UFP Considerations
The following limitations apply when configuring UFP:
 FCoE must be configured only on vPort 2 of the physical NIC for Emulex CNA
and on vPort 1 of the physical NIC for Qlogic CNA. For Qlogic Jawa CNA, FCoE
must be configured on vPort 2.
 VLANs that have member vPorts configured in trunk or access modes cannot
have member vPorts configured in tunnel mode or FCoE.
 vPorts on a physical port must be members of separate VLANs.
 VLANs 4002 ‐ 4009 are reserved for outer tagging.
 A UFP ‐ enabled port with no vPorts configured cannot belong to the same
VLAN as a UFP ‐ enabled port that has vPorts configured in trunk, access modes.
 UFP bandwidth is guaranteed lossless only for unicast traffic.
 UFP vPorts support up to 1024 VLANs in trunk mode on the switch in
standalone mode.
 When CEE is turned on, FCoE vPort must be used for lossless priority traffic. For
loss ‐ tolerant priority traffic, a non ‐ FCoE UFP vPort must be used. The lossless
property of FCoE vPort is not guaranteed, if lossless and loss ‐ tolerant traffic are
combined.
 When the vPort is enabled and the channel link state is up, the system does not
support changing vPort VLAN type from private/non ‐ private to
non ‐ private/private.
 A maximum of eight vPorts can be configured for each physical switch port.
QoS Enhanced Transmission Selection (ETS) mode must be enabled when
configuring more than four vPorts of a physical switch port. For more details
about ETS mode, check page 290 .
 If QoS ETS mode is used, a FCoE vPort must be configured with priority 3.
 UFP vPorts cannot be aggregated to form a LAG/vLAG client.
 An UFP vport cannot be enabled or disabled if a static IGMP entry (group or
multicast router) is configured on it.
