CN4093 Application Guide for N/OS 8.3
From within VLAN configuration mode, the following command is used to add or
remove port members:
CN 4093(config-vlan)# interface port <port number, alias or range>
CN 4093(config-if)# switchport trunk allowed vlan [add|remove] <VLAN ID>
For example:
CN 4093(config-vlan)# interface port INTA5,INTB5,INTC5
CN 4093(config-if)# switchport mode trunk
CN 4093(config-if)# switchport trunk allowed vlan 1,1002
CN 4093(config-if)# exit
CN 4093(config)# interface fc EXT11, EXT12
CN 4093(config-if)# switchport trunk allowed vlan 1,1002
CN 4093(config-if)# exit
Notes:
a. When using port aliases to specify a small range of internal ports, the aliases
are converted to regular port numbers before applying the range. For example,
specifying inta5-intc5 (mixing A and C aliases) would result in a broad
range than includes all ports between 5 (INTA5) and 33 (INTC5), and not just
the lesser group of INTA5, INTB5, and INTC5.
b. FC Omni ports should also be members of VLAN 1 (default vlan), whereas
FCoE ports can have any native VLAN. Fibre Channel VLAN must not be
configured as the native vlan of the FCoE ports.
The switch's role in the Fibre Channel network can be defined on a per-VLAN
basis. The administrator can specify one of the following modes:
 NPV mode to uplink one or more nodes to a full fabric switch
 Full fabric mode
The CN4093 supports up to 12 Fibre Channel VLANs at any given time. Only one
mode can be active on any specific VLAN at a given time, and only one VLAN can
operate in full fabric mode.
From within VLAN configuration mode, the following commands are used to
specify the Fibre Channel mode:
To enable or disable NPV mode:

CN 4093(config-vlan)# [no] npv enable
 To enable or disable full fabric mode:
CN 4093(config-vlan)# [no] fcf enable
Note: Trunking must be enabled for FCoE Ports and these ports must be part of the
Fibre Channel VLAN (NPV/FCF).
