Port Security Modes - HP A6600 Configuration Manual

Port security modes

Port security supports the following categories of security modes:
MAC learning control—Includes two modes, autoLearn and secure. MAC address learning is
•
permitted on a port in autoLearn mode and disabled in secure mode.
Authentication—Security modes of this category use MAC authentication, 802.1X authentication,
•
or their combinations to implement authentication.
Upon receiving a frame, the port in a security mode searches the MAC address table for the source
MAC address. If a match is found, the port forwards the frame. If no match is found, the port learns the
MAC address or performs authentication, depending on the security mode. If an illegal frame or event is
detected, the port takes the predefined NTK, intrusion protection, or trapping action.
Table 9 describes the port security modes and the security features.

Purpose
Turn off the port security feature
Control MAC address learning
Perform 802.1X authentication
Perform MAC authentication
Perform a combination of MAC
authentication and 802.1X
authentication
TIP:
• userLogin specifies 802.1X authentication and port-based access control.
• macAddress specifies MAC authentication.
• Else specifies that the authentication method before Else is applied first. If the authentication fails,
whether to turn to the authentication method following Else depends on the protocol type of the
authentication request.
• In a security mode with Or, which authentication method to be used depends on the protocol type of the
authentication request.
• userLogin with Secure specifies 802.1X authentication and MAC-based access control.
• Ext indicates allowing multiple 802.1X users to be authenticated and serviced at the same time. A
security mode without Ext allows only one user to pass 802.1X authentication.
Security mode
noRestrictions (the default mode)
In this mode, port security is disabled on the port,
and access to the port is not restricted.
