Q:

What is auto device detection and how it works with Aruba AP



A:

The auto device detection and configuration detects a directly connected Aruba AP dynamically and applies predefined configurations to ports on which the Aruba AP is detected.

You can create port configuration profiles, associate them to a device type, and enable or disable a device type. The only device type supported is aruba-ap and it is used to identify all the Aruba APs.

When a configured device type is connected on a port, the system automatically applies the corresponding port profile. Connected devices are identified using LLDP. When the LLDP information on the port ages out, the device profile is removed.

By default, the device profile feature is disabled. When you enable the device profile support for a device type, if no other device profile is mapped to the device type, the default device profile default-ap-profile is associated with the device type. You can modify the AP default device profile configuration but you cannot delete it. The default-ap-profile command supports only the AP device type.

Requirements

 

Only APs directly connected to the switch will be detected.

Limitations

 

  • Only one device type is supported, aruba-ap, and it is used to identify all the Aruba APs.

  • You can modify the configuration parameters of the default profile, default-ap-profile, but you cannot

    delete it or change its name.

  • The maximum value for poe-max-power is 33 W.

  • If the port was part of any protocol VLANs prior to the device profile application, those VLANs will not be removed while applying the device profile.

  • The egress-bandwidth is only supported for devices running on:

    • Aruba 2930F Switch Series

    • Aruba 2930M Switch Series

 

For testing i have used Switch 2930F

configuration in the switch:

Create a device-profile and configure it as per the requirement:


 Device Profile Configuration

 Configuration for device-profile : default-ap-profile
  untagged-vlan      : 50
  tagged-vlan        : 51-55
  ingress-bandwidth  : 100%
  egress-bandwidth   : 100%
  cos                : None
  speed-duplex       : auto
  poe-max-power      : Class/LLDP
  poe-priority       : high
  allow-jumbo-frames : Disabled
  allow-tunneled-node: Enabled

Apply this configuration to the interface as below,

Aruba-2930F-8G-PoEP-2SFPP(config)# interface 8
Aruba-2930F-8G-PoEP-2SFPP(eth-8)# device-profile name default-ap-profile​

The configuration of the interface as below,

interface 8
   untagged vlan 1

Note:

Only if Aruba AP is detected via LLDP the above profile will be applied and the AP wil receive IP from the configured VLAN. If you connect any other device it doesn't get an IP address as the interface doesn't have any configuration.
