Configuring and Managing Ports and VLANs

You cannot remove the default VLAN (VLAN 1). However, you can add and remove
ports. You can also rename the default VLAN, but D-Link recommends against it.

Note.
The display can include DWL-8220AP access ports and wired authentication ports,
because MSS dynamically adds these ports to a VLAN when handling user traffic for the
VLAN.
Managing the Layer 2 Forwarding Database
A DWS-1008 switch uses a Layer 2 forwarding database (FDB) to forward traffic within a
VLAN. The entries in the forwarding database map MAC addresses to the physical or virtual
ports connected to those MAC addresses within a particular VLAN. To forward a packet to
another device in a VLAN, the switch searches the forwarding database for the packet’s
destination MAC address, then forwards the packet out the port associated with the MAC
address.
Types of Forwarding Database Entries
The forwarding database can contain the following types of entries:
• Dynamic - A dynamic entry is a temporary entry that remains in the database only
until the entry is no longer used. By default, a dynamic entry ages out if it remains
unused for 300 seconds (5 minutes). All dynamic entries are removed if the switch
is powered down or rebooted.
• Static - A static entry does not age out, regardless of how often the entry is used.
However, like dynamic entries, static entries are removed if the switch is powered
down or rebooted.
• Permanent - A permanent entry does not age out, regardless of how often the
entry is used. In addition, a permanent entry remains in the forwarding database
even following a reboot or power cycle.
