Wireless Security
If WEPKEY is set to
bits40
or
bits104
, the keys are automatically obtained
(either 40 or 104 bits). All wireless clients must support 104-bit keys, in case a
104-bit key is used.
CAUTION!
You must disable PSK WEP encryption if you want to use an option other than
PSK.
The
rekey
parameter allows you to specify Group Key Rekey options to
improve security. These options allow you to specify that a new group key (the
key that is used for communication between the access radio and a group of
clients) must be generated at regular intervals.
If
rekey
is set to
no
, then the group key is not changed. This is the default when
802.1X is enabled. If
rekey
is set to n seconds, the group key is changed after
that time period. If
rekey
is set to n kpackets, the group key is changed after
that many thousand packets.
The
ssid_index
parameter must be a valid SSID index. The default value is 1.
Example 1
/# cd radio
/radio# show arm1 dot1x
dot1x wepkey : bits104
rekey method : no
state : disabled
Example 2
/# cd radio
/radio# set arm1 dot1x wepkey bits104 rekey kpackets 1000 enabled
Additional Considerations
If 802.1X is already enabled, entering the
set dot1x
command only changes the
specified parameter.
For instance, if you have entered the following command:
set arm1 dot1x wepkey bits104 rekey kpackets 1000 enabled
The following
set dot1x
command only changes the re-key method to once
every 100 seconds, without making any other changes.
set arm1 dot1x rekey seconds 100 enabled
