41 FIP Snooping Commands NOTE: Fiber Channel over Ethernet (FCoE) commands are only supported on the PC8024 and PC8024F switches. CLI commands and Dell OpenManage Switch Administrator pages are not available for other switch models. The FCoE Initialization Protocol (FIP) is used to perform the functions of FC_BB_E device discovery, initialization and maintenance. FIP uses a separate EtherType from FCoE to enable the distinction of discovery, initialization, and maintenance traffic from other FCoE traffic. FIP frames (with one exception) are the standard Ethernet size (1518 Byte 802.1q frame) whereas FCoE frames are a maximum of 2240 bytes. This document describes FIP snooping, which is a frame inspection method used by FIP Snooping Bridges to monitor FIP frames and apply policies based upon the L2 header information in those frames, following recommendations in Annex C of FC_BB_5 Rev 2.00. This allows for: 1 Auto-configuration of Ethernet ACLs based on information in the Ethernet headers of FIP frames. 2 Emulation of FC point-to-point links within the DCB Ethernet network. 3 Enhanced FCoE security/robustness by preventing FCoE MAC spoofing. The FIP Snooping Bridge solution in PowerConnect Dell 5.1 supports configuration-only of perimeter port role and FCF-facing port roles and is only intended for use at the edge of the switched network. The role of FIP Snooping-enabled ports on the switch falls under one of the following types: 1 Perimeter or Edge port (connected directly to ENode). 2 FCF facing port (that receives traffic from FCFs targeted to the ENodes). The default port role in an FCoE enabled VLAN is as a perimeter port. FCF facing ports must be configured by the user.
