Management VLANs Chapter 8 Configuring VLANs Changing the Management VLAN for a New Switch If you add a new switch to an existing cluster and the cluster is using a management VLAN other than the default VLAN 1, the command switch automatically senses that the new switch has a different management VLAN and has not been configured. The command switch issues commands to change the management VLAN on the new switch to match the one in use by the cluster. This automatic change of the VLAN only occurs for new, out-of-box switches that do not have a config.text file and for which there have been no changes to the running configuration. Before a new switch can be added to a cluster, it must be connected to a port that belongs to the cluster management VLAN. If the cluster is configured with a management VLAN other than the default, the command switch changes the management VLAN for new switches when they are connected to the cluster. In this way, the new switch can exchange CDP messages with the command switch and be proposed as a cluster candidate. Note For the command switch to change the management VLAN on a new switch, there must have been no changes to the new switch configuration, and there must be no config.text file. Because the switch is new and unconfigured, its management VLAN is changed to the cluster management VLAN when it is first added to the cluster. All ports that have an active link at the time of this change become members of the new management VLAN. For information about the roles management VLANs play in switch clusters, see the "Management VLAN" section on page 5-18. Changing the Management VLAN Through a Telnet Connection Before you start, review the "Management VLANs" section on page 8-3. Beginning in privileged EXEC mode on the command switch, follow these steps to configure the management VLAN interface through a Telnet connection: Step 1 Step 2 Command configure terminal cluster management-vlan vlanid Step 3 show running-config Purpose Enter global configuration mode. Change the management VLAN for the cluster. This ends your Telnet session. Move the port through which you are connected to the switch to a port in the new management VLAN. Verify the change.
