Monitoring Hub Performance 2-15
Using the SEHI100TX Hub View
¥Active Ñ The port has a valid connection with the device at the other end of
the portÕs cable.
¥Inactive Ñ The device at the other end of the cable is turned off, there is a
break in the cable, or there is no device or cable connected.
¥Not Supported Ñ The selected port does not support the Link feature, so the
SEHI100TX cannot determine link status; this value will show only for thin
coax (BNC), AUI, or transceiver ports.
¥Unknown Ñ The SEHI100TX canÕt determine a link status.
Status
The portÕs Status can be one of three states:
¥Segmented Ñ A port becomes segmented (that is, disabled by the repeater
module) when the port experiences 32 consecutive collisions, or when the
portÕs collision detector is on for longer than approximately 2 to 3
milliseconds.
¥Active Ñ The port is operating normally.
¥Unknown Ñ The SEHI100TX cannot determine port status.
Active Users
This Þeld is not supported by the SEHI100TX.
Media Type
Indicates the type of cable segment connected to the port. The supported media
types are:
¥ Twisted Pair: RJ45 conn(ector)
¥ BNC EPIM
¥ AUI EPIM
¥ Transceiver Port: AUI EPIM
¥ Twisted Pair: RJ45 EPIM
NOTE
The fact that thin coax (BNC), AUI, and transceiver ports do not support the link feature
can cause some misleading port status indicators: for example, a BNC port may show as
segmented when, in fact, the cable has been disconnected; or an AUI or transceiver port
may appear to have an active link when no cable has been attached. You should keep these
anomalies in mind when troubleshooting a device so equipped.
NOTE
Because they do not support the link feature, thin coax (BNC) ports will display as
segmented when there is no cable or terminator attached or the cable or terminator has
been disconnected (i.e., a Òno linkÓ condition).
