configured a FTP username and password on the router.

You can also override the username and password settings defined in the configuration file by including them on the command line:. Notice that we used URL format to specify the username and password as well as the server address and the filename that we wanted to download.

A colon separates the username, ijbrown , from the password, ianpassword. An sign then separates the user information from the server information, which can be either an IP address or a DNS name. Final completion of the data transfer command is indicated with a message.

In many cases, if the optional parameters are omitted from the command line, you are prompted for them. Because the Client FTP program implements the three-party model in which the Client FTP program establishes control connections to two Server FTPs, you need a way to identify which connection is to be used for certain commands. A host prefix is one of the A: or B: character strings. The A? B command shows the host name associated with each host prefix in case you become confused.

Client FTP command host prefixes can be required, not allowed, ignored, or optional. If you give a prefix, the command applies only to that specific host.

If you omit the prefix, the command applies to both hosts, provided the connection to the host is open. The exception is the CONN command. If a prefix is omitted, the first available, unused host prefix is assigned to the connection. This section describes the Client FTP commands. The remainder of this chapter provides detailed descriptions of the commands. Terminate program same as QUIT. Copy file from remote host to local host same as RECV. Copy file from local host to remote host same as SEND.

Terminate program same as BYE. Copy file from local host to remote host same as PUT. Re-send last SITE command to local host. Each command name is preceded by a special character that indicates the requirement for host prefixing for that particular command. A key is provided in the display to explain the prefix requirement indicated by each special character. If a command name is specified as an argument on the? The following example shows a request for information about using the log command.

Requests help from a server FTP program. By contrast, the? No action is taken by the Server FTP if the previous command has been completed including data transfer. The control connection to the Server FTP is not closed, but the data connection is closed.

A host prefix is optional with the ABOR command. The file retrieved is always at host A and the target file is always at host B. Refer to the documentation for your particular Server FTP to see if you need this command. ALLO integer1 [ R integer2 ]. For files sent with record or page structure, a maximum record or page size in logical bytes can be required. This is indicated by the second integer argument. The integer2 argument is optional, but if it is specified, it must be separated from the first by the three characters, " R " space R space.

CONN [ hostname ]. Provides the host name to which one FTP control connection is established. If you omit the host name, you are prompted to provide one. If the host prefix is omitted, the first available unused host prefix is assigned to that connection.

Host name strings must correspond to the syntax specified in Using Host Name Strings in. A host prefix is optional with the CONN command. If a host prefix is specified, the connection is assigned to that host prefix. Indicates to the Server FTP the name of the directory to be made the current directory. This is typically the last command you enter. Any open control connections are closed before the program terminates. The EXPE command toggles the use of experimental or regular directory commands.

Since there is no consistent support for this command, it is recommended that you not use this command. The file to be retrieved is always at host B, and the file to be copied to is always at host A. HELP [ text ]. If no host prefix is given, help is requested from each host with an open control connection. Different Server FTPs may interpret these operands differently. A host prefix is optional with the HELP command.

If a host prefix is specified, help information is requested only from that host. This contrasts to the NLST command that provides only a list of file names without any other file information. If the path name specifies a directory or other group of files, the Server FTP transfers current information for a list of files.

If the path name specifies a single file, the Server FTP transfers current information on that file. The new password replaces the current password after the user ID and current password are validated. The new password must follow the slash without any intervening blanks. If the Server FTP requires additional accounting information during the user identification process, the Client FTP program prompts you to enter the accounting data.

If the path name is relative, the specified subdirectory is created in the current working directory. Stream mode passes the data with little or no processing. It interacts with the structure attribute to determine the type of processing. Stream mode is the default if no MODE command was used. The sending host translates its internal end-of-line or end-of-record representation into the representation required by the transfer mode and file structure; the receiving host performs the inverse translation to its internal representation.

Because these transformations make extra work for some systems, identical systems transferring non-record structured text files might use binary representation and stream mode to simplify transfer. One of the three codes is required as an argument on the MODE command. A host prefix is optional with the MODE command. Each of the possible transmission modes is discussed in the following sections. Not all Server FTPs support all transmission modes; review the documentation for the target Server FTP if you have questions concerning transmission mode support.

In this instance, compress mode is valid if both remote servers support compress mode. Set block mode with the character B. In block mode, the file is transmitted as a series of data blocks preceded by one or more header bytes. Record structures are allowed in this mode, and any representation type can be used. Restart markers are embedded in the data stream. Set compressed mode with the character C.
