Configuring the Multicast Best Effort Mode for a SPAN Session
You can configure the multicast best effort mode for any SPAN session. By default, SPAN replication occurs
on both the ingress and egress modules. When you enable the multicast best effort mode, SPAN replication
occurs only on the ingress module for multicast traffic or on the egress module for packets that egress out of
Layer 3 interfaces (that is, on the egress module, packets that egress out of Layer 2 interfaces are not replicated
for SPAN).
