Port state information includes link state (the color code) and admin state (on or off).
Chapter 3 Link/Seg Traps About Link and Segmentation traps; enabling and disabling these traps at the device, module, and port levels Among the traps which Cabletron devices are designed to generate are traps which indicate when a repeater port gains or loses a link signal, when the repeater segments (disconnects) a port due to collision activity, and when a segmented port becomes active again. In some networks, these Link and Segmentation traps may be more information than a network manager wants to see.
Link/Seg Traps NOTE Unterminated BNC (thin coax) ports appear in the Hub View as segmented ports. When you attach a thin coax cable or a 50 Ω terminator to a port, the repeater generates a portUnsegmenting trap; when you remove the cable or terminator, the repeater generates a portSegmenting trap. Note also that devices at both ends of the cable will generate the portUnsegmenting and portSegmenting traps, even if only one end of the cable has been disconnected.
Link/Seg Traps from the Hub View: 1. Click on to display the Device menu. 2. Drag down to Link/Seg Traps and release. from the command line (stand-alone mode): 1.

Appendix A SEHI100TX MIB Structure SEHI100TX management information base configuration IETF MIB Support In addition to its proprietary features, the SEHI100TX currently supports the following IETF MIB: ¥ RFC 1213 MIB for Network Management of TCP/IP-based Internets: MIB-II SEHI100TX MIB Structure CabletronÕs newer intelligent devices Ñ like the SEHI100TX Ñ organize MIB data into a series of Òcomponents.Ó A MIB component is a logical grouping of MIB data, and each group controls a deÞned set of objects.
SEHI100TX MIB Structure information in the other components, even if those components have different community names; the Chassis MGR community names are the same as those assigned via Local Management. SEHI100TX LIM The SEHI100TX LIM, or Local Management, component contains the objects that provide out-of-band management via the Console port on the SEHI100TXÕs front panel. No objects from this component are used for remote management.
SEHI100TX MIB Structure NOTE The set of community names you assign via Local Management are those which apply to the SEHI100TX Chassis MGR MIB component. Newer versions of devices with this component-based MIB architecture have been simpliÞed somewhat; these devices support a single, global set of community names, with small modiÞcations added automatically to accommodate multiple instances of the same MIB component (such as network components).
