 Nexus 5600/6000 L2 Unicast Forwarding
 Forwarding Manager(FWM) is responsible for programming hardware in
Nexus 5600/6000 for forwarding
 Hardware MAC address table referred to as Station Management
Table(STM)
 L2 forwarding highlights
 Check if VLAN is allowed on ingress interface(STP state)
 For a new MAC, add source address to STM table with Vlan info
 STM table is synchronized across all ASICs
 If destination MAC is a hit against “myipr” table, packets are sent to L3
pipeline. Otherwise L2 forwarding
