# Creating Parameter Instances

You can create QoS parameter instances globally, for an interface, or for a subinterface.

Tasks to create parameter instances are:

- Creating a Global Parameter Instance
- Creating a Parameter Instance for an Interface
- Creating a Parameter Instance for an ATM VP
- Creating a Parameter Instance for an S-VLAN

## Creating a Global Parameter Instance

To create a global parameter instance:

- Create a parameter instance in Global Configuration mode.
  `
  host1(config)#qos-parameter max-subscriber-bandwidth 6000000
  `

## Creating a Parameter Instance for an Interface

To create a parameter instance for an interface:

1. Specify an interface.
   `
   host1(config)#interface atm 11/0.1
   host1(config)#interface gigabitEthernet 2/0
   `
2. Specify the parameter name and the value.
   `
   host1(config-subif)#qos-parameter max-subscriber-bandwidth 6000000
   `

## Creating a Parameter Instance for an ATM VP

Use this procedure to attach a parameter instance to a VP on the interface. Optionally, use the qos-profile keyword to attach a parameter instance to a QoS profile.

To create a parameter instance for an ATM VP:

1. Configure the ATM VP.
   `
   host1(config)#interface atm 2/0
   host1(config-if)#atm vp-tunnel 4
   `
2. Do either of the following:
   - Attach the parameter instance to an ATM VP on the interface.
     `
     host1(config-if)#atm-vp 4 qos-parameter max-subscriber-bandwidth 375000
     `
   - Attach the parameter instance and associate with the QoS profile.
     `
     host1(config-if)#atm-vp 4 qos-profile video qos-parameter max-subscriber-bandwidth 375000
     `

## Creating a Parameter Instance for an S-VLAN

Use this procedure to attach a parameter instance to a specified S-VLAN ID on the interface. Optionally, use the qos-profile keyword to attach a parameter instance to a QoS profile.

To create a parameter instance for an S-VLAN:

1. Specify the Ethernet interface and create the VLAN.
   `
   host1(config)#interface gigabitEthernet 3/0
   host1(config-if)#encapsulation vlan
   host1(config-if)#interface gigabitEthernet 3/0.1
   `
2. Specify the S-VLAN ID.
   `
   host1(config-if)#svlan id 1 202
   `
3. Attach the parameter instance to an S-VLAN ID on the interface.
   `
   host1(config-if)#svlan 202 qos-parameter max-subscriber-bandwidth 6000000
   `
