mem
It is possible to split the DAG card's allocated memory between the receive and transmit stream buffers
to suit specific requirements. Where a DAG card does not support transmit, set the transmit stream
buffers to 0 (zero). 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. Only applicable if the DAG card supports
transmit.
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 26) and rx and tx Streams (page 31) are related to mem.
You can split 128MB of memory evenly between the tx and rx streams using:
dagconfig –d0 mem=64:64
You cannot change the stream memory allocations while packet capture or transmission is in progress.
For information on calculating the required stream buffer size, see Guidance for stream buffer sizing
(page 71).
nic/nonic
Modes: 10G Ethernet only.
This token operates very differently from the previous nic/nonic token.
In nic mode, the DAG card must have a receive signal present to transmit packets. The DAG card
transmits the ‘Remote Fault’ ordered set when no signal is present on its receiver (compliant mode).
In
nonic mode this behavior is disabled, allowing the DAG card to transmit packets without having a
receive signal present (non compliant mode).
dagconfig nic
dagconfig nonic
For 1G Ethernet use auto_neg / noauto_neg (page 26)
nodelay
Applicable to TR-TERF. Disables Relative Timed Release mode (No Delay Mode).
In
No Delay Mode
all packets are transmitted at the maximum rate permitted by the line interface, using
only minimum gaps between packets.
See also relative (page 30), time_mode (page 32
).
dagconfig nodelay
