Partition - A port is temporarily partitioned when a line error
or too many collisions are detected on the attached collision
domain. While automatically partitioned, the port continues to
receive data from the segment. However, data is not
transmitted onto the segment. When the problem is corrected
or a valid data packet is received through the port, it is
automatically reconnected. When partitioning occurs, the
port’s
Partition/Disable LED will be continually lit. Otherwise,
this LED should be OFF.
Disable - Disabling a port is the same as manually partitioning it,
except that you must also manually reconnect it. For example,
to prevent a certain device from accessing the network or to
reduce network traffic you may opt to disable the port. No
incoming packet transmission can occur on a disabled port.
Ports can be disabled/enabled using the VT-100 console
interface.
