High Availability for WCCPv2

WCCPv2 supports stateful restarts and stateful switchovers. A stateful restart occurs when the WCCPv2
process fails and is restarted. A stateful switchover occurs when the active supervisor switches to the
standby supervisor. Cisco NX-OS applies the running configuration after a switchover.

Virtualization Support for WCCPv2

WCCPv2 supports Virtual Routing and Forwarding instances (VRFs). VRFs exist within virtual device
contexts (VDCs). By default, Cisco NX-OS places you in the default VDC and default VRF unless you
specifically configure another VDC and VRF.
WCCP redirection happens within a VRF. The WCCP cache engine must be configured such that the
forward and return traffic to and from the cache engine happens from interfaces that are a part of the
same VRF.
The VRF used for WCCP on an interface should match the VRF configured on that interface.
If you change the VRF membership of an interface, Cisco NX-OS removes all layer 3 configuration,
including WCCPv2.
For more information, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration
Guide, Release 4.x. and see

Chapter 14, "Configuring Layer 3 Virtualization."
You must globally enable the WCCPv2 feature (see the
page 5-7).
You can only configure WCCPv2 on Layer 3 or VLAN interfaces (see the Cisco Nexus 7000 Series
NX-OS Interfaces Configuration Guide, Release 4.x).
