Configuring Security on a Single Port
To set or change the security configuration for a single port on the hub
(twisted-pair or AUI), enter
SE and the port’s ID; for example, SE 4. The port’s
current security configuration is displayed, followed by a prompt to change
the configuration or not.
If you choose to change the configuration, you are then prompted for the
following parameters (defined on the previous page):
■ Address selection method, or authorized MAC address
■ You are first prompted if you want to change the address selection method
or the authorized address. Press [Enter] or enter N to retain the current
value. Enter Y to change the value and you are prompted to select one of
the following methods:
– learn address Continuously (enter C)
– use First address heard (enter F)
– Assign an address (enter A)
– port security Off (enter O)
■ Send alarm when intruder detected
■ Eavesdrop prevention
Note To enable security on a port, at least one of the parameters, Send Alarm or
Eavesdrop Prevention, must be set to ON.
Configuring Security on All Twisted-Pair Ports
To set or change the security configuration for all the twisted-pair ports
together, enter
SE ALL. This method is most useful when you are using the
same security configuration for all the twisted-pair ports, either at initial setup
or when you want to change the configuration for all the ports. You are
prompted whether to continue this process or not. If you choose to continue,
you are then prompted for:
■ Address selection method:
If you select First heard for all ports (F), learn continuously for all ports (C), or
security Off for all ports (O), the setting you select will be applied to all the
twisted-pair ports. If you enter F, the authorized address for each of the
twisted-pair ports will be the source address in the first packet received
from the attached device. If you enter C, each of the twisted-pair ports will
continuously update the authorized address when the attached devices
change. If you enter O, the security will be turned off for all the twisted-
