UFP Limitations

CN4093 Application Guide for N/OS 8.2
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.
UFP port in FCoE mode cannot operate with FIP auto‐VLAN feature.

 VLANs that have member vPorts configured in trunk‐, access‐, or auto‐modes
cannot have member vPorts configured in tunnel mode or FCoE.
 vPorts on a physical port must be members of separate VLANs.
 VLANs 4002‐4005 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, or auto
modes.
 UFP bandwidth is guaranteed lossless only for unicast traffic.
VMready is supported only on a vPort which is configure in auto‐VLAN mode.

When a vPort is in auto‐VLAN mode, it can support up to 32 VMGroups.
 EVB is supported only on a vPort which is configured in auto‐VLAN mode.
 VMready and EVB cannot be configured on the same physical port.
UFP vPorts support up to 1024 VLANs in trunk and auto‐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.
 When integrating with private VLANs, UFP is not supported in stacking mode.
A maximum of four vPorts can be configured for each physical switch port.

 UFP and vNIC cannot be configured enabled at the same time on a switch.
VMReady Local Group configuration is not supported by UFP.
