Netgear XCM8810 - 8800 SERIES 10-SLOT CHASSIS SWITCH ハードウェアマニュアル

NETGEAR 8800 switches are also capable of sending RADIUS accounting information. You can 
configure RADIUS accounting servers to be the same as the authentication servers, but this is 
not required.

Terminal Access Controller Access Control System Plus (TACACS+) is a mechanism for 
providing authentication, authorization, and accounting on a centralized server, similar in function 
to the RADIUS client. The NETGEAR 8800 version of TACACS+ is used to authenticate 
prospective users who are attempting to administer the switch. TACACS+ is used to 
communicate between the switch and an authentication database.

You cannot use RADIUS and TACACS+ at the same time.

Denial of Service

You can configure the NETGEAR 8800 to protect your NETGEAR switches in the event of a 
denial of service attack. During a typical denial of service attack, the CPU on the switch gets 
flooded with packets from multiple attackers, potentially causing the switch to fail. To protect 
against this type of attack, you can configure the software so that when the number of 
packets received is more than the configured threshold limit of packets per second, a 
hardware ACL is enabled.
