Setting BofL Retries

By default, the router makes five attempts to transmit a BofL message before

declaring the Ethernet interface down. With router redundancy enabled, the

default is four attempts.

You can specify the number of transmission attempts, from 1 to 60 retries, before

the router declares the circuit down. You can only do this by using the BCC.

To specify the number of retransmission attempts, access an existing Ethernet line

service and enter:

bofl-retries

integer

is the number of BofL retries. You can accept the default value of 5 or

enter any integer from 1 to 60.

Set the number of retransmission attempts in conjunction with the time period

between transmission of BofL attempts and the BofL timeout period to decrease

or increase the time it takes the router to declare an interface down.

For example, to set the number of BofL retries to 10, enter the following

command sequence:

box#

ethernet slot 13 connector 1

ethernet/13/1#

bofl-retries 10

Setting the BofL Timeout Divisor

By default, the router uses the value you specify for the BofL timeout period to

determine the time period between transmissions of BofL messages from an

Ethernet interface. The actual interval between BofL transmissions is the value of

the BofL timeout divided by the value of the BofL timeout divisor. When set to the

default value of 1, the BofL timeout divisor has no effect on the BofL timeout

value. When set to a value greater than 1, the BofL timeout divisor reduces the

value of BofL timeout.

When you configure router redundancy on an interface, Nortel Networks

recommends that you set the value of the BofL timeout divisor to 10 to reduce the

time between BofL transmissions, which reduces the time it takes the router to

declare a circuit down.
