Tip To save your changes and apply them later, click Submit. When you are ready
to implement the changes, select System Configuration > Service Control
and click Restart.
Note Restarting the service clears the Logged-in User Report, refreshes the
Max Sessions counter, and temporarily interrupts all Cisco Secure
ACS services.
Setting a Session-Based WEP Key Timeout
You can set a timeout value for the session-based WEP key. When the timeout
value elapses, the server issues a new dynamic WEP key for authenticated client
devices.
Note If you enable TKIP (WEP key hashing) on the access point, you do not need
to set up a session-based WEP key timeout. You can use both TKIP and a
session key timeout, but these features provide redundant protection.
You should consider several factors when determining the best session key
timeout value for your wireless network. Consult Product Bulletin 1515: Cisco
Wireless LAN Security Bulletin for guidelines on selecting timeout values. Use

Follow these steps to set a timeout value for session-based WEP keys:
Step 1 On the ACS main menu, click Group Setup.
Step 2 In the Group drop-down menu, select the group for which you want to modify the
WEP key/session timeout. The Default group is usually the group you need to
modify.
Step 3 Click Edit Settings.
