What Is Fip Snooping - Dell PowerConnect 8024 User Configuration Manual

What Is FIP Snooping?

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 distinguish discovery, initialization, and
maintenance traffic from other FCoE traffic.FIP frames are standard
Ethernet size (1518 Byte 802.1q frame), whereas FCoE frames are a
maximum of 2240 bytes.
FIP snooping 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.
FIP snooping allows for:
• Auto-configuration of Ethernet ACLs based on information in the
Ethernet headers of FIP frames.
• Emulation of FC point-to-point links within the DCB Ethernet network.
• Enhanced FCoE security/robustness by preventing FCoE MAC spoofing.
The role of FIP snooping-enabled ports on the switch falls under one of the
following types:
• Perimeter or Edge port (connected directly to a Fibre Channel end node or
ENode).
• Fibre Channel forwarder (FCF) facing port (that receives traffic from
FCFs targeted to the ENodes).
NOTE:
The PowerConnect 8024/8024F FIP Snooping Bridge feature supports the
configuration of the perimeter port role and FCF-facing port roles and is intended
for use only at the edge of the switched network.
The default port role in an FCoE-enabled VLAN is as a perimeter port. FCF-
facing ports are configured by the user.
