Advanced Configuration

Ether Type  Specifies the packet’s Ethernet type.

Use the Add to List button to add the configured MAC Based ACLs to the MAC Based ACL Table at the bottom of the screen.

Security > ACL Binding

When an ACL is bound to an interface, all the ACE rules that have been defined are applied to the selected interface. Whenever an ACL is assigned on a port, LAG or, VLAN, flows from that ingress interface that do not match the ACL are matched to the default rule, which is Drop unmatched packets.

Security > ACL Binding

Interface  Indicates the interface to which the ACL is bound.

ACL Name  Indicates the ACL which is bound to the interface.

Use the Add to List button to add the ACL Binding configuration to the ACL Binding Table at the bottom of the screen.

Security > RADIUS

Remote Authorization Dial-In User Service (RADIUS) servers provide additional security for networks. RADIUS servers provide a centralized authentication method for web access.

Security > RADIUS

IP Address  The Authentication Server IP address.

Priority  The server priority. The possible values are 0–65,535, where 1 is the highest value. The RADIUS Server priority is used to configure the server query order.

Authentication Port  Identifies the authentication port. The authentication port is used to verify the RADIUS server authentication. The authenticated port default is 1812.

Number of Retries  Defines the number of transmitted requests sent to RADIUS server before a failure occurs. The possible field values are 1–10. The default value is 3.

Timeout for Reply  Defines the amount of the time in seconds the device waits for an answer from the RADIUS server before retrying the query, or switching to the next server. The possible field values are 1–30. The default value is 3.

Dead Time  Defines the amount of time (minutes) that a RADIUS server is bypassed for service requests. The range is 0–2000. The Dead Time default is 0 minutes.

Key String  Defines the default key string used for authenticatingandencryptingallRADIUScommunications between the device and the RADIUS server. This key must match the RADIUS encryption.

Source IP Address  Defines the source IP address that is used for communication with RADIUS servers.

Usage Type  Specifies the RADIUS server authentication type. The default value is Login. The possible field values are:

•• Login  Indicates that the RADIUS server is used for authenticating user name and passwords.
