DELL 9.7(0.0) User Manual

Important Points to Remember

• Enable DCBx on the switch before enabling the FIP Snooping feature.
• To enable the feature on the switch, configure FIP Snooping.
• To allow FIP frames to pass through the switch on all VLANs, enable FIP snooping globally on a 

switch.

• A switch can support a maximum eight VLANs. Configure at least one FCF/bridge-to-bridge port 

mode interface for any FIP snooping-enabled VLAN.

• You can configure multiple FCF-trusted interfaces in a VLAN.
• When you disable FIP snooping:

– ACLs are not installed, FIP and FCoE traffic is not blocked, and FIP packets are not processed.

– The existing per-VLAN and FIP snooping configuration is stored. The configuration is re-applied 

the next time you enable the FIP snooping feature.

• You must apply the CAM-ACL space for the FCoE region before enabling the FIP-Snooping feature. If 

you do not apply CAM-ACL space, the following error message is displayed:
Dell(conf)#feature fip-snooping

% Error: Cannot enable fip snooping. CAM Region not allocated for Fcoe.

Dell(conf)#

NOTE: Manually add the CAM-ACL space to the FCoE region as it is not applied by default.

To support FIP-Snooping and set CAM-ACL in the Z9500 switch, usecam-acl l2acl 4 ipv4acl 4
