CN4093 Application Guide for N/OS 8.4
Fibre Channel configuration requires that at least one pair of Omni Ports be set to
Fibre Channel mode.
The mode for Omni Port pairs or ranges can be configured using the following
privileged configuration command:
CN 4093(config)# [no] system port <low port>-<high port> type fc
On the CN4093, each Fibre Channel network connected to the switch must be
assigned its own VLAN. For each VLAN used with Fibre Channel, following
properties must be defined:
 VLAN number
Switch role (NPV mode or full fabric mode)

 Port membership
Fibre Channel ports roles (as uplink ports or node connections)

The following commands are used to define a typical VLAN:
 Set or delete a VLAN
CN 4093(config)# [no] vlan <VLAN number>
FCoE networks typically use VLAN 1002. If using a different VLAN for FCoE,
be sure that any connected servers and FCoE bridge will support your selection.
This command initiates VLAN configuration mode. All VLAN‐related Fibre
Channel configuration is performed in this mode.
Enable or disable the VLAN

CN 4093(config-vlan)# [no] shutdown
Exit VLAN configuration mode

CN 4093(config-vlan)# exit
As with typical VLAN configuration, each VLAN used with a Fibre Channel
network must include a description of its port members. VLANs used in Fibre
Channel networks follow typical VLAN configuration rules (see "VLANs" on
page 137), with the following additions:
 An FC port may belong to only one Fibre Channel VLAN.
 Trunking must be enabled for FCoE Ports and these ports must be part of the
Fibre Channel VLAN.
At least one Fibre Channel port must be included in each Fibre Channel VLAN.
