A-3
Parameter: BofL Timeout
Path: Configuration Manager > XCVR Connector > Edit Line > Edit CSMA/CD
Parameters
Default: 5 (4 if router redundancy is enabled)
Options: 1 to 60 seconds
Function: Specifies the time between transmissions of Breath of Life messages from this
Ethernet interface. Timeout will occur if five periods elapse without a successful
BofL message transmission. When timeout occurs, the router disables and
reenables the Ethernet interface.
This parameter is valid only if you set BofL Enable to Enable.
Instructions: Accept the default BofL timeout of 5 seconds, or specify a new value up to 60
seconds.

Parameter: Hardware Filter

Edit CSMA/CD Parameters
Default: Disable (the default changes to Enable when, while adding the circuit, you reply
OK to the prompt:
Do you want to enable Hardware Filters on this circuit?)
Options: Enable
|
Disable
Function: Enables filtering hardware in the link or net module to drop local frames at the
interface instead of copying them into system memory. Enabling hardware
filters improves bridging software performance because router resources are not
used to receive and reject local frames.
Instructions: Set to Enable only if you enabled the bridge software and the link or net module
has hardware filters.
