This section describes procedures to create parameter instances for Subscribers 1, 2, and
3.
The QoS client creates global parameter instances to provide a minimal level of default
service for the router. In this portion of the example, the QoS client configures 2 Mbps of
data traffic and configures a scheduler weight of 1 for Subscriber 1. For Subscribers 2 and
3, the QoS client then configures a maximum of 2 Mbps of video bandwidth and 1 voice
call.
To create a global parameter instance:
Create a global parameter instance for max-subscriber-bandwidth with a value of
1.
2000000.
Create a global parameter instance for subscriber-weight with a value of 1.
2.
Create a global parameter instance for subscriber-video-bandwidth with a value of
3.
2000000.
Create a global parameter instance for max-100Kbps-voice-calls with a value of 1.
4.
host1(config)#qos-parameter max-subscriber-bandwidth 2000000
host1(config)#qos-parameter subscriber-weight 1
host1(config)#qos-parameter max-subscriber-video-bandwidth 2000000
host1(config)#qos-parameter max-100Kbps-voice-calls 1
Instead of creating global parameter instances, the QoS client can create different
parameter instances for the DSLAMs that correspond to the S-VLAN nodes shown in
Figure 61 on page 229. In this portion of the example, the QoS client creates 1 Mbps video
streams by default on DSLAM 1, rather than the 2Mbps global parameter instance.
Specify the Fast Ethernet interface in slot 9, port 0.
1.
Attach the QoS parameter max-subscriber-video-bandwidth to S-VLAN 1.
2.
host1(config)#interface fastEthernet 9/0
host1(config-if)#svlan 1 qos-parameter max-subscriber-video-bandwidth 1000000
host1(config-if)#exit
The QoS client creates a parameter instance for Subscribers 1, 2, and 3.
Configure the basic-data service for Subscriber 1.
1.
a. Specify the Fast Ethernet interface in slot 9, port 0.
b. Attach the QoS profile subscriber-data-service to the subscriber's Fast Ethernet
interface.
host1(config)#interface fastEthernet 9/0.1
host1(config-subif)#qos-profile subscriber-data-service
host1(config-subif)#exit
