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.

    Important

    This 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.
