4.3 Configuration in WYSYCC Style
Description Configuration in WYSYCC is the 'What You See You Can Change' style.
Running the command '
dagfour'
alone shows the current configuration.
Each of the items displayed can be changed as follows:
Configuration
options default
set card to normal defaults.
[no]nic
[un]set nic mode.
[no]eql
[un]set equipment loopback. This is for testing only.
(en|dis)ableA
enable or disable port A for capture.
(en|dis)ableB
enable or disable port B for capture.
[no]varlen
dis/enable variable length capture. Otherwise record
length padded to slen
slen=X
capture packets of X bytes long.
long=X
allow 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.
txonly
Assign all buffer memory to transmit streams.
rxtx Assign buffer memory to transmit and receive streams.
Auto-negotiate The DAG 4.3GE can operate in one of two modes, nic and nonic.
The nic mode assumes that the card is connected directly to a Gigabit
Ethernet switch or card with a full-duplex cable, and the DAG will
perform Gigabit Ethernet auto-negotiation.
The nonic mode is intended for use with optical fibre splitters. The receive
socket of the DAG port is connected to the output of an optical splitter that
is inserted into a network link between two other devices, and the transmit
socket of the DAG is unconnected.
In this mode, Gigabit Ethernet auto-negotiation is not performed. One
splitter on each DAG receive port can then be used to monitor each
direction of a full-duplex Gigabit Ethernet link.
Ports
To affect one port,
c
ommands are applied to both ports by default. To
affect only one port, use the
–a or –b options
. To disable a port for
capturing, use the
disablea
and
disableb
commands.
