Table of Contents

The following sections describe how to configure the FIP snooping feature on a switch that functions as a

FIP snooping bridge so that it can perform the following functions:

Allocate CAM resources for FCoE (optional in FTOS version 9.1.(0.0)).

Perform FIP snooping (allowing and parsing FIP frames) globally on all VLANs or on a per-VLAN

Set the FCoE MAC address prefix (FC-MAP) value used by an FCF to assign a MAC address to an

FCoE end-device (server ENode or storage device) after a server successfully logs in. The FC-MAP

value is used in the ACLs installed in bridge-to-bridge links on the switch.

Set the FCF or Bridge-to-Bridge Port modes to provide additional port security on ports that are

directly connected to an FCF and have links to other FIP snooping bridges.

Check FIP snooping-enabled VLANs to ensure that they are operationally active.

Process FIP VLAN discovery requests and responses, advertisements, solicitations, FLOGI/FDISC

requests and responses, FLOGO requests and responses, keep-alive packets, and clear virtual-link

FIP Snooping in a Switch Stack

FIP snooping supports switch stacking as follows:

A switch stack configuration is synchronized with the standby stack unit.

Dynamic population of the FCoE database (ENode, Session, and FCF tables) is synchronized with the

standby stack unit. The FCoE database is maintained by snooping FIP keep-alive messages.

In case of a failover, the new master switch starts the required timers for the FCoE database tables.

Timers run only on the master stack unit.

The configuration of FIP snooping consists of the following tasks:

1. Enable the FIP snooping feature on a switch to maintain FIP snooping information on the switch.

2. Enable FIP snooping on all VLANs (globally) or individual VLANs on a FIP snooping bridge.

3. Configure the FC-Map value applied globally by the switch on all VLANs or an individual VLAN.

4. Configure FCoE-Trusted mode for a FIP snooping bridge-to-bridge link.

5. Configure FCF mode for a FIP snooping bridge-to-FCF link.
