Figure 19. Example of Hierarchical Scheduling

Quick references

The following sections provide a minimal “standard” link scheduler configuration for the case where a (DSL/cable) modem link is shared for all traffic. You will also find a command cross reference list for adminis- trators familiar with Cisco’s IOS QoS features and having to become acquainted with OnSite QoS configura- tion.

Setting the modem rate

To match the data multiplexing of different traffic types to the capacity of the access link is the most common application of the OnSite link scheduler.

1.Create a minimal profile.

profile service-policy modem-512 rate-limit 512 header-length 20 atm-modem source traffic-class critical_q

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
