Virtual fabric

Virtual fabrics (vfabric) divide a physical fabric into logical fabrics. Manage each vfabric independently. The fabric ID identifies each vfabric. You can configure only one vfabric in F_Port mode and multiple vfabrics in NPG mode. F_Port and NPG modes are mutually exclusive.

If you have already configured a vfabric in F_Port mode, while configuring vfabrics in NPG mode, disable F_Port mode. When you disable F_Port mode, the existing vfabric is removed and you must configure new vfabrics in NPG mode. If you are moving from NPG mode to F_Port mode, disable NPG mode and create the new vfabric in F_Port mode.

Zoning allows you to increase network security by partitioning the devices connected to the vfabric into subsets. Partitioning restricts unnecessary interactions between the members of vfabric. For more information, see Fibre Channel zoning.

After configuring a vfabric ID, you can create a name, associate a VLAN to carry traffic to the vfabric, configure FCoE parameters, configure the default zone, and activate the zoneset.

NOTE: Do not associate a VLAN that is already in use as a vfabric VLAN.

To configure a vfabric in F_Port mode:

  1. Configure a vfabric using the vfabric fabric-ID command in CONFIGURATION mode. The switch enters vfabric CONFIGURATION mode
  2. Associate a VLAN ID to the vfabric with the vlan vlan-ID command.
  3. Add an FC map with the fcoe fcmap fc-map command.
  4. Activate a zoneset using the zoneset activate zoneset-name command.
  5. Allow access to all logged-in members in the absence of an active zoneset configuration using the zone default-zone permit command. The logged-in members are the FC nodes that are successfully logged into the FC fabric, identified by the vfabric.
  6. (Optional) Add a name to the vfabric using the name vfabric-name command.
  7. Apply the vfabric to FC interfaces using the vfabric fabric-ID command in FC INTERFACE mode.
Example configuration of vfabric in F_Port mode
OS10(config)# vfabric 100
OS10(conf-vfabric-100)# name 100
OS10(conf-vfabric-100)# vlan 1023
OS10(conf-vfabric-100)# fcoe fcmap 0xEFC64
OS10(conf-vfabric-100)# zoneset activate set

To configure a vfabric in NPG mode:

  1. Configure a vfabric using the vfabric fabric-ID command in CONFIGURATION mode. The switch enters vfabric CONFIGURATION mode.
  2. Associate a VLAN ID to the vfabric with the vlan vlan-ID command.
  3. Add FCoE parameters with the fcoe {fcmap fc-map | fcf-priority fcf-priority-value | fka-adv-period adv-period | vlan-priority vlan-priority-value | keep-alive} command.
  4. (Optional) Add a name to the vfabric using the name vfabric-name command.
  5. Apply the vfabric to interfaces using the vfabric fabric-ID command in INTERFACE mode.
Configure vfabric in NPG mode
OS10(config)# vfabric 10
