IBM SC30-3681-08 Excess Burst Size, Assign Circuit Name, Is the circuit required for operation

Con®guring Frame Relay Interfaces

Notes:

1. If CIR is con®gured as 0 then the committed burst size is set to 0 and you are not prompted for a value. For additional information, see ªCommitted Burst (Bc) Sizeº on page 397.

Excess Burst Size

The maximum amount of uncommitted data in bits in excess of committed burst size that the network attempts to deliver during a measurement interval equal to (Committed Burst Size/CIR) seconds. Range is 0 to 2 048 000 bits. The maximum value is the value con®gured for excess burst size for the interface. For additional information, see ªExcess Burst (Be) Sizeº on page 397.

Assign Circuit Name

Indicates the ASCII string that is assigned to describe the circuit.

The default is unassigned.

Is the circuit required for operation

Specify Y or N to indicate whether the circuit is required for interface operation.

Does the circuit belong to a required PVC group

This prompt is displayed only for circuits that are required. Specify

Y or N to indicate whether the circuit should belong to a required

PVC group.

What is the group name

Enables you to specify the name of the required PVC group when the PVC is de®ned as belonging to a required group. Enter a question mark (?) for a list of currently de®ned groups.

Do you want to have compression performed

Enables you to specify whether or not the circuit will compress data

packets. This question appears only if compression is enabled on

the interface.

Note: If you enable compression on a PVC and exceed the

interface's compression circuit limit, you will get a message.

Compression will be performed on the circuit, if possible ±

that is, the active compression limit has not been exceeded

when the circuit becomes active. Compression limit includes

the number of compression contexts allocated to SVCs as

well as PVCs.

Do you want to have data encryption performed

Enables you to specify whether or not the circuit will encrypt data

packets. This question appears only if encryption is enabled on the

interface. The prompts for the encryption key will only appear if you

respond ªyesº (or ªyº) to this question.

Specifying the Encryption Key: The encryption key is 16

hexadecimal characters long. You must specify the encryption key

as a value between X©0000000000000000© and

X©FFFFFFFFFFFFFFFF©.

protocol-address

This command adds statically con®gured destination protocol

(protocol-name) addresses to the Frame Relay interface. Statically

con®gured destination protocol addresses are useful if neither Inverse ARP
