FCoE Mode
Auto-VLAN Mode
© Copyright Lenovo 2016
FCoE traffic is carried by a vPort. The server‐side endpoint of this virtual port will
be represented through a FC vHBA. Setting a virtual port in FCoE mode will
enable Priority‐based Flow Control (PFC) on the physical port.
A vPort configured in FCoE mode can only be attached to a Fibre Channel (FC)
VLAN. Only vPort 2 on a physical port can be configured in FCoE mode. A vPort
in FCoE mode operates as a local domain data path type with packets being single
tagged.
When a vPort is configured in auto‐VLAN mode, the vPort participates in VM
discovery using VMready or 802.1Qbg. VLANs are dynamically provisioned based
on VMready discovery or 802.1Qbg VM association.
When a vPort operates in auto‐VLAN mode, it supports 32 VM groups. In the case
of 802.1Qbg, when a vPort operates in auto‐VLAN mode, the maximum number of
VLANs in the inner tag are 1024. The vPort cannot be configured in Virtual
Ethernet Port Aggregator (VEPA) mode.
