Port Configuration 4-9
To set a Locally Administered Address, take these
steps in the Locally Admin. field:
1 Enter address in hexadecimal.
This should be between 400000 000000 and
7FFFFF FFFFFF.
2 Press [OK].
3 Reset the Switch 2000 TR.
NOTE:The Locally Administered address will not be
valid until the Switch 2000 TR is reset. Refer to
“Resetting the Switch 2000 TR in Chapter 3 for
instructions on resetting.
To reverse the Locally Administered address and revert
to the resident MAC address enter all zeros and reset
the Switch 2000 TR.
Setting Broadcast Storm Control
The Switch 2000 TR automatically creates an alarm
on each of its ports for monitoring broadcast levels if
an alarm is set. This field allows you to set broadcast
threshold levels on each port. You can also set the
threshold action per port. Thresholds are calculated
using a moving 20 second window.
Rising Threshold%
The Rising threshold percentage setting determines
the amount of broadcast traffic that will be allowed
before an alarm is sent. The default setting is 60%.
Falling Threshold%
The Falling threshold percentage setting determines
the level at which the broadcast threshold will be
reset. This setting prevents the rising threshold events
from being triggered continuously. Events are only
enabled after the Falling Threshold is met. The default
setting is 50%.
1 Set the threshold fields by entering a number
between 0 and 99.
2 Press [Return].
Rising Action
Use this field to set alarm action for the rising thresh-
old. You have the following choices:
■ None—No action
■ Event—Event generated for SNMP
■ Blip—Port disabled, then enabled after 5 seconds
■ Event+blip—Port disabled, then enabled after 5
seconds and event generated
Falling Action
Use this field to set the action for the falling thresh-
old. Choices:
■ None—No action. Default
■ Event—Event generated
1 Set the action fields by toggling [Space Bar] to the
desired threshold actions.
2 Press [Return].
