Assigning SM management IP addressing via

RADIUS

Configuring a RADIUS server

A RADIUS dictionary file is available from the software

site:

www.cambiumnetworks.com/support/pmp/software/

The RADIUS dictionary file

defines

the VSAs and their values and is usually imported into the

RADIUS server as part of

server

and database

setup.

Assigning SM management IP addressing via

RADIUS

Operators may use a RADIUS AAA server to assign management IP addressing to SM modules

(framed IP address). SMs now interpret attributes Framed-IP-Address, Framed-IP-Netmask, and

Cambium-Canopy-Gateway from RADIUS. The RADIUS dictionary file has been updated to

include the Cambium-Canopy-Gateway attribute and is available on the Cambium Software

Support website.

In order for these attributes to be assigned and used by the SM, the following must be true:

• The Canopy system is configured for AAA authentication

• The SM is not configured for DHCP on its management interface. If DHCP is enabled and

these attributes are configured in the RADIUS server, the attributes will be ignored by the

SM.

• The SM management interface must be configured to be publically accessible. If the SM is

configured to have local accessibility, the management interface will still be assigned the

framed addressing, and the SM will become publicly accessible via the assigned framed IP

addressing.

• When using these attributes, for the addressing to be implemented by the SM operators must

configure Framed-IP-Address in RADIUS. If Framed-IP-Address is not configured but

Framed-IP-Netmask and/or Cambium-Canopy-Gateway is configured, the attributes will be

ignored. In the case where only the Framed-IP-Address is configured, Framed-IP-Netmask

defaults to 255.255.0.0 (NAT disabled) / 255.255.255.0 (NAT enabled) and Cambium-

Canopy-Gateway defaults to 0.0.0.0.
