3Com MSR 50, MSR 30 manual Layer 2 module interface view, port group view, 1781

	1781
View	Layer 2 module interface view, port group view
Parameters	inbound: Configures LR for data streams received by the interface. For a device
	which cannot be installed with an external interface module or when the number
	of the interfaces is 4 or 9, this argument is not supported.
	outbound: Configures LR for data streams sent by the interface.

cir committed-information-rate: CIR, with the value being 128, 256, 512, 1024, 2048, 4096 or 8192 kbps for a device which cannot be installed with an external interface module or when the number of the interfaces on a layer 2 module is 4 or

9.If the number of interfaces on a layer 2 module is 16, 24 or 48, the value ranges from 64 to 1000000, in steps of 64 kbps.

cbs committed-burst-size: CBS, with the value being 4096, 8192, 16384, 32768, 65536, 131072, 262144, 524288 bytes when the number of the interfaces on a layer 2 module is 16, 24 or 48. It defaults to 4096 bytes. If the cbs committed-burst-sizeconfigured by the user is not a specified one, the system automatically selects the nearest one. For a device which cannot be installed with an external interface module or when the number of the interfaces is 4 or 9, this argument is not supported.

ebs excess-burst-size: This argument is not supported on the interface on a layer 2 module for a device which cannot be installed with an external interface module or when the number of the interfaces on the layer 2 module is 4, 9, 16, 24 or 48.

Description Use the qos lr command to limit the transmitting or receiving rate of the interface.

Use the undo qos lr command to remove the limit.

Execute the command in interface view, and the setting is valid on the current interface only. Port group is supported when the number of the interfaces on a layer 2 module is 16, 24 or 48. If this command is executed in port group view, the setting is valid on all ports.

Examples # Limit packet-forwarding rate of interface Ethernet1/0 to the normal rate 64 kbps. The CBS value is 8192 bytes.
