How does Cisco WCCP work?

WCCP is used between a Cisco router and a proxy server to communicate. The proxy server will tell the router that it is “alive” and ready to serve webpages. It’s also used as a “hello” message so the router knows when the proxy is down. The router is called the WCCP server and the proxy is called the WCCP client.

What is WCCP bypass?

Bypassed requests are unchanged by the ARM; they retain their client source IP address. With WCCP v2, you can exclude certain router interfaces from redirection. This causes the router to exclude traffic inbound on the specified interface from all redirection rules.

What is WCCP in networking?

The Web Cache Communication Protocol (WCCP) is a Cisco-developed content-routing technology that intercepts IP packets and redirects those packets to a destination other than that specified in the IP packet.

What does WCCP stand for?

Communication
Web Cache Communication Protocol (WCCP) is a Cisco-developed content-routing protocol that provides a mechanism to redirect traffic flows in real-time.

How do I configure WCCP?

Understanding the configuration of WCCP

Step1: Configure WCCP Version 2.
Step2: Specify the IP Address of WSA in an ACL.
Step3: Specify which traffic needs to be redirected to WSA using an ACL.
Step4: Configure WCCP Service IP and combine all the parameters.
Step5: Apply WCCP on the interface of the Router.

What is Cisco ITD?

Introduction. Cisco® Intelligent Traffic Director (ITD) is a multiterabit Layer 4 load-balancing, traffic steering, and clustering solution on the Cisco Nexus® 5000, 6000, 7000, and 9000 Series Switches.

What is WCCP redirection?

WCCP. A Cisco-developed content-routing protocol that provides a mechanism to redirect traffic flows in real-time. It has built-in load balancing, scaling, fault tolerance, and service-assurance (failsafe) mechanisms. WCCP supports the redirection of any TCP.

What port is Webcache?

By default, Web Cache listens with the HTTP protocol on port 7777 and HTTPS on port 4443. You must change these to listen on HTTP port 80 and HTTPS port 443 on the webcachehostname or the midtierhostname .

How does policy based routing work?

Policy-based routing (PBR) is a technique that forwards and routes data packets based on policies or filters. The goal of PBR is to make the network as agile as possible. By defining routing behavior based on application attributes, PBR provides flexible, granular traffic-handling capabilities for forwarding packets.

What is Cisco IP Wccp?

What is Wccp in FortiGate?

WCCP stands for “Web Cache Coordinator Protocol”. The idea is to transparently redirect user traffic to a cache (that is: no explicit web proxy configured on client web browser). Client traffic going through the FortiGate is intercepted and redirected to a web proxy.

What is ITD in Nexus?

What is the web cache communication protocol ( WCCP )?

Web Cache Communications Protocol (WCCP) The Web Cache Communication Protocol (WCCP), developed by Cisco Systems, specifies interactions between one or more routers (or Layer 3 switches) and one or more web-caches.

Which is version of WCCP does Cisco use?

WCCP enables you to integrate content engines into your network infrastructure. Cisco IOS Release 12.1 and later releases allow the use of either WCCP Version 1 (WCCPv1) or Version 2 (WCCPv2). The tasks in this document assume that you have already configured content engines on your network.

Do you need an IP address to use WCCP?

To use WCCP, IP must be configured on the interface connected to the Internet and another interface must be connected to the content engine. The interface connected to the content engine must be a Fast Ethernet or Gigabit Ethernet interface.

What does WCCP stand for in WAN optimization?

In this article, we’ll be going through what WCCP is, how traffic is forwarded between a WAN optimizer and a router via WCCP, and how to configure WCCP. WCCP stands for Web Cache Communication Protocol. Unfortunately, the name WCCP does not really give you a hint as to what it does, why it needs to do it, or how it does what it does.
