Tech Note – RADIUS Troubleshooting
Overview
RADIUS Authentication, Authorisation and Accounting (AAA) is a core component of the
amigopod platform and therefore being able to effectively troubleshoot any authentication
issues between Access Controllers (RADIUS NAS devices) and the amigopod is essential.
By default amigopod is configured to communicate RADIUS traffic on the following ports:
o Authentication transaction on UDP port 1812
o Accounting transactions on UDP port 1813
o RFC 3576 transactions on UDP port 3799
The inbuilt firewall rules that protect the amigopod kernel are automatically provisioned to
allow traffic to flow to and from these ports.
Basic Configuration
When configuring your network environment you must ensure that your Access Controller’s
RADIUS server definitions for both Authentication and Accounting are configured to match
the above port settings. If your deployment demands that this default ports be changed from
1812 and 1813 these can be modified through the amigopod web interface under RADIUS
Services
