Using Dynamic Interfaces for Management

Information About Using Dynamic Interfaces for Management

You can access the controller with one of its dynamic interface IP addresses. While wired computers can have only CLI access with the dynamic interface of the WLC, wireless clients have both CLI and GUI access with the dynamic interface.

A device, when the management using dynamic interfaces is disabled, can open an SSH connection, if the protocol is enabled. However, you are not prompted to log on. Additionally, the management address remains accessible from a dynamic interface VLAN, unless a CPU ACL is in place. When management using dynamic interface is enabled along with CPU ACL, the CPU ACL has more priority.

The following are some examples of management access and management access using dynamic interfaces, here the management VLAN IP address of the Cisco WLC is 209.165. 201.1 and dynamic VLAN IP address of the Cisco WLC is 209.165. 202.129:
  • Source wired client from Cisco WLC's dynamic interface VLAN accesses the management interface VLAN and tries for management access. This is an example of management access.
  • Source wired client from Cisco WLC's management interface VLAN accesses the dynamic interface VLAN and tries for management access. This is an example of management using dynamic interface.
  • Source wired client from Cisco WLC's dynamic interface VLAN accesses the dynamic interface VLAN tries and tries for management access. This is an example of management using dynamic interface.
  • Source wired client from Layer 3 VLAN interface accesses the dynamic interface or the management interface and tries for management access. This is an example of management using dynamic interface.

Here, management is not the management interface but the configuration access. If the Cisco WLC configuration is accessed from any other IP address on the Cisco WLC other than the management IP, it is management using dynamic interface.

Configuring Management using Dynamic Interfaces (CLI)

Enable or disable management using dynamic interfaces by entering this command:

config network mgmt-via-dynamic-interface { enable | disable}
