Cisco Cisco ASA 5550 Adaptive Security Appliance 릴리즈 노트

Please note the following operational limitations:

Stateful Failover with Phone Proxy—When using Stateful Failover with phone proxy, information 
is not passed to the standby unit; when the active unit goes down, the call fails, media stops flowing, 
and the call must be re-established.

No .NET over Clientless sessions—Clientless sessions do not support .NET framework applications 
(CSCsv29942).

When using Clientless SSL VPN Post-SSO parameters for the Citrix Web interface bookmark, 
Single-Signon (SSO) works but the Citrix portal is missing the Reconnect and Disconnect buttons. 
Only the Log Off button shows up. When not using SSO over Clientless, all three buttons show up 
correctly.

Workaround: Use the Cisco HTTP-POST plugin to provide single signon and correct Citrix portal 
behavior.

The adaptive security appliance does not support phone proxy and CIPC for remote access.

Use the show version command to verify the software version of your adaptive security appliance.
