Trap Selection 5-27
Managing Ethernet MicroLAN Modules
Source Address Traps
The Ethernet MicroLAN module can issue several different traps in response to changes
in a port’s Source Address Table:
A newSourceAddress trap is generated when a station port – one receiving packets from
no source addresses, or from 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 module 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
module and port index, and the source address that timed out.
PortTypeChanged traps are issued when a port’s topology status changes from station to
trunk, or vice versa. The interesting information includes the module and port index, and
the port’s new topology status.
A lockStatusChanged trap is generated when the ports in the hub are locked or unlocked
using the Lock/Unlock Ports option on the Repeater menus; the interesting information is
the new lock status.
PortSecurityViolation and portViolationReset traps are sent in response to changes
related to port locking: if ports are locked, the portSecurityViolation trap indicates that a
new source address has attempted access on one of the ports, and the ports are being shut
down in response; the interesting information is the module and port index, and the
violating address. PortViolationReset traps are sent when management intervention has
re-enabled a port or ports previously disabled in response to a port security violation; the
interesting information is module and port index.
Configuring Traps
The current status (enabled or disabled) for Link State, Segmentation, and Source Address
traps will always be displayed in the port-level Trap Selection window. The repeater- and
board-level windows will display current settings if they are uniform; where settings are
not uniform at the selected level, the corresponding check box will be gray.
When you configure traps, keep in mind the hierarchy of levels at which you are setting
traps; for the Ethernet MicroLAN module, traps set at the repeater or board level will
override current port-level settings for all ports on that repeater channel.
NOTE
Some older repeater devices, and devices with older versions of firmware may include a
slightly different definition of station and trunk status: station ports are defined as those
receiving packets from zero or one source addresses; trunk ports are defined as those
receiving packets from two or more source addresses. If you have any questions about
whether your device or firmware version falls into this older category, or if you would like
information about upgrading your device firmware, contact the Enterasys Global Call
Center.
