+CGTFT – Traffic Flow Template
<destination port range>
: string type. The string is given as dot-separated numeric
(0-65535) parameters in the form "f.t".
<source port range>
:string type. The string is given as dot-separated numeric (0-
65535) parameters in the form "f.t".
<ipsec security parameter index (spi)>
: numeric value in hexadecimal format.
The value range is from 00000000 to FFFFFFFF.
<type of service (tos) (ipv4) and mask / traffic class (ipv6) and mask>
:
string type. The string is given as dot-separated numeric (0-255) parameters in the
form "t.m".
<flow label (ipv6)>
: numeric value in hexadecimal format. The value range is from
00000 to FFFFF. Valid for IPv6 only.
<direction>
: a numeric parameter which specifies the transmission direction in
which the packet filter shall be applied.
0 - Pre-Release 7 TFT filter (see 3GPP TS 24.008 [8], table 10.5.162)
1 - Uplink
2 - Downlink
3 - Birectional (Up & Downlink) (default if omitted)
Some of the above listed attributes may coexist in a Packet Filter while others
mutually exclude each other, the possible combinations are shown in 3GPP TS
23.060 [47].
AT+CGTFT?
The read command returns the current settings for all Packet Filters for each
defined context.

AT+CGTFT =?
The test command returns values supported as a compound value. If the MT
supports several PDP types, the parameter value ranges for each PDP type returned
on a separate line. TFTs shall be used for PDP-type IP and PPP only. For PDP-type
PPP a TFT is applicable only when IP traffic is carried over PPP. If PPP carries
header-compressed IP packets, then a TFT cannot be used.
