User Guidelines
When FIP snooping is disabled, received FIP frames are forwarded or flooded
using the normal multicast rules.
When FIP snooping is enabled, FC-BB-5 Annex D ACLs are installed on the
switch and FIP frames are snooped. FIP snooping will not allow FIP or Fiber
Channel over Ethernet (FCoE)
frames to be forwarded over a port until the
port is operationally enabled for PFC. VLAN tagging must be enabled on the
interface in order to carry the dot1p values through the network.
