922 FIP Snooping Commands
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.
FIP snooping requires all FIP ports be configured with an untagged VLAN to
establish the FIP sessions. Routing cannot be enabled on the VLAN. To
disable routing on a VLAN, use the "no ip address" command in interface
VLAN mode.
Example
The following example enables the FIP snooping feature.
s1(config)#feature fip-snooping
fip-snooping enable
Use the fip-snooping command in VLAN Configuration mode to enable
snooping of FIP packets on the configured VLANs. FIP snooping is disabled
on VLANs by default.
Use the no form of the command to return the mode to the default (off).
Syntax
fip-snooping enable
no fip-snooping enable
Default Configuration
The default mode is off (FIP snooping is disabled.)
Command Mode
VLAN Configuration
User Guidelines
Priority Flow Control (PFC) must be operationally enabled before FIP
snooping can operate on an interface. VLAN tagging must be enabled on the
interface in order to carry the dot1p value through the network.
