UFP Considerations

NE2552E Application Guide for ENOS 8.4
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
 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.
