Chapter 64 Configuring WCCP Version 2 Services Verifying and Monitoring WCCP Configuration Settings

Setting a Password for a Router and Cache Engines

MD5 password security requires that each content engine and Catalyst 4500 series switch that wants to
join a service group be configured with the service group password. The password can consist of up to
seven characters. Each content engine or Catalyst 4500 series switch in the service group authenticates
the security component in a received WCCP packet immediately after validating the WCCP message
header. Packets failing authentication are discarded.
To configure an MD5 password for use by the Catalyst 4500 series switch in WCCP communications,
perform this task:
Verifying and Monitoring WCCP Configuration Settings
To verify and monitor the configuration settings for WCCP , use the follo wing commands in EXEC mode:
Command Purpose
Switch(config)# ip wccp web-cache password password Sets an MD5 password on the Catalyst
4500 series switch.
Command Purpose
Switch# show ip wccp [web-cache | service-number]Displays global information related to WCCP, including
the protocol version currently running, the number of
content engines in the routers service group, which
content engine group is allowed to connect to the router,
and which access list is being used.
Switch# show ip wccp {web-cache | service-number} detail Queries the router for information on which content
engines of a specific service group the router has
detected. The information can be displayed for either
the web cache service or the specified dynamic service.
Switch# show ip interface Displays status about whether any ip wccp redirection
commands are configured on a client interface. For
example, “Web Cache Redirect is enabled / disabled.”
Switch# show ip wccp {web-cache | service-number} view Displays which devices in a particular service group
have been detected and which content engines are
having trouble becoming visible to all other switches to
which the current switch is connected.
The view keyword indicates a list of addresses of the
service group. The information can be displayed for
either the web cache service or the specified dynamic
service.
For further troubleshooting information, use the
show ip wccp {web-cache | service number} service
command.
