Card
Configuration
Options
Running the command '
dagthree'
alone shows the current configuration.
Each of the items displayed can be changed as follows:
default
set card to normal defaults
[no]fcl
(un) set facility Loopback. Should be set to nofcl.
Mainly used for testing
[no]eql
(un)set equipment loopback. Should be set to
noeql. Mainly used for testing
[no]varlen
(dis)enable variable length capture. Otherwise
record length padded to slen
slen=X
Capture packets of x bytes long
[no]align64
Generate records with 64-bit alignment [default 32-
bit]
mem=X:Y
Configure memory allocated to streams 0, 1
rxonly
Assign all buffer memory to receive streams
[no]rxmonitor
Used with DS3X monitor tap. Enabling the pre-
amplifier adds approx 20dB of linear amplification
[no]descramble
(dis)enable receive cell scrambling. ATM only
(no)discard
When enabled the FCS bytes are discarded. When
disabled the FCS bytes are passed on. This option
is ignored when
nocrc
is set
nocrc/crc16/crc
32
Sets the expected size of the crc for the receive
packet to process. HDLC only
ds3_cbit
Framing DS3 CBit
ds3_cbit_if
Framing DS3 CBit Internal Fractional
ds3_cbit_ef
Framing DS3 CBit External Fractional
ds3_cbit_ff
Framing DS3 CBit Flexible Fractional
ds3_m23
Framing DS3 M23
ds3_m23_if
Framing DS3 M23 Internal Fractional
ds3_m23_ef
Framing DS3 M23 External Fractional
ds3_m23_ff
Framing DS3 M23 Flexible Fractional
Hdlc
Selects bit-synchronous HDLC mapping. This is
currently the only option supported
