Configuring the CoA-NAS Interface
Use the following sample configuration to define Change of Authorization (CoA) NAS interface in the RADIUS endpoint.
config
endpoint radius
interface coa-nas
vip-ip ipv4_address vip-port port_number
end
NOTES:
-
endpoint radius : Enter the RADIUS endpoint configuration mode.
-
interface coa-nas : Enter the CoA NAS interface configuration mode. This keyword defines a new interface "coa-nas".
-
vip-ip ipv4_address vip-port port_number : Specify the IP address of the host. ipv4_address must be in standard IPv4 dotted decimal notation.
You can configure a list of VIP-IPs to listen to the inbound CoA or DM requests.
vip-port port_number : Specify the port number of the UDP proxy. By default, the port number is 3799. This default value is used only when the VIP-IP is specified.
ImportantThis configuration allows only port to be specified per IP.
The SMF (udp-pxy) listens to the inbound CoA or DM request messages on these ports, and ACK or NAK messages sent with the respective source IP and port.
