While configuring or unconfiguring the FC-Gateway uplink, the uplink interface flaps. As UFD is enabled by default for NPG
(FCGateway Uplink) in SmartFabric mode; UFD brings down the server facing ports which are deployed with same FCoE
VLAN as FCGateway uplink.
Fibrechannel port flaps are observed on the IOM side if the IOM is operationally up and is connected to a storage device
without configuring the FCDirectAttach uplink (vfabric) on this port. These flaps are induced by the storage device, as the
storage device is unable to login to the IOM until the configuration on this port is applied. After the FCDirectAttach uplink
(vfabric) configuration is completed on this port, the flaps stop and the storage device logs in to the IOM switch.
NPIV Proxy Gateway cascading
OS10 supports connecting two switches as NPIV Proxy Gateways (NPIVs) between Converged Network Adapters (CNAs) or
Fibre Channel Host Bus Adapters (FC HBAs) and FCoE Forwarder (FCF) switches.
In the following figure, NPG1 and NPG2 connect to each other which provide FCoE and FC services for CNA1 and FC HBA1, and
the FCF1 switch.
NPG1 switch configuration
1. Enable the NPG feature.
OS10(config)# feature fc npg
2. Configure vFabric.
OS10(config)# vfabric 2
OS10(confvfabric2)# vlan 1000
OS10(confvfabric2)# name fcoe_fabric
OS10(confvfabric2)# fcoe fcmap 0efc02
3. Apply the vFabric configuration on the interface that connects to FC HBA and change the port mode to F_Port.
OS10(config)# interface fibrechannel 1/1/21
OS10(confiffc1/1/21)# vfabric 2
4. Apply the vFabric configuration on the interface that connects to CNA 1.
OS10(config)# interface ethernet 1/1/50
OS10(confifeth1/1/50)# vfabric 2
