https://NOCIPADDRESSORHOSTNAMEand click save. - Reboot the device if necessary for devices like cnPilot R200P/R201P and PMP Devices
- Device will come to the on boarding queue in the cnMaestro Home → On board Devices → On board page and the user can approve the device
Claim Through Static URL with Cambium ID and on Boarding key
In order to claim the devices using the static url with cambium id and on boarding key please follow the below steps
- Login to NOC server using default username and password (admin/admin) or the Username and Password set by the Administrator at the time of installation
- Navigate to Home → On board Devices → Claim from Device page

Zero touch on boarding using DHCP option 43
In order to claim the devices using DHCP option 43 user needs to follow the below steps
- Configure the Linux or windows DHCP server to send the options 43 and 60 to the Cambium Devices. A Cambium cnMatrix switch is also an option. Please follow the section for DHCP Configuration
- For claiming devices through this method user need not specify the static url in the device as the device obtains this url from DHCP option 43
- User need not specify anything else in the device as this is Zero touch on board
- Device will come to the on boarding queue in the cnMaestro Home → On board Devices → On board page and the user can approve the device
Zero touch on boarding using DHCP option 15
In order to claim the devices using DHCP option 15 user needs to follow the following steps
- Configure the Linux or windows DHCP server to send the options 15 to the Cambium Devices. A Cambium cnMatrix switch is also an option. Please follow the section for DHCP Configuration
- For claiming devices through this method user need not specify the static url in the device as the device obtains this url from DHCP option 15 (cnmaestro.companyname.com)
- User need not specify anything else in the device as this is Zero touch on board
- Device will come to the on boarding queue in the cnMaestro Home → On board Devices → On board page and the user can approve the device
Note :- For DHCP options to work properly on the already deployed cnPilot R200P/R201P devices , please reset the devices. Before resetting take a backup of the configuration and restore it once the device is reset and comes back online.
For all other device types just make sure that no cnMaestro static url is configured in the device for the DHCP options to work fine.
Claim Through MAC Address
In order to claim through mac address , please follow the below steps
- Login to NOC server using default username and password (admin/admin) or the Username and Password set by the Administrator at the time of NOC server installation
- Navigate to Home → On board Devices → Claim from cnMaestro
- Select the Device type for which on boarding is to be done and provide the MAC Address in the combo box and click the Claim Devices button.
Multiple MAC Addresses of same device type can be claimed using "," separator between MAC Addresses or by entering them in the new line
Note :- Before claiming through MAC Address user needs to specify the static url in the device gui as mentioned in section 2.1 . Even if the device type is selected wrong during claim no need to worry . If the MAC Address is of the correct device , when the device contacts the server it will provide the server with the correct device type
Order of Device Discovery
The device discovery order is as follows in cnMaestro NOC Server and if any of the options is not configured the discovery method will fallback to the next option
- Static cnMaestro URL
- Option 43
- Option 15
- cloud.cambiumnetworks.com
DHCP Configuration
Linux DHCP Options (ISC-DHCP-Server)
A DHCP Server can be used to configure the IP Address, Gateway, and DNS servers for Cambium devices. If you administer the DHCP Server, you can also configure DHCP Options that will tell the devices how to access the cnMaestro (so the URL doesn’t need to be set on each device). Cambium devices support DHCP Options 43 and 15 for setting the cnMaestro On-Premises URL.
Using DHCP Option 43
DHCP Option 43 returns the cnMaestro On-Premises URL as a Vendor-Specific Option. DHCP Option 43 is returned in tandem with DHCP Option 60 (the Vendor Class Identifier, or VCI). The VCI for the individual Cambium products is listed below.
| Product | VCI (DHCP Option 60) |

Typically, Option 43 will be the preferred mechanism to configure the cnMaestro URL. Example configuration for the ISC DHCP Server is presented below (from the /etc/dhcp/dhcpd.conf file).
option option-43 code 43 = string;
# ePMP Devices
class "Cambium" {
match if option vendor-class-identifier = "Cambium";
# DHCP server MUST return the device’s Vendor Class back, in the offer.
option vendor-class-identifier "Cambium";
# cnMaestro On-Premises IP is 192.168.0.100
option option-43 "https://192.168.0.100";
}
# WiFi Devices
class "Cambium-WiFi-AP" {
match if option vendor-class-identifier = "Cambium-WiFi-AP";
option vendor-class-identifier "Cambium-WiFi-AP";
option option-43 "https://192.168.0.100";
}
# cnPilot R200P Devices
class "Cambium-cnPilot R200P" {
match if option vendor-class-identifier = "Cambium-cnPilot R200P";
option vendor-class-identifier "Cambium-cnPilot R200P";
option option-43 "https://192.168.0.100";
}
# cnPilot R201P Devices
class "Cambium-cnPilot R201P" {
match if option vendor-class-identifier = "Cambium-cnPilot R201P";
option vendor-class-identifier "Cambium-cnPilot R201P";
option option-43 "https://192.168.0.100";
}
# PMP Devices
class "Cambium PMP 450 AP" {
match if option vendor-class-identifier = "Cambium PMP 450 AP";
option vendor-class-identifier "Cambium PMP 450 AP";
option option-43 "https://192.168.0.100";
}
Using DHCP Option 15
DHCP Option 15 allows the device to derive the cnMaestro URL from the domain name. For example, if the domain name in DHCP Option 15 is mycompany.com, then the device will try to access the cnMaestro server at cnmaestro.mycompany.com (essentially the string “cnmaestro” is prepended to the domain). The domain itself, and the IP address of cnMaestro, must be configured in the DNS server for this to work correctly.
Sample configuration for the ISC DHCP Server is presented below (from the /etc/dhcp/dhcpd.conf file).
option domain-name "mycompany.com";
Note :- User needs to map the cnmaestro.mycompany.com to the proper NOCSERVERIPADDRESS in the DNS server for on boarding to work properly
