VLAN Tab (Device)
The Device view of the VLAN tab enables you to do any or all of the following:
- compare (verify) model VLAN definitions with VLAN settings on devices
- update model VLAN definitions with VLAN settings from devices
- write (enforce) model VLAN definitions to devices
To access the Device view of the VLAN tab, select the device(s) or group(s) of interest in the left panel. Then select the VLAN tab in the right panel and confirm that the Device radio button is selected. The Device view of this tab consists of an upper panel and a lower panel. Use the panel control buttons 
to control the display of the two panels.
For more information, see How to Work with VLAN Models.
Click the areas in the window for more information.
Upper Panel
The table in the upper panel provides VLAN information about the device(s) selected in the left panel. You can compare the current VLAN settings on the selected device(s) with the VLAN definitions in the selected VLAN model by clicking Start Verify (Retrieve) 
. Devices on which differences are detected are marked in the table by a red not-equals sign 
.
- VLAN Model
- Select the VLAN model whose VLAN definitions you want to display in the left table of the lower panel.
Device VLANs Table
This table provides VLAN information for the device(s) selected in the left panel. A red not-equals sign 
indicates that there are differences between the VLAN definitions in the model and the VLAN settings on the device(s).
| NOTE: | When you create multiple VLAN models, consult the Max VLANs Supported and Max VLAN ID values in this table, and create your VLANs based on the limitations of the device you are configuring. This will help you to avoid enforcing problems arising from conflicts between the maximums in a template and the maximums supported on a device.

Lower Panel
The left table in this panel shows the VLAN definitions in the VLAN model selected at the top, and the right table shows the VLAN settings on the device selected in the upper table. You can update the VLAN model with selected device settings, if desired.
Note: Egress Lists on the device are not checked to see if the VLAN will be egressing any ports.
VLAN Definitions for Model
This table displays the VLANs defined for the VLAN model selected at the top of the tab.
- VLAN ID
- VLAN ID) Unique numerical identifier of the VLAN.
- Write to Device(s)
- Indicates whether or not the VLAN will be written to the device(s) when you enforce, or compared to the actual VLANs on the device(s) when you verify (Yes or No).
- Dynamic Egress
- Indicates whether or not dynamic egress is enabled for the VLAN (Yes or No).
- IGMP Status
- Indicates whether IGMP (Internet Group Management Protocol) is a factor in this VLAN's definition, and if so, if it is to be enabled or disabled:
- N/A - IGMP is not a part of the VLAN's definition.
- Enable - IGMP is a part of the VLAN's definition, and is enabled.
- Disable - IGMP is a part of the VLAN's definition, but is currently disabled.
- IGMP Version
- For VLANs using IGMP, the version of IGMP that will be utilized on ports associated with the VLAN (Version 1,Version 2).
- Switch Query IP
- The address of the IGMP Querier on the IP subnet to which this interface is attached.
- Query Interval
- Interval (in seconds) between general IGMP queries sent by the device. Larger values cause queries to be sent less often. This value must be greater than the Query Response interval. Valid values: 1 through 300. For more information, see IGMP.
- Query Response
- Maximum amount of time allowed for responses to general IGMP queries. Larger values result in less bursty traffic. This value must be less than the Query Interval. Valid values: 1 through 300. For more information, see IGMP.
- Interface Robustness

VLAN Element Editor Button
- Opens the VLAN Element Editor window where you can modify existing VLAN models or create new ones.
-
Enforce Button - Writes the VLAN selected in the VLAN Definitions for Model table to the device(s). The VLAN's Write VLAN to Devices property must be set in order for its definitions to be enforced. To avoid unpredictable results, allow the enforce to complete before selecting another tab or device.
NOTE: On the X-Pedition router, enforcing will not overwrite the "System Static" VLAN (SYS_L3_Interface Name). However, you can update a VLAN model definition with the System Static VLAN definition from the router.
-
Start/Stop Verify (Retrieve) Button - Compares the selected model's VLAN definitions with the VLAN settings on the selected device(s), and displays the discrepancies in the upper table. Only those VLANs whose Write VLAN to Devices property is set are verified. When you initiate the verification process, this button changes to Stop, and you can stop the verification at any time. If there are no VLAN models against which to compare the device VLAN settings, this button is grayed out. If a difference is detected, a red not-equals sign is displayed in front of the appropriate line in the table.
-
Update (Merge) Button
- Updates the selected VLAN definition in the VLAN Definitions for Model table with the device VLAN settings selected in the right table. To avoid unpredictable results, allow the merge to complete before selecting another tab or device.
CAUTION: This operation cannot be undone.
| NOTE: | Certain devices that allow the creation of VLANs without VLAN names may create VLANs with blank names in the model. You can rename these if you like, or leave them blank. Either way, these VLANs and their properties (modified or not) will be saved when you click Save.
