Fcoe Example Configuration - Lenovo Flex System Fabric CN4093 Application Manual

FCoE Example Configuration

1. Configure FCoE ports as trunk ports and add them to FCoE Vlan for FCoE traffic
2. Turn CEE on.
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:

The following example collects the various components from previous sections of
this chapter.

In Figure 33 on page 288, 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.
and Native Vlan 1 for FIP negotiation:
CN4093(config)# interface port INTA1
CN4093(config­if)# switchport mode trunk (Enable VLAN tagging)
CN4093(config­if)# switchport trunk allowed vlan 1,1002 (Add VLANs)
CN4093(config­if)# exit
CN4093(config)# cee enable
Note: Turning CEE on will automatically change some 802.1p QoS and 802.3x
standard flow control settings and menus (see
page 265).
CN4093(config)# fcoe fips enable
CN4093(config)# no fcoe fips port EXT1­EXT20 enable
CN4093(config)# fcoe fips port INTA1 enable
CN4093(config)# fcoe fips port INTA1 fcf­mode off(Set as ENode connection)
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.
