Enabling the FIP Snooping Feature

Note: FIP Snooping is disabled by default. To enable this feature, you must follow the

As soon as you enable the FIP snooping feature on a switch-bridge, existing VLAN-specific and FIP

snooping configurations are applied. The FCoE database is populated when the switch connects to a

converged network adapter (CNA) or FCF port and compatible DCB configurations are synchronized. By

default, all FCoE and FIP frames are dropped unless specifically permitted by existing FIP

snooping-generated ACLs. You can reconfigure any of the FIP snooping settings.

If you disable FIP snooping, FIP and FCoE traffic are handled as normal Ethernet frames and no FIP

snooping ACLs are generated. The VLAN-specific and FIP snooping configuration is disabled and stored

until you re-enable FIP snooping and the configurations are re-applied.

You can enable FIP snooping globally on a switch on all VLANs or on a specified VLAN. When you

enable FIP snooping on VLANs:

FIP frames are allowed to pass through the switch on the enabled VLANs and are processed to

generate FIP snooping ACLs.

FCoE traffic is allowed on VLANs only after a successful virtual-link initialization (fabric login

FLOGI) between an ENode and an FCF. All other FCoE traffic is dropped.

You must configure at least one interface for FCF (FIP snooping bridge-bridge) mode on a FIP

snooping-enabled VLAN. You can configure multiple FCF trusted interfaces in a VLAN.

A maximum of eight VLANS are supported for FIP snooping on the switch.When enabled globally,

FIP snooping processes FIP packets in traffic only from the first eight incoming VLANs. When

enabled on a per-VLAN basis, FIP snooping is supported on up to eight VLANs.

You can configure the FC-MAP value to be applied globally by the switch on all or individual FCoE

VLANs to authorize FCoE traffic.

The configured FC-MAP value is used to check the FC-MAP value for the MAC address assigned to

ENodes in incoming FCoE frames. If the FC-MAP value does not match, FCoE frames are dropped. A

session between an ENode and an FCF is established by the switch-bridge only when the FC-MAP value

on the FCF matches the FC-MAP value on the FIP snooping bridge.
