12 VLAN management
With IMC, you have a convenient facility for managing VLANs globally or on a per device basis. With
IMC Global VLAN option, you can simplify the process of creating standardized VLANs across devices
in the infrastructure. Using the Global VLAN option, you can create VLANs and select from the list of all
managed devices, which devices to add the VLAN to or remove the VLAN from.
With IMC Batch Deploy option, you can create and configure VLANs on one or more devices, including
configuring access, trunk, or hybrid ports.
For individual device VLAN management, you can select the device they want to configure VLANs for.
From the VLAN configuration page, you can configure a VLAN for the selected device as well as
configure virtual interfaces, access ports, trunk ports, or hybrid ports for each VLAN.
In addition, you can view histories of VLAN management operations using IMC VLAN Deployment Task
option.
Finally, with IMC VLAN Topo option, you can launch a network topology view that highlights devices for
the selected VLAN and grays out devices that are not part of the VLAN. You can actively monitor and
manage devices in the selected VLAN from the topology map.
Global VLAN management
IMC Global VLAN management feature makes it simple and easy to create standardized VLANs for one,
some, or all devices in the network infrastructure. With the Global VLAN option, you can add a VLAN to
all switches in the network simply by defining the VLAN ID, the VLAN name and by selecting the devices
to add the VLAN to. In addition, you can easily add, modify or delete VLANs on selected devices.
Viewing the global VLAN list
The Global VLAN List provides you with a list of all VLANs configured on devices managed by IMC that
IMC is aware of.
To view the VLANs in the network infrastructure:
1. Navigate to VLAN Management > Global VLAN:
a. Click the Service tab from the tabular navigation system on the top.
b. Click the VLAN Management on the navigation tree on the left.
c. Click Global VLAN link located under VLAN Management on the navigation tree on the left.
The global VLAN list appears.
2. Do one of the following:
{
When the VLAN ID and VLAN Name Identification Mode box is not selected, a VLAN ID
uniquely identifies a global VLAN, so the global VLAN list for a VLAN ID displays only one
VLAN. This mode is recommended for Layer 2 network management.
{
When the VLAN ID and VLAN Name Identification Mode is selected, the global VLAN list
displays multiple VLANs with the same VLAN ID but different VLAN names. This mode is
recommended for Layer 3 network management.
