Understanding Promiscuous Mode on Ethernet Interfaces

When promiscuous mode is enabled on a Layer 3 Ethernet interface, all packets received on the interface are sent to the central point or Services Processing Unit regardless of the destination MAC address of the packet. You can also enable promiscuous mode on chassis cluster redundant Ethernet interfaces and aggregated Ethernet interfaces. If you enable promiscuous mode on a redundant Ethernet interface, promiscuous mode is then enabled on any child physical interfaces. If you enable promiscuous mode on an aggregated Ethernet interface, promiscuous mode is then enabled on all member interfaces.
