• Sessions between ENodes and FCFs
Using the discovered information, the switch installs ACL entries that provide security and point-to-point link emulation.
Fibre Channel over Ethernet
Fibre Channel over Ethernet (FCoE) encapsulates Fibre channel frames over Ethernet networks.
FCoE Initialization protocol (FIP) establishes Fibre channel connectivity with Ethernet ports.
FIP snooping bridge (FSB) implements security characteristics to admit valid FCoE trac in the Ethernet networks.
FIP and FCoE provide FC emulation over Ethernet links.
An Ethernet switch congured to operate in FSB mode snoops FIP packets on FCoE enabled VLANs and discovers the following
information:
• End nodes (ENodes)
• Fibre channel forwarder (FCF)
• Connections between ENodes and FCFs
• Sessions between ENodes and FCFs
Using the discovered information, the switch installs ACL entries that provide security and point-to-point link emulation.
Congure FIP snooping
1 Enable the FIP snooping feature globally using the feature fip-snooping command in CONFIGURATION mode.
2 Before applying FIP snooping to a VLAN, ensure that the VLAN already contains Ethernet or LAG members that are enabled with FCF
port mode. You can enable FCF mode on an Ethernet or port-channel using the fip-snooping port-mode fcf command in
INTERFACE mode.
3 Enable FIP snooping on the VLAN using the fip-snooping enable command in VLAN INTERFACE mode. You can apply FIP
snooping on a maximum of 12 VLANs.
