35.1. TFTP - Trivial File Transfer Protocol

The TFTP has been introduced to bootstrap certain ip phones models.

35.1.1. Activating the TFTP resource

Add the resource to the Abilis system with the following command.

[09:08:14] ABILIS_CPX:a res:tftp

RES:TFTP ALREADY EXISTS

The TFTP resource may already exist in the system, but may not yet be active: set it active with the following command.

[09:10:00] ABILIS_CPX:s act res:tftp

COMMAND EXECUTED
[Caution]Caution

You must restart the Abilis to make the resource running (use the command warm start to reboot the Abilis) after adding or setting the TFTP active.

[13:07:41] ABILIS_CPX:d p tftp

RES:Tftp ----------------------------------------------------------------------
Run    DESCR:Trivial_File_Transfer_protocol
       LOG:NO        ACT:NO    udp-locport:69   srv-sess:10   TOS:0-N
       RTY:5         TOUT:3    WRITE-PERMISSIONS:NO
       IPSRC:127.000.000.001   IPSRCLIST:PrivateIpAdd
       WDIR:C:\APP\TFTP\
[Caution]Caution

Execute the initialization command init res:tftp to activate the changes made on the upper case parameters; use save conf and warm start commands to set active the changes made on the lowercase parameters.

[10:50:25] ABILIS_CPX:s p tftp act:yes

COMMAND EXECUTED

[10:51:33] ABILIS_CPX:d p tftp

RES:Tftp - Not Saved (SAVE CONF), Not Refreshed (INIT) ------------------------
Run    DESCR:Trivial_File_Transfer_protocol
       LOG:NO        ACT:YES   udp-locport:69   srv-sess:10   TOS:0-N
       RTY:5         TOUT:3    WRITE-PERMISSIONS:NO
       IPSRC:127.000.000.001   IPSRCLIST:PrivateIpAdd
       WDIR:C:\APP\TFTP\

[10:51:41] ABILIS_CPX:save conf

VALIDATION IN PROGRESS ...
VALIDATION SUCCESSFULLY EXECUTED

SAVE EXECUTED

[10:51:53] ABILIS_CPX:init res:tftp

COMMAND EXECUTED

35.1.2. TFTP resource parameters

Use the command below to display the parameters of the resource; the d p tftp ? command shows the meaning of parameters.

[13:07:41] ABILIS_CPX:d p tftp

RES:Tftp ----------------------------------------------------------------------
Run    DESCR:Trivial_File_Transfer_protocol
       LOG:NO        ACT:YES   udp-locport:69   srv-sess:10   TOS:0-N
       RTY:5         TOUT:3    WRITE-PERMISSIONS:NO
       IPSRC:127.000.000.001   IPSRCLIST:PrivateIpAdd
       WDIR:C:\APP\TFTP\

Reliability, C=Min. Monetary Cost] - 'bbbbbb', i.e. DS value bit by bit, where 'b' can be [0, 1]. Default is 0-N.

RTY

Number of retransmissions [1..30]. Default is 5.

TOUT

Time that TFTP waits for TFTP peer responses [1..15 sec.]. Default is 3.

WRITE-PERMISSIONS

Specifies the write permissions [NO: write operations are disabled, YES: all write operations are enabled, IF-EXISTS: write operations are enabled only if file already exists]. Default is NO.

IPSRC

Incoming requests: accepted source IP address [*, 1-126.x.x.x, 127.0.0.1, 128-223.x.x.x]. Default is 127.0.0.1.

IPSRC-LIST

Incoming requests: name of the IP/IR/RU/MR list for source IP address acceptance [#, 0..9, a..z, A..Z, _]. Default is "PrivateIpAdd".
