- By default, the switch uses the local IP interface of the VLAN as the source-ip, in which the RADIUS server resides OR it uses the local IP interface of the VLAN as the source-ip through which the packets are routed to reach the RADIUS server, if it is on a different subnet. This is the case whether source-ip in the radius server host configuration, configured or not, does not matter.
- If a source-IP is configured and use any other VLAN IP interface as source-ip, the switch will continue to use the default source IP, even if the sourceip-flag is enabled or not.
- If we use the CLIP address (Loopback IP) as source-ip but sourceip-flag is not enabled, it will still use the default source IP.
- If we use the CLIP address and sourceip-flag is also enabled, then the switch will use the CLIP address as the source-ip.
