Configuration notes
Dell EMC PowerSwitch S4148U-ON:
The total errors count in the show interface fibrechannel command output displays incorrect values during FC port flaps, IOM
reboot, or port conversion from ETH to FC, followed by bringing up of the FC port.
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 traffic in the Ethernet networks.
FIP and FCoE provide FC emulation over Ethernet links.
An Ethernet switch configured 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
NOTE: OS10 supports multiple ENodes in F_Port mode.
Using the discovered information, the switch installs ACL entries that provide security and point-to-point link emulation.
Configure FIP snooping
1. Enable FIP snooping 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. 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.
4. Add an FC map to the VLAN with the fip-snooping fc-map fc-map command.
