Trap Selection 5-23
Managing Ethernet MicroLAN Switches
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 Switch, traps set at the repeater or board
level will override current port-level settings for all ports on that repeater
channel.
To enable or disable the above-described traps:
1. Open the appropriate Trap Selection window.
2. Click on the check box next to the desired trap: Link State, Segmentation,
or Source Address.
An empty check box indicates that the corresponding trap is disabled;
A checked box indicates that the corresponding trap is enabled;
A check box that remains gray indicates that the associated trap will not be set
(to either enabled or disabled), and the current mode of mixed settings at the
port level will be maintained.
TIP
When you are setting repeater- or module-level traps, we recommend that you leave the
gray “No SET” status untouched (especially for Source Addressing Traps) unless you are
sure
you want to override port-level settings. With no incoming traps to inform you of a
port security violation, you may have ports that are disabled on your device for no obvious
reason.
