interface is shown, as is the duplex setting. If duplex was mismatched with the device on the
other end, the later collisions counter would most likely increment rapidly.
table on the 1900 family of switches. The MAC address table contains dynamic entries, which
are learned when the switch receives frames and examines the source MAC address. Two other
variations of entries in the MAC address table are important to switch configuration and are
outlined along with dynamic entries in the following list:
bridge/switch processing. In other words, when a frame is received, the source MAC of
the frame is associated with the incoming port/interface. These entries in the table time
out with disuse and are cleared whenever the entire table is cleared.
port, just as it would have been associated as a dynamic address. However, permanent
entries in the table never time out.
associated only with a particular port, with an additional restriction: Frames destined to
that MAC address must have entered via a particular set of incoming ports.
Duplex setting: Half duplex
Back pressure: Disabled
