Security 7-15
■
The trap host password is included in the trap messages and will help the
trap host station to identify whether a received trap host message came from
its own domain or not.
Trap Host Messages
The following message types can be distinguished:
■
Call boot trap messages
■
Authentication failure messages
■
Link up or down messages
Call Boot Trap Messages
A Call boot trap message can occur in one of the following situations:
■
Access Point is reset
■
Power down
■
Access Point configuration has been changed
Authentication Failure Messages
This message type is sent to the LAN administrator station once a wrong
password has been entered on a (mobile) station. However, the Access Point
itself does not respond, a time out error occurs.
Link Up or Down Messages
This type of message can be used to signal a problem with link integrity. If an
ethernet link is broken, a Trap message “link down” is sent. As a result of this
message, the WL510 Access Point disables it’s wireless interface to allow client
stations to disconnect from the WL510 Access Point and re-connect to another
Access Point that provides a correct link to the Ethernet network. Once the link
is restored, the original WL510 Access Point will send a “link up” message. The
original Access Point can be used again.
Advanced Security Maintenance
Maintaining Access Control Tables
It is best to create a single access control table and store it on the harddisk of the
LAN administrator station and/or share it with other LAN administrator stations.
You are advised to use only one table for all Access Points.
For more information refer to “Creating/Editing an Access Control Table” on
page 7-4.
Maintaining WEP Encryption Keys
The WEP Encryption functionality allows the wireless system to support up to
four different keys simultaneously. This is in accordance with the 802.11
standard, which defines four so-called “default keys”.
