eql/noeql
Sets or unsets equipment loopback. For testing set to
eql
mode and normal operation set to
noeql
mode.
Note:
eql
mode loops transmit data from the host back to the PCIe bus.
Example
dagconfig eql
dagconfig noeql
fcl/nofcl
Note:
Sets or unsets Facility loop back. For testing set to
fcl
mode and normal operation
set to
nofcl
mode.
FCL retransmits the data received and also send it to the host.
Example
dagconfig fcl
dagconfig nofcl
laser/nolaser
Enables/disables the transmit laser on for the optical transceivers.
Example
dagconfig laser
dagconfig nolaser
mem
You can split the DAG card's allocated memory between the receive and transmit stream
buffers to suit your own requirements. The split is displayed as a ratio as shown below:
mem=X:Y
where:
X
is the memory allocated in MB to the
rx
stream
Y
is the memory allocated in MB to the
tx
stream.
If there are multiple
rx
or
tx
streams memory can be allocated to each stream:
mem=X:Y:X:Y:X:Y
Buffer_size
(page ) and
rx and tx Streams
(page ) are related to
mem
.
Example
You can split 128MB of memory evenly between the
tx
and
rx
streams using:
dagconfig –d0 mem=64:64
Note:
You can not change the stream memory allocations while packet capture or
transmission is in progress.
nic / nonic
Note:
From DAG software 3.1.0 onwards
nic/nonic
is replaced by
auto_neg/noauto_neg
.
Both options are valid and still can be used.
auto_neg/noauto_neg
is not supported
by some older cards. See
auto_neg / noauto_neg.
(page )
overlap/nooverlap
Configures the
rx
and
tx
memory hole to be overlapped. This enables in-line forwarding
without copying the data across the memory holes.
Example
dagconfig overlap
dagconfig nooverlap
Note:
This option is only applicable on firmware images containing TX.
