Does a WAAS network module require WCCP to be configured?

[jkeeffe]

When configuring an NME-WAE-522 as an Edge-WAE, since this is installed inside a 3845 router, do I need to configure WCCP on the 3845 and the NME? Or because the NME is physically inside the router is it considered 'inline'?

Hello Jim,

WCCP Support

Web Cache Communications Protocol (WCCP) is a free software feature in Cisco IOS Software that runs on Cisco routers, including the Cisco 1800, 2600, 2800, 3600, 3700, 3800, and 7000 Series, and Cisco switches such as the Cisco Catalyst® 4500, 4900, and 6500 Series.

WCCP can provide fault-tolerance

A technology called Web Cache Communication Protocol Version 2 (WCCPv2) facilitates synchronization of Cisco IOS Software features and Cisco WAAS services. WCCP redirects traffic from the router to the WAAS module and back. If the WAAS module suffers an impairment, WCCP-a stateful protocol-bypasses the module and passes traffic directly to the WAN to preserve connectivity and user sessions.

It looks like that WCCP can provide some benefits with the WAAS module and the ISR router.

Hope to help
