| Does batch VLAN deployment automatically filter out devices? |
|
Yes. Some devices will be filtered after you select a group in batch VLAN deployment.

According to the features to be deployed, VLAN Manager can filter devices that do not support the deployed features. |
| Why isn't the interface information of Juniper EX4200 devices displayed in the system VLAN management? |
|
The default VLAN is 0 on Juniper EX4200 devices. All interfaces belong to VLAN 0 by default. However, VLAN 0 is considered an invalid VLAN in the system VLAN management and the system VLAN management filters all interfaces of the Juniper EX4200 devices. To solve this problem, modify the default VLAN into VLAN 1 for Juniper EX4200 devices. |
| Why isn't the VLAN range of Juniper EX4200 devices displayed in the system VLAN management? |
