Question:
ASA not redirecting traffic to WSA after proxy restart or temporary communication interruption between WSA and ASA
Environment:
- Cisco Web Security Appliance (WSA)
- ASA versions below 7.2(4.35)
- WCCP
The ASA prior to version 7.2(4.35) is affected by Cisco defect CSCsy82260. This bug causes the ASA to stop redirecting traffic after the WSA proxy has a restart.
This is resolved in ASA OS versions 7.2(4.35), 8.0(4.34), 8.1(2.25), and 8.2(1.10)
Note:
If upgrading ASA is not possible, then an immediate workaround is to remove the WCCP interface commands from the ASA and re-apply them.
Command to remove WCCP interface configuration: no wccp interface <Interface-name> <service-ID> redirect in
Command to re-add WCCP interface configuration: wccp interface <Interface-name> <service-ID> redirect in
