Opened: Oct 11, 2021
Severity: 2-Critical


Line-dma agent is the underlying layer of tcpdump in the VELOS/rSeries family of chassis and appliance products When it is not running, or if it cores or is otherwise not available and a client wants a tcpdump capture, tcpdump may core.


Packet capture will be affected and will not work


-- line-dma-agent is not functional at start, or at some later point in time during the tcpdump capture -- a client requests a tcpdump capture



Fix Information

Tcpdump does not core anymore, and will retry line-dma-agent connection when clients ask for capture

Behavior Change
