Cabletron Systems EMM-E6 manual Status, Media Type

Using the EMM-E6 Hub View

Not Supported — The selected port does not support the Link feature, so the EMM-E6 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 hub so equipped.

Unknown — The EMM-E6 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 EMM-E6 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 two (or one for firmware versions previous to 2.00.16), it indicates that the port is supporting a trunk connection.

Media Type

Indicates the type of cable segment connected to the port. MIMs generally support a single media type. The supported media types are:

BNC (thin coax)

AUI

Transceiver Port AUI

Twisted Pair: RJ45 conn(ector)

Twisted Pair: DB9 conn

Twisted Pair: RJ71 conn

Multi-Mode Fiber: SMA conn

Multi-Mode Fiber: ST conn
