  • Cisco Wide Area Application Services (WAAS) Appliances

Known Affected Releases

5.3(5)

Description (partial)

Symptom:
Data for connections accelerated via WAAS box, is corrupted during transfer, some examples:
-Web-sites are not loaded fully, garbage characters are displayed, HTTP access is very slow - basically, web-sites are unusable. Disabling only HTTP AO does not resolve the issue
- FTP transfer, if accelerated via WAAS, corrupts files in transit (for e.g. if you transfer via FTP some archive, archive cannot be opened anymore)

Conditions:
1. Optimization policy for affected transfer contains DRE optimization
2. One of the boxes is WAE-674, WAE-7371 or WAE-7341 and is using inline interception method. Rest of the WAAS devices are not impacted such as 294, 594, 694, 7541, 7571, 8541, SM-SRE, vWAAS and kWAAS.
