About packet-mode optimization rules
When you create a fixed-target packet-mode optimization rule, you define the inner channel characteristics using these controls: source and destination subnet, source and destination port (or port label), and DSCP marking.
Packet-mode optimization supports these topologies:
• Physical in-path
• Virtual in-path
– WCCP/PBR or TCPv4, UDPv4
– PBR for TCPv6, UDPv6
• Master and backup
Packet-mode optimization does not support these topologies:
• Out-of-path
• Serial cluster
• Interceptor integration
