drop/nodrop
Determines if the DAG card's memory holes are de-coupled.
In
drop mode, the memory holes are de-coupled. If the data rate on one memory hole slows, the data
rate on any other memory holes is not affected. The dropping of packets occurs at the individual
stream's burst manager.
In
nodrop mode, the memory holes are coupled. The speed of the slowest memory hole determines the
overall speed of the data rate. The dropping of packets occurs at the port.
dagconfig drop
dagconfig nodrop
enable/disable
Sets whether this DAG card captures data on the defined port (a or b).
dagconfig -d0 enablea
dagconfig -d0 disablea
dagconfig -d0 enableb
dagconfig -d0 disableb
•
DAG card ports are enabled by default. You do not need to use
dagconfig
to enable the card in
order to begin capture unless you have previously disabled it.
•
On some firmware images changes to this option may not be applicable.
eql/noeql
Sets or unsets equipment loopback. For testing set to eql mode and normal operation set to noeql
mode.
eql mode loops transmit data from the host back to the PCIe Gen 2.0 bus.
dagconfig eql
dagconfig noeql
eth
Sets framer into ETH receive mode. Image dependent - only operates in Ethernet images
dagconfig eth
fcl/nofcl
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.
dagconfig fcl
dagconfig nofcl
