How to Conﬁgure VLANs on the Switch

	How to Conﬁgure VLANs on the Switch
	IEEE 802.1Q compliant devices and legacy/untagged VLANs can coexist
	on the same networks, but legacy/untagged VLANS require a separate
	link, whereas the 802.1Q tagged VLANs can combine several VLANs
	into one link. On 802.1Q-compliant devices, separate ports (conﬁgured as
	untagged) must be used to connect separate VLANs to non-802.1Q
	devices.

VLAN 4 tagged VLAN

When you assign a switch port to a given VLAN, you must implement the VLAN tag if the switch port will carry trafﬁc for more than one VLAN. Otherwise, the port VLAN assignment can remain untagged because the tag is not needed. On a given switch, use the untagged designation for a port VLAN assignment where the port is connected to a non-802.1Q-compliant device or is assigned to only one VLAN as in VLAN 1 in Figure 2-2. Use the tagged designation when more than one VLAN is assigned to the port, or the port is connected to a device that does comply with the 802.1Q standard as in VLANs 2 through 4 in Figure 2-2. These simple rules are summarized in Table 2-1.
