Configuring VLANs
You can use virtual LANs (VLANs) to divide the network into separate logical areas. VLANs can also
be considered as broadcast domains.
Any switch port can belong to a VLAN, and unicast, broadcast, and multicast packets are forwarded and
flooded only to end stations in that VLAN. Each VLAN is considered a logical network, and packets
destined for stations that do not belong to the VLAN must be forwarded through a router.

Understanding VLANs
VLAN Trunking Protocol (VTP) mode is OFF. VTP BPDUs are dropped on all interfaces of a Cisco
Note
Nexus 5000 Series switch, which partitions VTP domains if other switches have VTP turned on.
A VLAN is a group of end stations in a switched network that is logically segmented by function, project
team, or application, without regard to the physical locations of the users. VLANs have the same
attributes as physical LANs, but you can group end stations even if they are not physically located on
the same LAN segment.
Any port can belong to a VLAN, and unicast, broadcast, and multicast packets are forwarded and flooded
only to end stations in that VLAN. Each VLAN is considered a logical network. Packets destined for
stations that do not belong to the VLAN must be forwarded through a router.
