Creating a device identity and associating a device type

Procedure

Create a device identity using the command:
```
switch# device-identiy name <DEVICE-NAME>
```
Aruba switches detect devices automatically using LLDP. Configure one of the following TLV values in LLDP packet to identify a device:
- OUI (Type 127): The Organizationally Unique Identifier (OUI) is a 24-bit globally unique assigned number used to identify LLDP device. The default OUI 000000 indicates that device-identity will not use LLDP to identify device.
```
switch(config)# device-identity name <DEVICE-NAME> lldp oui <MAC-OUI> sub-type <SUBTYPE>
```
- System Name (Type 5): The system name field is an alpha-numeric string that indicates the assigned name of the system. The maximum supported length is 128 characters.
```
switch(config)# device-identity name <DEVICE-NAME> lldp sys-name <SYSTEM-NAME>
```
- System Description (Type 6): The system description field is an alpha-numeric string that is a textual description of the network entity. The maximum supported length is 128 characters.
```
switch(config)# device-identity name <DEVICE-NAME> lldp sys-desc <SYSTEM-DESCRIPTION>
```
Examples:
To add new device on switch:
```
switch(config)# device-identity name ArubaOUI lldp oui 000b86 sub-type 2
```
To remove device from switch:
```
switch(config)# no device-identity name ArubaOUI
```
To configure system name on switch:
```
switch(config)# device-identity name ArubaName lldp sys-name Aruba
```
To configure system description on switch:
```
switch(config)# device-identity name ArubaDesc lldp sys-desc "Aruba Cloud Managed Device"
```
The order of precedence of TLV used to detect a device is as follows:
- Hardcoded Aruba OUI
- System Name (type 5)
- System Description (type 6)
- MAC OUI (type 127)
A case-insensitive substring match is carried out on the received LLDP TLV value for system name and description to identify a device. One or more device identities can be associated with a single device profile.

NOTE: Configuring a TLV value to a device identity will overwrite the previous value.

Show device identity configuration:

switch(config)# show device-identity lldp
