Topology Type

Indicates 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 be connected to multiple devices; station status simply indicates that no more than two devices are currently active.

•Trunk—The port is receiving packets from three or more devices; it may be connected to a coax cable with multiple taps, or to a repeater or another MIM.

NOTE

If you use the Trunk Type option on the Port menu to manually change a port’s topology status from Force Trunk to Not Forced, any status change from trunk to station will not be reﬂected in the port display until the current cycle of the Source Address timer is complete. 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 slightly different deﬁnitions of station and trunk status: station ports are deﬁned as those which are detecting no source addresses or only a single source address; trunk ports are those detecting two or more. If you have any questions about which deﬁnitions are employed by your version of ﬁrmware, or if you would like information about upgrading your EMM-E6 ﬁrmware, contact the Cabletron Systems Global Call Center. Also, see Chapter 6, Source Addressing, and Chapter 7, Security, for more information about station and trunk status.

Viewing the IP Address Table

You can use the IP Address Table option on the Device menu to view the MAC (hardware) addresses of all installed interfaces, along with their associated interface numbers, interface types, interface descriptions, and any assigned IP addresses. The interface numbers 1-4 correspond to channel, or network, designations A, B, C, and D; interfaces available via BRIM port E will be indexed starting at 5, and those available via BRIM port F will follow.

NOTE

You cannot change or assign an IP address from this window or from any other SPMA application.
