Configuring a Port in General Mode Beginning in Privileged EXEC mode, use the following commands to configure an interface with full 802.1q support and configure the VLAN membership information for the interface. Except when noted as required (for example, when configuring MAB, Voice VLAN, or 802.1x), it is recommended that operators use either trunk or access mode. Command Purpose configure Enter global configuration mode. interface interface Enter interface configuration mode for the specified interface. The interface variable includes the interface type and number, for example gigabitethernet 1/0/3. You can also specify a range of interfaces with the interface range command, for example, interface range gigabitethernet 1/0/8-12 configures interfaces 8, 9, 10, 11, and 12. switchport mode general Configure the interface as a tagged and an untagged layer 2 VLAN interface. switchport general allowed vlan [add|remove] vlan-list {tagged|untagged} Configure the VLAN membership for the port. You can also use this command to change the egress tagging for packets without changing the VLAN assignment. • add vlan-list - List of VLAN IDs to add. Separate nonconsecutive VLAN IDs with a comma and no spaces. Use a hyphen to designate a range of IDs. (Range: 1-4093) • remove vlan-list - List of VLAN IDs to remove. Separate nonconsecutive VLAN IDs with a comma and no spaces. Use a hyphen to designate a range of IDs. • tagged - Sets the port to transmit tagged packets for the VLANs. If the port is added to a VLAN without specifying tagged or untagged, the default is untagged. • untagged - Sets the port to transmit untagged packets for the VLANs. Configuring VLANs 603
