Managing Ethernet MicroLAN Switches5-22Trap SelectionTo access the board-level Trap Selection window:1. Click on the appropriate Module Index to display the Module menu.2. Select the appropriate repeater channel (A - H) to reveal the board-levelRepeater menu.3. Click on Trap Selection. The Board Trap Selection window will appear.To access the port-level Trap Selection window:1. Click on the appropriate Port index to display the Port menu.2. Click on Trap Selection. The Port Trap Selection window will appear.The Board Trap Selection window is similar to the Repeater Trap Selectionwindow displayed in Figure 5-10, and serves the same function (since, for theEthernet MicroLAN Switch, a “board” is the equivalent of a repeater channel). Ifall port-level trap settings are uniform at the current level of device management(i.e., a given trap is either set to enabled or disabled for all ports on a repeatednetwork segment), the check box for a given trap will return with an enabled ordisabled state, as appropriate. If port-level trap settings are mixed at the currentlevel of management (i.e., a given trap is enabled at some ports and disabled atother ports on the selected repeater channel), the check box for a given trap willbe grayed, as illustrated above for Link State traps.When you are changing trap settings at the Repeater or Board level, a check boxthat is left gray for a given trap is treated as a “No SET” indicator, so that thecurrent settings at the individual port level with respect to that trap will not beoverridden when you are changing other trap settings.The Port Trap Selection window is similar to the other Trap Selection windows;however the gray mixed-mode will never appear when you first open thewindow (since at the port-level, a given trap can only be either enabled ordisabled – not some combination of the two).You can change trap settings from any level window; however, if you haveestablished individual trap settings for any ports, remember that enabling anddisabling traps from the repeater- or module-level windows will override thoseindividual setting. Remember, too, that setting trap selection state at the repeaterand module levels accomplishes the same thing, as each “board” on the EthernetMicroLAN Switch is a repeated network.Trap DefinitionsYou can enable or disable the following kinds of traps:Link State TrapsSome Cabletron Ethernet repeater ports – including RJ45 twisted pair and fiberoptic ports – generate a link signal to monitor the status of their connection withthe device at the other end of the cable segment. If the cable is removed or broken,
