Enabling and Disabling Ports
You may wish to isolate a port for one of the following reasons:
❏ Operational: Disabling a malfunctioning station
removes it from the network so it does not interfere
with the operation of the other stations.
❏ Security and administrative: Ports that are connected to
other hubs or to bridges can be isolated from other seg-
ments.
❏ Enhancing network performance: Disabling a port
when the network is heavily loaded and connectivity to
other segments is not needed can improve performance.
Identifying Errors
Sources of network errors should be identified and disabled. A high error
count or collision count could indicate a possible problem with that port or
the device connected to it.
