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 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.
