Chapter 5 Configuring WCCPv2
Configuring WCCPv2
• A WCCPv2 service group supports up to 32 routers and 32 cache engines.
• All cache engines in a cluster must include all routers servicing the cluster in its configuration. If a
cache engine within a cluster does not include one or more of the routers in its configuration, the
service group will detect the inconsistency and the cache engine will not be allowed to operate
within the service group.
• The cache engine cannot be on the same SVI with a redirect out statement.
• WCCPv2 works with IPv4 networks only.
• Do not configure policy-based routing and WCCPv2 on the same interface.
• Cisco NX-OS removes all Layer 3 configuration on an interface when you change the VDC,
interface VRF membership, port channel membership, or the port mode to Layer 2.
• Wildcard masks are not supported for the WCCPv2 redirect list.
• Cisco NX-OS does not support WCCPv2 on tunnel interfaces.
• WCCP requires the client, server, and WCCP client to be on separate interfaces. If you migrate a
topology from a Cisco Catalyst 6500 Series switch deployment, it might not be supported.
Configuring WCCPv2
To configure WCCPv2, follow these steps:
Step 1 Enable the WCCPv2 feature. See the “Enabling the WCCPv2 Feature” section on page 5-7.
Step 2 Configure a service group. See the “Configuring a WCCPv2 Service Group” section on page 5-8.
Step 3 Apply WCCPv2 redirection to an interface. See the “Applying WCCPv2 Redirection to an Interface”
section on page 5-9.
This section includes the following topics:
• Enabling the WCCPv2 Feature, page 5-7
• Configuring a WCCPv2 Service Group, page 5-8
• Applying WCCPv2 Redirection to an Interface, page 5-9
• Configuring WCCPv2 in a VRF, page 5-10
Note If you are familiar with the Cisco IOS CLI, be aware that the Cisco NX-OS commands for this feature
might differ from the Cisco IOS commands that you would use.
Enabling the WCCPv2 Feature
You must enable the WCCPv2 feature before you can configure WCCPv2.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).
