Managing VLANs
This chapter describes the VLAN functionality supported by the Cisco 12000 Manager (C12kM) 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 C12kM facilitates the configuration of VLANs and also manages these VLANs that are provisioned from the EMS. C12kM also provides a synchronization facility so as to retrieve the VLAN information from the entire network.
This chapter provides the following information:
•

Launching the VLAN windows
Table 13-1 displays each object type that can be used to open the C12kM windows that allow you to view performance, configuration, and synchronization of the VLAN objects. These windows have to be launched from the VLAN objects. For example, the VLAN Performance window can be launched from a Site, Shelf and Chassis, but cannot be launched from a module or an Interface object.

VLAN Synchronization
VLAN synchronization is provided to synchronize the EM with the VLAN information present in the network. The synchronization process gets the VLAN information from the devices in the network and all the previous VLAN information is lost. Once the VLAN synchronization is completed, all the VLAN objects and the sub-interfaces are deployed under a DefaultDomain. Refer "VLAN View" section for more details on domains.
Note It is recommended that synchronization should not to be performed at a time when there is heavy load on the system i.e., when all the chassis are in the performance logging state.
Note VLAN synchronization happens only on the chassis which are in a managed state i.e., normal or performance logging state.
To synchronize the VLAN objects, proceed as follows:
Step 1 Right click (on a relevant object icon in the Map Viewer window or from an object pick list) and select the VLAN Management>VLAN Synchronize option. The VLAN synchronization dialog can be launched from the VLAN view or refer to Table 13-1 for information on which objects allow you to launch the VLAN Synchronize window.
Figure 13-1 VLAN Synchronize Window
Step 2 Choose Synchronize to initiate the synchronization process. An Information window appears seeking confirmation whether to proceed with the synchronization or not
Figure 13-2 VLAN Synchronize -
Step 3 Click Yes to continue with synchronization.
Caution Choosing
Yes, initiates the VLAN synchronization process and all the previous performance data and the information related to the VLAN objects is lost.
Step 4 The status of the synchronization process is displayed in the Synchronization Status frame in the VLAN Synchronization window.
Note All the sub-interface objects are created under the VLAN objects which in turn are created under the DefaultDomain in the VLAN view.
Figure 13-3 VLAN Synchronize - Status Window
Deploying VLAN objects
C12kM provides deployment wizard dialogs to deploy a Domain, VLAN and a VLAN sub-interface. All the VLAN related objects are displayed in the VLAN view. Refer "VLAN View" section for more details on VLAN view. A domain is deployed independent of any object. Deploying a VLAN object, typically involves the following steps:
•Deploying a Domain
•Deploying a VLAN and a sub-interface object
Deploying a Domain
To deploy a domain, proceed as follows:
Step 1 Place the cursor over a relevant object to determine the objects you can deploy in the VLAN view.
Step 2 Click and hold down the right mouse button.
Step 3 Select the Deployment>Deploy VLAN Related Objects option.

VLAN Configuration Window—Detailed Description
The VLAN Configuration window displays a single Configuration tab.
Configuration Tab
The Configuration tab (see Figure 13-18) displays two frames: Status and Performance Logging.
Status
The Status frame contains two action buttons:
Commission—Commissions the selected VLAN.
Decommission—Decommissions the selected VLAN.
Performance Logging
The Performance Logging frame contains two action buttons:
Start—Starts the performance polling for the selected VLAN.
Stop—Stops the performance polling for the selected VLAN.
VLAN Performance
The VLAN Performance window displays the current performance information for all the VLANs on a selected chassis. Performance polling is not done on a VLAN object, instead, when a VLAN object is moved to the performance polling state, all the child sub-interfaces are also moved into the performance polling state.
The VLAN Performance section provides the following information:
•Viewing the VLAN Performance Window
•VLAN Performance Window—Detailed Description.
Viewing the VLAN Performance Window
The VLAN performance data is available on a per chassis basis and the performance data is received directly from the device. The VLAN performance window displays the statistics for all the VLANs configured on a selected chassis.
To view the VLAN Performance window, proceed as follows:
Step 1 Right click (on a relevant object icon in the Map Viewer window or from an object pick list) and select the VLAN Management>VLAN Performance option. Refer to Table 13-1 for information on which objects allow you to launch the VLAN Performance window. The VLAN Performance window appears, with the VLAN Performance tab displayed:
Figure 13-23 VLAN Performance Window
Step 2 Choose a Chassis from the list box displayed at the left of the window. The performance information for the selected chassis is displayed.
VLAN Performance Window—Detailed Description.
The VLAN Performance window (see Figure 13-23) displays a single VLAN Performance tab. The VLAN Performance tab has a single tabular frame with the following fields:
VLAN Id—Identifier for the VLAN object.
Packets transmitted—The number of packets transmitted by this VLAN.
Packets Received—The number of packets received by this VLAN.
Reparenting VLANs and VLAN sub-interfaces
After the VLAN synchronization process is completed, all the VLAN objects and their corresponding sub-interface objects are placed under a single domain called the DefaultDomain. Reparenting allows you to relocate a VLAN object under a domain or a sub-interface object under a VLAN as per the requirements.
Reparenting is basically used to relocate the VLAN and sub-interface objects under different domains after synchronization.
Note To reparent a sub-interface object under a VLAN, it is mandatory that the object id of the parent VLAN object should be identical. The VLAN object must be placed under a different domain.
For example: Say, you have deployed two domains, D1 and D2. D1 has a VLAN object V1 with sub-interface E1 placed under it and D2 has a VLAN object V2. It will not be possible to place E1 from domain D1 under V2 in domain D2 as the VLAN ids of the VLAN objects are different. But, if a VLAN object is deployed in D2 having id as V1, it would be possible for you to place sub-interface object E1 under V1 in domainD2.
To reparent a VLAN object, proceed as follows:
Step 1 Right click (on a relevant object icon in the Map Viewer window or from an object pick list) and select the View Manipulation>Reparent Object(s)... option. The Reparent dialog can be launched from a VLAN or sub-interface object.
Figure 13-24 VLAN - Reparent Objects Window
Step 2 Select a parent object from the list of VLAN objects displayed under the specific domain in the VLAN view.
Step 3 Choose Apply.
Deleting VLAN objects
Note A VLAN or sub-interface object can be deleted only if it is in the decommissioned state.
To delete an existing VLAN or a sub-interface object, proceed as follows:
Step 1 Choose the VLAN objects you wish to delete within the VLAN view. Refer to the "VLAN View" section for details of the VLAN view.
Step 2 Choose Deployment>Delete Objects. The Deployment Wizard appears with a summary of what will be deleted.
Figure 13-25
Step 3 Choose Finish, and the VLAN object is deleted. If deletion fails, another interface might be currently using the VLAN object, therefore you cannot delete the object.
Note Similarly, a domain can be deleted provided the VLAN and sub-interface objects are decommissioned.
