Off Device connected at 100Mbps.
Partitioned ports
A port is automatically disabled (partitioned) by the hub when an invalid
condition occurs, such as too many consecutive collisions.
Once the hub is able to transmit data to the port collision free, the hub
automatically re-enables (unpartitions) the port. Clients are usually not
affected by a partitioned port because the port is often unpartitioned very
quickly.
Usually, a partitioned port indicates an overloaded network or a
malfunctioning device (such as an adapter card) on the network. To alleviate
an overloaded network, divide the network into smaller segments so that
fewer devices share the same fixed amount of bandwidth.
