Cabletron Systems EMM-E6 manual Configuring Source Address Traps

Source Addressing

•A port’s topology status (station or trunk) remains fixed while locking is in effect, even if the number of detected addresses changes.

•Any ports disabled due to a violation (or because they were unlinked when locking was enabled) must be manually re-enabled via their Port menus, and

•There are no additional Security features available.

If you are not sure which set of port locking features your device firmware supports, contact the Cabletron Systems Global Call Center.

Configuring Source Address Traps

The EMM-E6 can issue several different traps in response to changes in the Source Address Table; you can enable and disable certain of these traps for the repeater as a whole, and, if your device has very new firmware, they can also be enabled or disabled for each individual module and port.

NOTE

If the Module Traps and Port Traps buttons on the Repeater Source Address screen are grayed-out, your device firmware does NOT support the ability to enable and disable source addressing traps at the module and port levels. Contact the Cabletron Systems Global Call Center for information about upgrading your device firmware.

SPMA does not accept the trap messages; that task is left to your network management system. (See the appropriate network management system documentation for details about viewing trap messages.) When this utility is used in stand-alone mode, traps will either be ignored when they return to the workstation from which you are running SPMA for the EMM-E6, or they will turn up at another management workstation which has been configured to accept traps. Note also that, regardless of the configuration performed using this utility, NO traps will be sent by the device unless its trap table has been properly configured; see the EMM-E6 hardware manual and/or the Trap Table chapter in the SPMA Tools Guide for more information.

You can enable and disable the following Source Address traps:

•A newSourceAddress trap is generated when a station port — one receiving packets from zero, one, or two source addresses — receives a packet from a source address that is not currently in its source address table. Information included in this trap includes the board number, port number, and source address associated with the trap. Trunk ports — those receiving packets from three or more source addresses — will not issue newSourceAddress traps.

•A sourceAddressTimeout trap is issued anytime a source address is aged out of the Source Address Table due to inactivity. The trap’s interesting information includes the board and port index, and the source address that timed out. (See Setting the Aging Time,page 6-4, for more information.)
