| Code | Description | Notes/Example |
|---|---|---|
| 61 | Client Identifier | The base MAC address of the AP. Example: 8c:9c:d8:ca:73:20 |
| 60 | Vendor Class Identifier | The option 60 value sent by instant-based APs. Example: ArubaInstantAP |
The standard and vendor-specific DHCP options that are requested by AOS-8 instant-based APs in discovery and request packets tells the DHCP server which options are supported and can be returned to the APs.

Standard return options
The standard DHCP options that can be returned to AOS-8 instant-based APs from a DHCP server in offer and acknowledgement packets:
| Code | Description | Format | Notes/Example |
|---|---|---|---|
| 1 | Subnet Mask | IP Address | The subnet mask assigned by the DHCP server. Example: 255.255.255.0 |
| 3 | Router | IP Address | The default gateway assigned by the DHCP server. Example: 10.0.2.1 |
| 6 | Domain Name Server | IP Address | A list of DNS servers assigned by the DHCP server (in order of preference). Example: 10.0.2.2 |
| 15 | Domain Name | String | The domain name assigned by the DHCP server. Example: hpe.com |
| 42 | Network Time Protocol Servers | String | IP addresses or FQDNs of one or more NTP servers. Example: 10.0.2.50 |
By default, the AP tries to connect to pool.ntp.org to synchronize time. The NTP server can also be provisioned through the DHCP option 42. If the NTP server is configured, it takes precedence over the DHCP option 42 provisioned value. The NTP server provisioned through the DHCP option 42 is used if no server is configured. The default server pool.ntp.org is used if no NTP server is configured or provisioned through DHCP option 42.
Vendor-specific return options
The vendor-specific DHCP option 148 can be returned to AOS-8 instant-based APs for Zero Touch Provisioning (ZTP) via an HTTP proxy server when Activate or Central are accessible through the proxy.
HTTP Proxy
| Code | Description | Format | Notes/Example |
|---|---|---|---|
| 148 | Proxy Server Information | String | HTTP proxy server IP/FQDN, Port, Username and Password.
|
| 60 | Vendor Class Identifier | String | Must be applied with option 148. Mandatory Value: ArubaInstantAP |
