Wccp - EdgeWave iPrism Web Security Administration Manual

iPrism
The community string is now available.
Note: The same community string must be used in both the MIB browser and
the iPrism.

WCCP

iPrism supports the WCCP protocol (versions 1 and 2). WCCP provides fault tolerance by automatic
detection and rerouting to eliminate network downtime in the event that iPrism is turned off,
disconnected, or a system failure occurs.
For WCCP v2 specifically, iPrism supports the following:
• Specification of up to 32 routers (IP addresses).
• Optional specification of a service group password if desired.
Important: WCCP v2 does not support the use of a multicast IP address for a
group of routers. Users must specify each of the router addresses they want to
use. Validation exists to prevent users from adding a multicast IP address; i.e.,
anything within the range of 224.0.0.0 to 239.255.255.255.
The configuration is straightforward, and involves deploying iPrism V3.200 or greater and a router
which supports WCCP. When the client workstation generates traffic outbound to web servers on
the Internet, the router detects that it is HTTP traffic (TCP port 80) and diverts that traffic to iPrism
using a GRE tunnel. iPrism then makes the request to the server on behalf of the client, and
responds directly to the client. However, from a client perspective, the response appears to come
directly from the origin server, so the client does not even know it is communicating with iPrism.
Note: iPrism can be placed on either side of the router.
