Syntax Description This command has no arguments or keywo rds.
Defaults WCCP services are not enabled on the router.
Command Modes Global configuratio n (config)
Usage Guidelines W ith the ip wccp check services all command, WCCP can be configured to check all configured
services for a match and perform redirection for those services if appropriate. The caches to which
packets are redirected can be controlled by a redirect ACL access control list (ACL) as well as by the
priority value of the service.
It is possible to configure an interface with more than one WCCP serv ice. When more than one WCCP
service is configured on an interface, the precedence of a service depends on the relative priority of the
service compared to the priority of the other configured services. Each WCCP service has a priority
value as part of its definition.
If no WCCP services are configured with a redirect ACL, the services are considered in priority order
until a service is found which matches the IP packet. If no services match the packet, the packet is not
redirected. If a service matches the packet and the service has a redirect ACL configured, then the IP
packet will be checked against the ACL. If the packet is rejected by the ACL, the packet will not be
passed down to lower priority services unless the ip wccp check services all command is configure d.
When the ip wccp check services all command is configured, WCCP will continue to attempt to match
the packet against any remaining lower priority services configured on the interface.
Note The priority of a WCCP serv ice group is de termined by t he web cache appliance. The priority of a WCCP
service group cannot be configu red via Cisco IOS software .
Note The ip wccp check services all command is a global WCCP command that applies to all services and is
not associated with a single service.
Examples The following example shows how to configur e all WCCP services:
Router(config)# ip wccp check services all
