Access Mode

FCoE Mode

Auto-VLAN Mode

© Copyright Lenovo 2015
In access mode, a vPort carries packets with inner tags that belong to one VLAN.
The vPort is associated with the VLAN defined by the command:
CN 4093(config_ufp_vport)# network default-vlan <2-4094>
Note: VLANs 4002-4009 are reserved for outer tagging.
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. 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 is 1024 when switch is configured in standalone mode.
The vPort cannot be configured in Virtual Ethernet Port Aggregator (VEPA) mode.
