GS748T Software User Manual IEEE 802.1Q VLANs Packets received by the switch are treated in the following way: • When an untagged packet enters a port, it is automatically tagged with the port’s default VLAN ID tag number. Each port has a default VLAN ID setting that is user-configurable (the default setting is 1). -
Page 63: Port-Based Vlans
GS748T Software User Manual 4. The following situations produce results as described: • If an untagged packet enters Port 1, the switch tags it with a VLAN tag value 10. The packet has access to Port 2 and Port 3. The outgoing packet is stripped of its tag to leaves Port 2 as an untagged packet. -
