    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.

  • Page 38: What Is A Link Trap

    Link/Seg Traps Unterminated BNC (thin coax) ports appear in the Hub View as segmented ports. When you attach a thin coax cable or a 50 NOTE 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.
