• Add – Adds a new VLAN group to the current list. • Remove – Removes a VLAN group from the current list. If any port is assigned to this group as untagged, it will be reassigned to VLAN group 1 as untagged. Adding Static Members to VLANs (VLAN Index) 23 Web – Click VLAN, 802.1Q VLAN, Static List. To create a new VLAN, enter the VLAN ID and VLAN name, mark the Enable checkbox to activate the VLAN, and then click Add. Figure 23-4 VLAN Static List - Creating VLANs CLI – This example creates a new VLAN. Console(config)#vlan database 52-5 Console(config-vlan)#vlan 2 name R&D media ethernet state active 52-6 Console(config-vlan)#end Console#show vlan 52-17 VLAN ID: 1 Type: Static Name: DefaultVlan Status: Active Ports/Port Channels: Eth1/ 1(S) Eth1/ 2(S) Eth1/ 3(S) Eth1/ 4(S) Eth1/ 5(S) Eth1/ 6(S) Eth1/ 7(S) Eth1/ 8(S) Eth1/ 9(S) Eth1/10(S) Eth1/11(S) Eth1/12(S) Eth1/13(S) Eth1/14(S) Eth1/15(S) Eth1/16(S) Eth1/17(S) Eth1/18(S) Eth1/19(S) Eth1/20(S) Eth1/21(S) Eth1/22(S) Eth1/23(S) Eth1/24(S) . . . VLAN ID: 2 Type: Static Name: R&D Status: Active Ports/Port Channels: Console# Adding Static Members to VLANs (VLAN Index) Use the VLAN Static Table to configure port members for the selected VLAN index. Assign ports as tagged if they are connected to 802.1Q VLAN compliant devices, or untagged they are not connected to any VLAN-aware devices. Or configure a port as forbidden to prevent the switch from automatically adding it to a VLAN via the GVRP protocol. Notes: 1. You can also use the VLAN Static Membership by Port page to configure VLAN groups based on the port index (page 23-9). However, note that this configuration page can only add ports to a VLAN as tagged members. 2. VLAN 1 is the default untagged VLAN containing all ports on the switch, and can only be modified by first reassigning the default port VLAN ID as described under “Configuring VLAN Behavior for Interfaces” on page 23-10. 23 VLAN Configuration Command Attributes • VLAN – ID of configured VLAN (1-4093). • Name – Name of the VLAN (1 to 32 characters). • Status – Enables or disables the specified VLAN. -Enable: VLAN is operational. -Disable: VLAN is suspended; i.e., does not pass packets. • Port – Port identifier. • Trunk – Trunk identifier. • Membership Type – Select VLAN membership for each interface by marking the appropriate radio button for a port or trunk: -Tagged: Interface is a member of the VLAN. All packets transmitted by the port will be tagged, that is, carry a tag and therefore carry VLAN or CoS information. -Untagged: Interface is a member of the VLAN. All packets transmitted by the port will be untagged, that is, not carry a tag and therefore not carry VLAN or CoS information. Note that an interface must be assigned to at least one group as an untagged port. - Forbidden: Interface is forbidden from automatically joining the VLAN via GVRP. For more information, see “Automatic VLAN Registration” on page 23-2. -None: Interface is not a member of the VLAN. Packets associated with this VLAN will not be transmitted by the interface. • Trunk Member – Indicates if a port is a member of a trunk. To add a trunk to the selected VLAN, use the last table on the VLAN Static Table page. Web – Click VLAN, 802.1Q VLAN, Static Table. Select a VLAN ID from the scroll-down list. Modify the VLAN name and status if required. Select the membership type by marking the appropriate radio button in the list of ports or trunks. Click Apply. Figure 23-5 VLAN Static Table - Adding Static Members Adding Static Members to VLANs (Port Index) 23 CLI – The following example adds tagged and untagged ports to VLAN 2. Console(config)#interface ethernet 1/1 45-1 Console(config-if)#switchport allowed vlan add 2 tagged 52-11 Console(config-if)#exit Console(config)#interface ethernet 1/2 Console(config-if)#switchport allowed vlan add 2 untagged Console(config-if)#exit Console(config)#interface ethernet 1/13 Console(config-if)#switchport allowed vlan add 2 tagged Console(config-if)# Adding Static Members to VLANs (Port Index) Use the VLAN Static Membership by Port menu to assign VLAN groups to the selected interface as a tagged member. Command Attributes • Interface – Port or trunk identifier. • Member – VLANs for which the selected interface is a tagged member. • Non-Member – VLANs for which the selected interface is not a tagged member. Web – Open VLAN, 802.1Q VLAN, Static Membership by Port. Select an interface from the scroll-down box (Port or Trunk). Click Query to display membership information for the interface. Select a VLAN ID, and then click Add to add the interface as a tagged member, or click Remove to remove the interface. After configuring VLAN membership for each interface, click Apply. Figure 23-6 VLAN Static Membership by Port CLI – This example adds Port 3 to VLAN 1 as a tagged port, and removes Port 3 from VLAN 2. Console(config)#interface ethernet 1/3 45-1 Console(config-if)#switchport allowed vlan add 1 tagged 52-11 Console(config-if)#switchport allowed vlan ...
