Managing VLANs

This chapter describes the VLAN functionality supported by the Cisco 12000/10720 Router Manager application and guides you through the process of creating and configuring VLAN objects. VLANs support logical grouping of network nodes to reduce broadcast traffic and allow more control in implementing security policies.

The main advantages of VLANs are efficient traffic separation and excellent bandwidth utilization. VLANs improve scaling by logically segmenting the physical LAN structure into sub-networks so that the packets are switched between ports within the same VLAN. This proves to be beneficial for security, broadcast containment, and accounting.

The Cisco 12000/10720 Router Manager facilitates the configuration of VLANs and also manages these VLANs that are provisioned from the EMS. Cisco 12000/10720 Router Manager also provides a synchronization facility so that the VLAN information is retrieved from the entire network, when the sync is initiated for the first time.

This chapter provides the following information:

Launching the VLAN Windows

VLAN Synchronization

Deploying VLAN objects

VLAN Configuration

VLAN Performance

Reparenting VLANs and VLAN Sub-Interfaces

Deleting VLAN Objects

Launching the VLAN Windows

Table 13-1displays each object type that can be used to open the Cisco 12000/10720 Router Manager windows that allow you to view performance, configuration, and synchronization of the VLAN objects.

Note Table 13-1lists the menu options for launching the VLAN dialogs from the VLAN view.

These windows have to be launched from the VLAN objects in the VLAN view. For example, the VLAN Performance window can be launched from a Site and Chassis, but cannot be launched from a module or an Interface object.
