Frame Sizes
Displays a percentage for each active port that represents what portion of that port’s traffic is of a specific size, measured in bytes. You can display any one of the following frame sizes:
•Runts (packets with fewer than 64 bytes)
•
•
•
•
•
•Giants (packets with more than 1518 bytes)

Port Type
Provides the following administrative information about the port:
•Admin/Link Status indicates the connection status of the port:
-ON indicates that the port has a valid link signal or does not support a link signal.
-OFF indicates that the port has been turned off through management action.
-NLK (No Link) indicates that the port does not have a link to a device at the other end of the cable, or that there is no cable attached.
-SEG (Segmented) indicates that the port has been segmented by the repeater due to an excessive collision level.
NOTE |
Because BNC thin coax, AUI, and transceiver ports do not support the link feature, the displayed Admin/Link status for those ports may be misleading: for example, a BNC port will display as segmented when, in fact, there is no cable or terminator attached or the cable has been disconnected; an AUI or transceiver port will display as on (with a valid link signal) even when no cable is attached. Be sure to keep these anomalies in mind when troubleshooting a device so equipped.
•Admin Status displays either ON or OFF, an indication of whether management has the port enabled or disabled. A port can be ON but not operational; for example, under the Admin display, ports that are segmented or not linked are shown as ON.
