Setting Up Traps 4-25
Setting Up Traps
Traps are messages sent across the network to an
SNMP Network Manager. They alert the network
administrator to faults or changes at the Switch
device.
Your Network Manager may automatically set up
traps in the Switch Trap Table. Check the documen-
tation accompanying the network management
software.
To access the Trap Setup screen, select the SETUP
TRAPS button from the Management Setup screen
(described in
Chapter 3 ). The Trap Setup screen is
shown in Figure 4-16 .
The screen shows the following:
IP or IPX Address This field allows you to enter the
IP or IPX address of the remote network manage-
ment stations to which traps should be sent.
Community String This field allows you to enter
community strings for each remote Network Man-
ager, allowing a very simple method of authentica-
tion between the Switch and the remote Network
Manager. The text string can be of 32 characters or
less. If you want a Network Manager to receive
traps generated by the device, you must enter the
community string of the Network Manager into the
trap table. The default community string is
public .

Throttle
This field allows you to specify a throttle
delay value for each remote Network Manager.
Throttle delays are time periods placed between
packets to prevent a remote Network Manager
receiving too many traps at once. The unit of throt-
tle is one thousandth of a second. The default
value is 100, which gives a delay of one tenth of a
second between each packet transmission.
