Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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
