Vlans In Layer 2 Only Mode - D-Link DES-3326 User Manual

DES-3326 Layer 3 Fast Ethernet Switch User's Guide
A switch that implements layer 3 (or 'subnet') VLANs without
performing any routing function between these VLANs is referred
to as performing 'IP Switching'.
Note: IP switching does not allow packets to cross VLANs
without a network device performing a routing function
between the VLANs (IP subnets).

VLANs in Layer 2 Only Mode

The switch initially configures one VLAN, VID = 1, called the
DEFAULT_VLAN. The factory default setting assigns all ports on
the switch to the DEFAULT_VLAN.
configured, there respective member ports are removed from the
DEFAULT_VLAN.
Packets cannot cross VLANs if the switch is in Layer 2 Only
mode. If a member of one VLAN wants to connect to another
VLAN, the link must be through an external router.
When the switch is in Layer 2 Only mode, 802.1Q VLANs are
supported.
Note: If no VLANs are configured on the switch and the
switch is in Layer 2 Only mode, then all packets will be
forwarded to any destination port. Packets with unknown
source addresses will be flooded to all ports. Broadcast and
multicast packets will also be flooded to all ports.
Note: Each IP interface on the switch corresponds to a
VLAN. The VLAN must be configured before the IP
interface can be setup. The IP interface must have the same
name (and the same VID number)
VLAN.
Note: A VLAN that does not have a corresponding IP
interface defined for it, will function as a Layer 2 Only
VLAN – regardless of the Switch Operation mode.
