This section includes the following topics:
• "Changing VLAN port membership" (page 68) • "Configuring advanced VLAN features" (page 69)
• "Configuring a VLAN to accept tagged or untagged frames" (page 71) • "Configuring a MAC address for auto-learning on a VLAN" (page 73) • "Modifying auto-learned MAC addresses" (page 75)
After a VLAN is created, you cannot change its type. You must first delete the VLAN, and then create a new VLAN of a different type.
Changing VLAN port membership
To change the port membership of a VLAN:
Step Action
1 Select VLAN > VLANs on the Device Manager menu bar. The VLAN dialog box appears, with the Basic tab selected. See Figure 20 "VLAN dialog box - Basic tab" (page 58).
2 Double-click the PortMembers field for the VLAN whose ports you want to change.
The PortMembers, VLAN dialog box for the VLAN appears. See "PortMembers, VLAN dialog box" (page 68).
PortMembers, VLAN dialog box
3 Click the port members to add or remove. Ports that display in gray cannot be added to the VLAN. (For example, you cannot select ports that are not in the same STG.)
4 Click Ok.
The PortMembers dialog box closes and the changes appear in the Basic tab.
Managing a VLAN 69
5 Click Apply.
6 Click Close.
The port membership for the VLAN is changed and the VLAN dialog box closes.

Configuring advanced VLAN features
The Advanced tab contains advanced fields, including the Vlan Operation
Action field, which is useful when troubleshooting.
Step Action
1 Select VLAN > VLANs from the Device Manager menu bar. The VLAN dialog box appears, with the Basic tab selected. See Figure 20 "VLAN dialog box - Basic tab" (page 58).
2 Click the Advanced tab.
The Advanced tab appears. See"VLAN dialog box - Advanced tab" (page 69).

Table 9
VLAN - Advanced tab fields
Field Description
Id The VLAN ID.
Name The name of the VLAN.
IfIndex The logical interface index assigned to the VLAN.
Type Type of VLAN:
• byPort
• byIpSubnet
• byProtocolId
MacAddress The MAC address assigned to the virtual router interface for this VLAN. This field applies only when the VLAN is configured for routing. This MAC address is used as the Source MAC in routed frames and ARP replies.
Vlan Operation Action One of the following VLAN-related actions:
• none — None of the following updates are made.
• flushMacFdb — flush MAC forwarding table for VLAN
• flushArp — flush ARP table for VLAN
• flushIp — flush IP route table for VLAN. When this command is executed, a RIP request is immediately sent out to solicit the updated RIP routes.
• all — flush all tables for VLAN. When this command is executed, a RIP request is immediately sent out to solicit the updated RIP routes.
• flushSnoopMem — flush IGMP Snoop Members
• flushSnoopMRtr — flush snoop multicast router
Result Result code for action.
UserDefinedPidList User-defined protocol ID list if the user selected and defined a protocol type.
Encap This encapsulation is for user-defined protocol-based VLANs. The default value is null.
Managing a VLAN 71
Field Description
UpdateDynamicMacQosLevel This field is used to indicate whether to update the QoS level for dynamically learned MAC addresses associated with a subnet-based or protocol-based VLAN. If it is set to ENABLE, the QoS level for all dynamically learned MAC addresses is changed when changing the VLAN QoS level. If set to DISABLE, when a MAC address is learned, the QoS level is not updated when the VLAN QoS level changes.
QosLevel Indicate the quality of service level of the destination Mac Address of incoming frames on this VLAN.
• level0 (lowest priority)
• level1 (default) • level2 • level3 • level4 • level5 • level6
• level7 (highest priority)
Configuring a VLAN to accept tagged or untagged frames
To configure a VLAN to accept tagged or untagged frames from a port:
Step Action
1 Select the port in the Device Manager main window. The port is highlighted.
2 Select Edit > Port from the Device Manager menu bar.
The Port dialog box appears with the Interface tab selected. See "Port dialog box - Interface tab" (page 72).
Port dialog box - Interface tab
3 Click the VLAN tab.
The VLAN tab appears. See"Port dialog box - VLAN tab" (page 72).

4 To configure tagging on the port, select the PerformTagging check box. This setting is applied to all VLANs associated with the port.
Managing a VLAN 73
• If the check box is selected, tagging is enabled. All frames sent from this port are tagged. You can either discard the tagged frames (go to Step 5), send untagged frames to the default VLAN (go to Step 6), or forward them to a VLAN (go to Step 7).
• If the check box is cleared, tagging is disabled. The port does not send tagged frames. The switch removes the tag before sending the frame out the port. You can either discard the untagged frames (go to Step 5), send untagged frames to the default VLAN (go to Step 6), or forward them to a VLAN (go to Step 7).
When you enable tagging on an untagged port, the previous configuration of VLANs and STGs for the port is lost. In addition, the port resets and runs Spanning Tree Protocol, thus breaking connectivity while the protocol goes through the normal blocking and learning states before the forwarding state.
5 To discard untagged frames on a port with tagging enabled, select the DiscardUntaggedFrames check box.
6 To designate a default VLAN to associate with untagged frames, select the UntagPortDefaultVlan check box.
7 To designate a default VLAN to associate with discarded frames, enter a VLAN ID in the DefaultVlanId field (or use the default VLAN 1).
8 Click Apply.
9 Click Close.
Tagging is configured for the port.

Configuring a MAC address for auto-learning on a VLAN
You can manually configure a MAC address for auto-learning on a VLAN port.
To manually configure a MAC address on a VLAN port:
VlanMacLearning dialog box - Manual Edit tab
2 Click Insert.
The VlanMacLearning, Insert Manual Edit dialog box appears. See "VlanMacLearning, Insert Manual Edit dialog box" (page 74).
VlanMacLearning, Insert Manual Edit dialog box
3 Enter the source MAC address in the Address field.
4 Click the ellipsis (...) in the Ports field.
The BridgeManualEditPorts dialog box appears, showing the available ports. See"BridgeManualEditPorts dialog box" (page 74).

5 Click the port numbers of the ports you want to perform VLAN MAC learning.
6 Click Ok.
The BridgeManualEditPorts dialog box closes and the port numbers are added to the Insert Manual Edit dialog box.
7 Click Insert.
The Insert Manual Edit dialog box closes and the MAC address and ports are added to the Manual Edit tab of the VlanMacLearning dialog box.
8 Click Apply.
9 Click Close.
