Cabletron Systems SEHI-32/34 Status, Media Type, 2-14, Using the SEHI Hub View, Active Users

Using the SEHI Hub View

•Inactive — 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 — The selected port does not support the Link feature, so the SEHI cannot determine link status; this value will show only for thin coax (BNC), AUI, or transceiver ports.

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.

•Unknown — The SEHI can’t determine a link status.

Status

The port’s Status can be one of three states:

•Segmented—A port becomes segmented (that is, disabled by the repeater module) when the port experiences 32 consecutive collisions, or when the port’s collision detector is on for longer than approximately 2 to 3 milliseconds.

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 “no link” condition).

•Active —The port is operating normally.

•Unknown — The SEHI cannot determine port status.

Active Users

Each active source address communicating through the port is counted as an active user. If Active Users is greater than one, it indicates that the port is supporting a trunk connection.

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

•Multi-Mode Fiber: SMA EPIM
