Any authentication requests to this authentication server must present the correct secret value to gain authentication. Since MAC-based authentication authenticates the device, not the user, and is subject to MAC address spoofing attacks, it should not be considered a secure authentication method. The sources DR registers (that is, encapsulates) and sends multicast data from the source directly to the RP via a unicast routing protocol (number 1 in figure). The allocation mechanism attempts to maximize aggregation, subject to management controls. sFlow Table 18-3 describes how to manage remote network monitoring.
