Figure 38. FIP Snooping on an Core Switch
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.
● Perform FIP snooping (allowing and parsing FIP frames) globally on all VLANs or on a per-VLAN basis.
● To assign a MAC address to an FCoE end-device (server ENode or storage device) after a server successfully logs in, set
the FCoE MAC address prefix (FC-MAP) value an FCF uses. The FC-MAP value is used in the ACLs installed in bridge-to-
bridge links on the switch.
● To provide more port security on ports that are directly connected to an FCF and have links to other FIP snooping bridges,
set the FCF or Bridge-to-Bridge Port modes.
● To ensure that they are operationally active, check FIP snooping-enabled VLANs.
● 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 messages.
