FCoE Example Configuration
The following example collects the various components from previous sections of
this chapter.
Figure 34.
A Mixed Fibre Channel and FCoE Network
In Figure 34 on page 326 , a Fibre Channel network is connected to the CN4093 on
port EXT22. The FCoE ‐ enabled CN4093 is internally connected to a blade server
(ENode) through an FCoE ‐ enabled CNA on port INTA1. An internal FCF bridges
the networks.
1.
Configure FCoE ports as trunk ports and add them to FCoE VLAN for FCoE traffic
and any Native VLAN (other than the FCoE VLAN) for FIP negotiation:
2.
Turn CEE on.
Note:
Turning CEE on will automatically change some 802.1p QoS and 802.3x
standard flow control settings and menus (see “Turning CEE On or Off” on
page 302 ).
3.
Turn global FIP snooping on:
4.
Disable FIP snooping on all non ‐ FCoE external ports:
5.
Enable FIP snooping on FCoE ports, and set the desired FCF mode:
Note:
By default, FIP snooping is enabled on all ports and the FCF mode set for
automatic detection. The configuration in this step is unnecessary if default
settings have not been changed, and is shown merely as a manual configuration
example.
