# Multiple VLAN

### 1. Summary

You can divide the ports of a single switch into multiple groups, and block communication between groups. In addition to grouping ports intomultiple groups, a single port can also be joined to multiple groups.For example, a port that is connected to a terminal that mustcommunicate with all groups, such as a server or router, would be joined to each and every group.

For multiple VLANs, the same IP address is assigned even if the group is different.

The agentes for which a multiple VLAN can be set, as well as themaximum number of groups that can be set for each agent on this page are shown below.

### 2. Multiple VLAN page structure

The multiple VLAN page consists of three views: tree view, multiple VLAN settings view, and connected devices view.

#### 2.1. Tree view

These are the same as shown in the map.

The agent topology starting at the manager is shown in the lower left of the screen. Network devices of other manufacturers are not shown. In the "Tree view," press the "Devices" icon to see deviceinformation in the "Connected devices view". If a agent that supportsmultiple VLANs is selected, settings are shown in "Multiple VLANsettings view".

#### 2.2. Multiple VLAN settings view

The multiple VLAN settings of the agent selected in "Tree view" areshown. This is not shown if a manager or agent that does not supportmultiple VLANs is selected in "Tree view".

- List of multiple VLAN group settings

  The status of the joined ports for each group of the multipleVLAN are shown in the form of a table. The horizontal direction of thetable shows the ports, and the vertical direction shows the groups.

  In the table, you can press the Port icon to change the port join status of the corresponding group. A Port icon that is in the joined state will change to the color that corresponds to the group (example: ). If you once again press a port icon that is in the joined state, it returns to the non-joined state.

  Pressing the "Port number" button in the upper edge of the table will select the ports of all groups in the Port column, and pressing the "Group number" button in the left edge of the table will select all ports in the Group line. By pressing the "↘" button in the upper left of the table, you can select diagonally staggered ports from the upper left.

  Ports that are not disabled will not be changed status by any specify method.

  All ports that belong to the logical interface will be showntogether, as displayed on the right side of the table.The logicalinterface type and number will be shown as a two-row label above theport numbers.

  The logical interface type (sa or po) is shown on the upper row, and the interface number is shown on the bottom row.

  Static link aggregation is shown for "sa", and LACP link aggregation is shown for "po".

  When operating the group join status of the ports that belong tothe logical interface, the same settings will be applied to all portsbelonging to the same logical interface.

  - Ports/groups to display

    Move the slider on the bar to change the ports and groups shown on the screen.

    The upper bar is for ports, and the lower bar is for groups.

    The left-hand slider changes the minimum value, and the right-hand slider changes the maximum value.

  - Minimized view

    Select the check box to display a minimized view of the port and group icons.

    When using the minimized view, the arrows for port uplinks and downlinks will not be displayed.

  - "Return all groups to the state prior to the change" button

    Return the ports joined to the multiple VLAN to the state prior to the change.

  - "OK" button

    Apply the settings of the ports joined to the multiple VLAN.

    These settings will also apply to ports that are hidden.

    The "Multiple VLAN group setting list" can be switched between displayed and hidden by pressing the button in the upper left.

#### 2.3. The contents of the settings for a previously-specified multiple VLAN group are shown by the switch graphic in the lower part of "MultipleVLAN settings view".

- Group select pulldown menu

  Select the multiple VLAN group that is shown by the switch image at the right side.

- Switch image

  Ports that are joined to the group currently selected in the group select pulldown menu are shown.

#### 2.4. Connected devices view

These are the same as shown in the map.

Devices that are connected to the manager or agent selected in the"Tree view" are shown in the lower right of the screen. If "Devicemanagement" is not enabled in "LAN map settings," terminal information(e.g., PC or mobile devices) is not shown.

If a switch is selected as a agent, you can check the type of devicethat is connected to each port of the switch, and use this as areference when making multiple VLAN group settings.

- Acquisition date

  This is the time at which information was last obtained forequipment that is connected to the manager or agent selected in the"Tree view". This is not shown if "Device management" is not enabled in"LAN map settings".

- Select page

  Page numbers are shown for the list of currently-displayed terminals. Press or or enter a numeric value to move between pages.

- Acquire button

  This obtains information for terminals that are connected to themanager or agent selected in the "Tree view". This is not shown if"Device management" is not enabled in "LAN map settings".

- List

  Information is listed for equipment that is connected to themanager or agent selected in the "Tree view". You can press each item’s Sort switch to sort the list. The initial screen is sorted in order of port.

  The VLAN ID item shows (A) for an access VLAN or (T) for a trunk VLAN.

  If the port is being used as a port for a private VLAN, the VLAN ID is not shown, and (P) is shown.

  If the port is being used as a port for a voice VLAN, the VLAN ID is not shown, and (V) is shown.

### 3. Making settings for multiple VLAN groups

To make multiple VLAN group settings, first select the switch thatyou want to set from the "Tree view". When you make a selection, the"Multiple VLAN group settings list" appears in the "Multiple VLANsettings view".

When the "Multiple VLAN group settings list" appears, select theports that you want to join to each group by pressing the corresponding Port icon. When making settings, refer to the following tips.

When you finish selecting the ports to join, press the "OK" button to apply the settings to the switch and complete the settings.

Tips when selecting multiple VLAN settings

- You want to select ports efficiently

  By using the "Port number" button in conjunction with the "↘" button you can select ports efficiently.
  You can use the "Port number" button to allow a specificport to communicate with all other ports. For example, the uplink portnormally needs to be able to communicate with all other ports, so it isjoined to all groups; by pressing the "Port number" button in the column of the uplink port, you can avoid the trouble of selecting them individually.
  Use the "↘" button when you want to join each port to adifferent group. For example, if you want to block all communicationbetween each downlink port, and allow communication only with the uplink port, press the "Port number" button and "↘" button inthe uplink port column; each group is joined to the uplink port and toone downlink port, allowing you to easily obtain the desired settings.Such settings are often used for a network in an Internet-equippedapartment building.

- When you want to restrict the ports and groups to configure

  Adjust the bars for the "Ports/groups to display" to show only the ports and groups that you need.

- You want to re-do the settings

  By pressing the "Return all groups to the state prior to change" button you can return the joined port selection state to the state prior to change.

### 4. Showing settings for multiple VLAN groups

Multiple VLAN groups that have already been specified are indicatedby the switch graphic that is shown at the bottom of the "Multiple VLANsettings view". From the pulldown at the left, select the group that you want to check; the ports that are joined to that group change to thecolor corresponding to the group.

The contents of the settings shown here are the settings that have been actually applied to the switch by pressing the "OK" button. The content that is currently being edited in the "Multiple VLAN group settings list" is not reflected in the display.
