Monitoring Hub Performance2-19Using the EMM-E6 Hub View• AUI EPIM• Transceiver Port AUI EPIM• Twisted Pair: RJ45 EPIM• Multi-Mode Fiber: SMA EPIM• Multi-Mode Fiber: ST EPIM• Single-Mode Fiber: ST EPIM• Hardwired AUI EPIM• Unknown (for boards that don’t support media type)Topology TypeIndicates how the port is being used. The available types are:• Station—The port is receiving packets from no devices, from a single device,or from two devices. Note that a port in station status may actually beconnected to multiple devices; station status simply indicates that no morethan two devices are currently active.• Trunk—The port is receiving packets from three or more devices; it may beconnected to a coax cable with multiple taps, or to a repeater or another MIM.Viewing the IP Address TableYou can use the IP Address Table option on the Device menu to view the MAC(hardware) addresses of all installed interfaces, along with their associatedinterface numbers, interface types, interface descriptions, and any assigned IPaddresses. The interface numbers 1-4 correspond to channel, or network,designations A, B, C, and D; interfaces available via BRIM port E will be indexedstarting at 5, and those available via BRIM port F will follow.NOTEIf you use the Trunk Type option on the Port menu to manually change a port’s topologystatus from Force Trunk to Not Forced, any status change from trunk to station will notbe reflected in the port display until the current cycle of the Source Address timer iscomplete. See Chapter 6, Source Addressing, for more information on the timer.Older versions of EMM-E6 firmware (previous to revision level 2.00.16) use slightlydifferent definitions of station and trunk status: station ports are defined as those whichare detecting no source addresses or only a single source address; trunk ports are thosedetecting two or more. If you have any questions about which definitions are employed byyour version of firmware, or if you would like information about upgrading yourEMM-E6 firmware, contact the Cabletron Systems Global Call Center. Also, see Chapter6, Source Addressing, and Chapter 7, Security, for more information about station andtrunk status.NOTEYou cannot change or assign an IP address from this window or from any other SPMAapplication.
