UCD Grant Size (microsec)
Upstream Channel Description (UCD) grant size. After a UCD change, this
specifies the size of grant to zero (which functions as a delay for cable
modems to digest the new UCD), in microseconds. By default, New UCD
Grant Size is set at 3000.
Perform the following task within interface cable <c/s/i> mode to set the
UCD grant size for an upstream channel.
.
Maximum Deferred Ranging Invitations
Maximum number of deferred ranging invitations. By default, Maximum
Deferred Ranging Invitations is set at 2.
You set maximum deferred ranging for an upstream channel by performing
the following tasks.
.
Task Command
1. Enable interface cable mode. interface cable <c/s/i>
2. Configure UCD grant size for an
upstream channel.
