Device discovery and configuration

The switch provides support for LLDP, CDP, and device profiles to enable automatic discovery and configuration of other devices on the network.

Device profiles enable predefined configuration settings to be applied to an interface based on the type of devices that are connected to the interface. When a device of a configured type is connected to an interface, the switch automatically applies the corresponding device profile. Connected devices are identified using LLDP. When the LLDP information on the interface ages out, the profile/role is revoked from the interface. Only devices directly connected to the switch are detected and processed for device profile application.

The following interface setting can be applied on the detection of a matching device type:
  • Untagged VLANs: The VLAN on which untagged packets are classified.*

  • Tagged VLANs: The list of allowed tagged VLANs on the interface.*

  • Policies: The policy associated with a role. This mode is set by the policy command.

  • PoE priority: The PoE priority applied to the interface. Supported values are high, low, and critical.

  • QoS Trust: QoS Trust mode applied to the interface. Supported values are dscp, tos, and none. This mode is set by the qos trust command.

  • Jumbo frames: Enable or disable jumbo frame support for the interface. This mode is set by the MTU command.

*The process for applying the setting depends on how the VLAN interface is configured. See VLAN interfaces.

Figure 1: Example configuration of device deployment

The switch provides simplified deployment of devices, such as access points, IP phones, security cameras, and printers, through the use of a locally configured repository that provides authentication and dynamic port assignment, such as QoS, PoE, and tagged VLANs.
