feature fip-snooping
The
feature fip-snooping
command is used in the Global Configuration mode in order to globally enable
Fibre Channel over Ethernet Initialization Protocol (FIP) snooping on the switch. Any received FIP frames
are forw
arded or flooded using the normal multicast rules if FIP snooping is disabled.
When it is enabled, however, FC-BB-5 Annex D ACLs will be installed on the switch and the FIP frames
will be snooped. Unless and until a port is operationally enabled for PFC, then FIP snooping will not
permit FIP or Fibre Channel over Ethernet (FCoE) frames to be forwarded over that port. And, in order to
carry dot1p values through the network, VLAN tagging must be enabled on the interface.
The
no
command is used to reset the settings back to the default values and to globally disable FIP
snooping. Any received FIP frames will be
forwarded or flooded using the normal multicast rules when
FIP snooping is disabled. In addition, no other FIP snooping commands will be available until the FIP
snooping feature has been enabled.
feature fip-snooping
no feature fip-snooping
Parameters
None
Default
The default is Disabled.
Command Mode
Global Config
Example
The following example of the command enables the FIP snooping feature.
s1(config)#feature fip-snooping
The following example of the
no
command disables the FIP snooping feature.
s1(config)#no feature fip-snooping

fip-snooping enable
The
fip-snooping enable
command is used in the VLAN Configuration mode in order to enable the
snooping of FIP packets on the configured VLANs. (By default, FIP snooping is disabled on VLANs.)
Before FIP snooping can operate on an interface, Priority Flow Control (PFC) must be operationally
enabled. Meanwhile, VLAN tagging has to be enabled on the interface in order for the dot1p value to be
carried through the network.
This command may only be input after FIP snooping has been enabled using the
command. Otherwise, the command will not appear in the CLI syntax tree.
The
no
command resets the mode to the default setting (off).
