Table 3-24. Interface Frame Relay Options (3 of 3)

LMI Clearing Event (N3)

Possible Settings: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Default Setting: 1

Configures the LMI-defined N3 parameter, which sets the number of error-free messages that must be received before clearing an error event. Applies to both the user and network sides of a UNI.

1 – 10 – Specifies how many error-free messages it will take to clear the error event.

LMI Status Enquiry (N1)

Possible Settings: 1, 2, 3, 4, . . . 255

Default Setting: 6

Configures the LMI-defined N1 parameter, which sets the number of status enquiry polling cycles that the user side of the LMI initiates before a full status enquiry is initiated. Applies to the user side of a UNI only.

1 – 255 – Specifies the number of status enquiry polling cycles that can be initiated before a full status enquiry is initiated.

LMI Heartbeat (T1)

Possible Settings: 5, 10, 15, 20, 25, 30

Default Setting: 10

Configures the LMI-defined T1 parameter, which sets the number of seconds between the initiation of status enquiry messages on the user side of the LMI. Applies to the user side of a UNI only.

5 – 30 – Specifies the number of seconds between the initiation of status enquiry messages in increments of 5.

LMI Inbound Heartbeat (T2)

Possible Settings: 5, 10, 15, 20, 25, 30

Default Setting: 15

Configures the LMI-defined T2 parameter, which sets the number of seconds between the receipt of status enquiry messages on the network side of the LMI. Applies to the network side of a UNI only.

5 – 30 – Specifies the number of seconds between the receipt of status enquiry messages in increments of 5.

LMI N4 Measurement Period (T3)

Possible Settings: 5, 10, 15, 20, 25, 30

Default Setting: 20

Configures the LMI-defined T3 parameter, which is the time interval (in seconds) that the network side of the LMI uses to measure the maximum number of status enquiry messages that have been received (N4) from the user side.

5 – 30 – Specifies the interval of time in increments of 5.
