TFTP Manage 0x003A

SwitchKit Name

TFTPManage

Type

EXS API and SwitchKit API message

Description

This message is used to download system software files and to query the TFTP configuration. You can send this message no matter what state the Matrix Controller card is in.

To download Excel platform software, send the Begin Download ICB as well as appropriate Data ICB subtypes to send the following information to the Excel platform:

Local Matrix Configuration Filename

Adjacent Matrix Configuration Filename

Local Matrix Server IP Address

Adjacent Matrix Server IP Address

Load Timestamp

Send the Begin Download ICB whenever you assign a new TFTP configuration file that contains information about a new load.

To query the TFTP configuration, send one of the Action ICB query subtypes. The response to a query includes the corresponding Data ICB subtype.

The Timestamp ICB is required only if the timestamp is not in the configuration file.

Save Options, Load Version & Load Filename are Excel platform-initiated ICBs in response to the Query ICBs.

Adjacent Matrix ICBs are needed only if you have an adjacent matrix, but they can also be sent directly to the adjacent matrix, instead of through the local matrix.

Status MSB (0x00)

 

Status LSB:

0x00 No Timestamp Available

A timestamp has not been supplied
in either the TFTP Manage
message or the TFTP
Configuration file.

 

0x01 Two Timestamps

The TFTP Manage API message
and the TFTP Configuration file
both contain a timestamp.

 

0x02 Old Timestamp

The supplied timestamp is older
than the adjacent Matrix Controller
load’s timestamp, therefore; the
load will be overwritten.

 

0x03 Timestamp is Equal

The supplied timestamp is equal to
the adjacent Matrix Controller
load’s timestamp, therefore the
cards might have different loads.

 

0x04 Incorrect ICB Type

The incorrect ICB Type is indicated
in the More Status field.

0x05 Incorrect ICB Subtype

The incorrect ICB Subtype is indicated in the More Status field.

 

0x06 Incorrect ICB Length

Fixed length ICB has wrong length or variable length (filename) ICB has a zero length.
The ICB Subtype with the incorrect length is indicated in the More Status field.

 

 

0x07 Invalid Message Length

Overall message length is less than minimum or aborts ICB in the middle.
The supplied length is indicated in the More Status field.

 

0x08 TFTP of Configuration File Failed

The failure reason is indicated in the More Status field.

 

0x09 TFTP Load Validation Failed

The Failure Reason is indicated in the More Status field.
See Response Status 0x08 (TFTP of Configuration File Failed) for Failure Reason values.

 

0x0A Load is From Wrong Release

New load information is for a different load than the Excel platform is running.
The supplied load number is indicated in the More Status field.

 

0x0B Filename is greater than 127 characters.

The length supplied length is indicated in the More Status field.

 

0x0C Unknown Load Number

The host-supplied load number is greater than maximum known loads.
The supplied load number is indicated in the More Status field.

 

0x0D Response Would Be Too Long

The message response would be greater than 256 bytes.
There are too many queries in the message.

 

0x0E Configuration File Changes Save Option Without Begin Download ICB

A new TFTP Configuration filename is not compatible with the current load configuration.
The failing load number is indicated in the More Status field.
