408 CHAPTER 18: CONFIGURING CABLE MODEM TERMINATION SYSTEMS
Configuring Admission Control
The admission control function allocates HFC interface bandwidth to service
flows, and prevents admission of flows when bandwidth is unavailable. The
admission control function sets aside bandwidth for unsolicited grant service
(UGS) service flows and UGS with activity detection (UGS/AD) service flows,
which are used to transmit voice traffic.
By default, admission control is disabled on an interface. Perform these tasks
to configure admission control on a cable interface:
Task Command
1. Access interface cable mode. interface cable <c/s/i>
2. Enable admission control for the
interface.
admission-control enable
3. Verify that admission control is
enabled.
show admission-control
4. Reserve a percentage of
bandwidth for UGS and UGS/AD
service flows on one or more
upstream ports.
The <port number> argument
specifies the upstream port for
which you are reserving
bandwidth.
The voice-bw-reserve <number>
argument specifies the percentage
of bandwidth reserved. Values
range from 0.0 to 100.0. The
default is 75.0 percent.
upstream <port number>
voice-bw-reserve <number>
5. Verify the bandwidth percentage
setting.
