Command History
Usage Guidelines
debug atm t3e3 data command
Use the
debug atm t3e3 data
command to display the incoming packet indications. Each incoming
packet transferred by direct memory access (DMA) to the host memory by the SAR will cause a packet
indication.
debug atm t3e3 flow command
Use the
debug atm t3e3 flow
command to display flow control indications.
When traffic sent to the SAR exceeds the peak cell rate for a particular virtual circuit (VC), the SAR
indicates this to the host by sending flow control indications. These indications inform the host that
either the high watermark or the low watermark has been reached for that VC queue.
When a high watermark is received from the SAR, indicating that the VC queue is full, the host will stop
sending packets to the SAR until a low watermark indication is received. A low watermark indicates that
the VC queue has been drained sufficiently to receive additional packets.
data
Displays debug messages for incoming packet indications.
flow
Displays debug messages for flow control indications.
pa
Displays debug messages for online insertion or removal (OIR) of the ATM
T3/E3 network module.
sar
Displays debug messages for blocking commands sent to the segmentation
and reassembly (SAR) and their acknowledgments.
trace
Displays debug messages that give the hexadecimal representation of
commands sent to the SAR and their acknowledgments.
