Ports are either physical ports (NICs), or virtualized ports such as interface groups or VLANs. Interface groups treat several physical ports as a single port, while VLANs subdivide a physical port into multiple separate virtual ports.
The underlying physical port or interface group ports for a VLAN port can continue to host LIFs, which transmit and receive untagged traffic.
The port naming convention is e<number>letter:
"e" represents Ethernet.
The numeral 0 indicates that the port is on the node's motherboard.
"a" indicates the first port, "b" indicates the second port, and so on.
For example, "e0b" indicates that an Ethernet port is the second port on the node's motherboard.
VLANs must be named by using the syntax: port_name-vlan-id. "port_name" specifies the physical port or interface group and "vlan-id" specifies the VLAN identification on the network. For example, "e1c-80" is a valid VLAN name.
