show interface cable service-flow
Field Description
Dir Indicates if this service flow is downstream (DS) or upstream (US).
Curr State Indicates the current run-time state of the service flow.
Active Time Indicates the length of time this service flow has been active.
Note Per the DOCSIS 1.1 specification, the show interface cable service-flow command uses bytes allocated
for a UGS service flow when calculating the throughput values for the service flow (see the Assumed
Minimum Reserved Rate Packet Size parameter, TLV 11 in the upstream and downstream service flow
configurations). Depending on the value of this parameter and the packet sizes of the actual traffic, this
could result in throughput values that appear to be greater than the maximum sustained rate. You can use
the stats option with the show interface cable command to display the actual byte counts.
