When a repeater detects a collision on any of the ports to
which it is transmitting, it transmits a jam signal to all of
the ports to which it is connected. This object specifies the
minimum amount of time a repeater transmits a jam signal after
it detects a collision. See the IEEE 802.3 standard for more
details regarding collision detection and handling.
Setting this object to jb96(1) causes the repeater to transmit
jam for at least 96 bit times after it detects a collision.
This setting complies with the IEEE 802.3 standard
specification for the minimum jam time.
Setting this object to jb128(1) causes the repeater to transmit
jam for at least 128 bits times after it detects a collision.
Some repeaters, designed prior to the development of the IEEE
802.3 specification, jam for a minimum of 128 bit times after
they detect collisions. It may be desirable for all the
repeaters on the LAN to perform the same collision handling
function. This setting provides a backwards compatibility mode
when older repeaters are present in the network.
Some implementations may not support setting this object to all
defined enumerated values. A badValue error is returned if an
attempt is made to set this object to an unsupported value.
Note: If an implementation supports multiple minimum jam time
settings, the default value for this object is
jb96(1).
Note: The state of this object is preserved when the repeater
undergoes a power-up reset.
