Figure 23. Example of Hierarchical Scheduling
Quick references
The following sections provide a minimal “standard” link scheduler configuration for the case where voice and
data share a (DSL/cable) modem link. You will also find a command cross reference list for administrators
familiar with Cisco’s IOS QoS features and having to become acquainted with SmartWare QoS configuration.
Setting the modem rate
To match the voice and data multiplexing to the capacity of the access link is the most common application of
the SmartWare link scheduler.
1. Create a minimal profile.
profile service-policy modem-512
rate-limit 512 header-length 20 atm-modem
source traffic-class local-voice
priority
2. Apply the profile just created to the interface connected to the modem.
context ip
interface wan
use profile service-policy modem-512 out
Some explanations:
• “modem-512” is the title of the profile which is referred to when installing the scheduler
