context <context_name>
radius change-authorize-nas-ip <ipv4/ipv6_address>
end

To identify the subscriber session, use any one of the following attributes.
 If 3GPP2 service is configured the following attribute is used for correlation identifier:
 3GPP2-Correlation-ID: The values should exactly match the 3GPP2-correlation-id of the subscriber
 If 3GPP service is configured the following attributes are used for different identifiers:
 3GPP-IMSI: International Mobile Subscriber Identification (IMSI) number should be validated and
