The Web Cache Communication Protocol (WCCP) was at first planned as a part of IOS whose reason for existing was to catch HTTP movement crossing a switch and divert that activity to a nearby store with the point of diminishing access times to sites and saving wide zone data transfer capacity. Normally the bundles are diverted from their goal web server on the Internet to a substance motor that is neighborhood to the customer. In some WCCP arrangement situations, redirection of movement may likewise be required from the web server to the customer. WCCP empowers you to incorporate substance motors into your system framework. With the presentation of WCCPv2 the extent of the convention enlarged to incorporate movement sorts other than HTTP enabling the convention to be utilized as a more broad block attempt system. In WCCPv2 customers determine the idea of the movement to be blocked and sent to outer gadgets which are then in a position to give administrations, in view of the activity sort, for example, WAN advancement and application speeding up.

Cisco IOS Release 12.1 and later discharges permit the utilization of either WCCP Version 1 (WCCPv1) or Version 2 (WCCPv2).

WCCP VRF Support

The WCCP VRF Support include upgrades the current WCCPv2 convention by executing support for virtual steering and sending (VRF).

The WCCP VRF Support include permits benefit gatherings to be designed on a for each VRF premise notwithstanding those characterized universally.

Alongside the administration identifier, the VRF of WCCP convention bundles touching base at the switch is utilized to relate reserve motors with an arranged administration gathering.

The interface on which redirection is connected, the interface which is associated with store motor, and the interface on which the bundle would have left in the event that it had not been diverted must be in the same VRF.

In Cisco IOS Release 12.2(33)SRE, this element is bolstered just on Cisco 7200 NPE-G2 and Cisco 7304-NPE-G100 switches.

Configuring WCCP

Until the point that you design a WCCP benefit utilizing the ip wccp {web-reserve | benefit number} worldwide arrangement summon, WCCP is impaired on the switch. The principal utilization of a type of the ip wccp order empowers WCCP. As a matter of course WCCPv2 is utilized for administrations, however you can utilize WCCPv1 usefulness. To change the running variant of WCCP from Version 2 to Version 1, or to come back to WCCPv2 after an underlying change, utilize the ip wccp rendition order in worldwide design mode.

On the off chance that a capacity is not permitted in WCCPv1, a mistake incite will be printed to the screen. For instance, if WCCPv1 is running on the switch and you endeavor to arrange a dynamic administration, the accompanying message will be shown: "WCCP V1 just backings the web-store benefit." The show ip wccp EXEC order will show the WCCP convention variant number that is as of now running on your switch.

Utilizing the ip wccp web-reserve secret word order, you can set a watchword for a switch and the substance motors in an administration gathering. MD5 secret key security requires that every switch and substance motor that needs to join an administration amass be arranged with the administration assemble watchword. The secret key can comprise of up to eight characters. Each substance motor or switch in the administration gathering will confirm the security part in a got WCCP parcel quickly subsequent to approving the WCCP message header. Bundles coming up short verification will be disposed of.
