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.

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 ipv6acl 0 ipv4qos

The following sections describe how to enable FCoE transit.

NOTE: FCoE transit is disabled by default. To enable this feature, you must follow the

As soon as you enable the FCoE transit 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.
