Configuring Source Address Traps 6-7
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.
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.)
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.
