Configure multiswitch fabric (E Port)

This section describes the procedure to configure multiswitch fabric (E Port).

Configuration notes

  • When two different fabrics join and when both fabrics have the same domain ID configured, the reconfigure fabric (RCF) operation occurs as the domain ID overlaps.
  • The RCF operation results in traffic disruptions and after the RCF operation, each switch in the fabric gets a unique domain ID from the principal switch.
  • During the merge of conflicting domain IDs, the switch may perform an additional RCF to stabilize when the switch name server entries exceed 700.
  • It is recommended to not merge fabrics with conflicting preferred domain IDs.
  • During a switch reboot, with conflicting preferred domain IDs, the switches first assign itself a configured domain ID.
  • When the E Port links of the switch comes up, the RCF operation occurs again as the domain ID overlaps.

The following example shows a simple multiswitch setup that includes switch-1 and switch-2 with default configurations:

To enable the multiswitch mode, you must first disable the current mode. Configure switch-1 and switch-2 to configure the multiswitch fabric.

Configure multiswitch fabric

Switch-1 configuration

  1. Enable the multiswitch feature globally. 
    OS10(config)# feature fc multi-switch
  2. Create a vFabric VLAN. 
    OS10(config)# interface vlan 1001
  3. Create vFabric. 
    OS10(config)# vfabric 1
OS10(conf-vfabric-1)#
    NOTE: The recommended configuration is to configure the same VLAN and fcmap values on all the switches. vFabric ID is of local significance, and hence the vFabric can have different values on different switches.
  4. Create a port group. 
    OS10(config)# port-group 1/1/1
OS10(conf-pg-1/1/1)# no mode
OS10(conf-pg-1/1/1)# mode FC 8g-4x
  5. Configure FC interface. 
    OS10(config)# interface fibrechannel 1/1/1
OS10(conf-if-fc1/1/1)# no shutdown
OS10(conf-if-fc1/1/1)# vfabric 1
OS10(conf-if-fc1/1/1)# exit
OS10(config)# interface fibrechannel 1/1/2
OS10(conf-if-fc1/1/2)# no shutdown
OS10(conf-if-fc1/1/2)# vfabric 1
  6. Configure the FC switch port mode. 
    OS10(conf-if-fc1/1/2)# fc port-mode E
  7. Add VLAN 1001 and fcmap to switch-1 to activate vFabric. 
    OS10(config)# vfabric 1
OS10(conf-vfabric-1)# vlan 1001
OS10(conf-vfabric-1)# fcoe fcmap 0xefc00
OS10(conf-vfabric-1)# exit
  8. Create zones. 
    OS10(config)# fc zone zoneA
OS10(config-fc-zone-zoneA)# member wwn 20:01:f4:e9:d4:f9:fc:44
OS10(config-fc-zone-zoneA)# member wwn 20:02:00:11:0d:a5:56:01
  9. Create and activate a zone set. 
    OS10(config)# fc zoneset zoneset1
OS10(conf-fc-zoneset-zoneset1)# member zoneA
OS10(config)# vfabric 1
OS10(conf-vfabric-1)# zoneset activate zoneset1
  10. You can deactivate vFabric by removing either the VLAN or fcmap configuration. 
    OS10(conf-vfabric-1)# no vlan 100
Warning: All traffic on this fabric will be lost. Continue? [yes/no]:yes

Switch-2 configuration

  1. Enable the multiswitch feature globally. 
    OS10(config)# feature fc multi-switch
  2. Create a vFabric VLAN. 
    OS10(config)# interface vlan 1001
  3. Create a vFabric. 
    OS10(config)# vfabric 1
OS10(conf-vfabric-1)#
  4. Create a port group. 
    OS10(config)# port-group 1/1/1
OS10(conf-pg-1/1/1)# no mode
OS10(conf-pg-1/1/1)# mode FC 8g-4x
  5. Configure FC interface. 
    OS10(config)# interface fibrechannel 1/1/1
OS10(conf-if-fc1/1/1)# no shutdown
OS10(conf-if-fc1/1/1)# vfabric 1
OS10(conf-if-fc1/1/1)# exit
OS10(config)# interface fibrechannel 1/1/2
OS10(conf-if-fc1/1/2)# no shutdown
OS10(conf-if-fc1/1/2)# vfabric 1
  6. Configure the FC switch port mode. 
    OS10(conf-if-fc1/1/2)# fc port-mode E
  7. Add VLAN 1001 and fcmap to switch-2 to activate vFabric. 
    OS10(config)# vfabric 1
OS10(conf-vfabric-1)# vlan 1001
OS10(conf-vfabric-1)# fcoe fcmap 0xefc00
OS10(conf-vfabric-1)# exit
  8. Create zones. 
    OS10(config)# fc zone zoneA
OS10(config-fc-zone-zoneA)# member wwn 20:01:f4:e9:d4:f9:fc:44
OS10(config-fc-zone-zoneA)# member wwn 20:02:00:11:0d:a5:56:01
  9. Create and activate a zone set. 
    OS10(config)# fc zoneset zoneset1
OS10(conf-fc-zoneset-zoneset1)# member zoneA
OS10(config)# vfabric 1
OS10(conf-vfabric-1)# zoneset activate zoneset1
  10. You can deactivate the vFabric by removing either the VLAN or fcmap configuration. 
    OS10(conf-vfabric-1)# no vlan 100
Warning: All traffic on this fabric will be lost. Continue? [yes/no]:yes
