Enabling or Disabling an Ethernet Interface
The router enables CSMA/CD line services when you add a 10 Mb/s or 100 Mb/s
Ethernet interface. You can disable and reenable the Ethernet interface without
moving physical cabling.
Enabling or Disabling Breath of Life Messages
With Breath of Life (BofL) enabled, the router sends polling messages from this
interface to all systems on the local network. BofL messages signify that the
Ethernet line is up and functioning normally.
BofL messages are enabled by default on every Ethernet interface. You can
disable and reenable BofL messages on an interface.
Setting the BofL Interval
When BofL is enabled, a network timeout will occur if five periods elapse without
a successful BofL message transmission. When timeout occurs, the router
automatically disables and reenables the Ethernet interface. For example, if you
set the BofL interval to 10 seconds, the interface must successfully transmit a
BofL message within 50 seconds.
The BofL interval is 5 seconds by default. You can change the interval of BofL
messages to a value from 1 through 60 seconds.
