ONFIG
It is used to set the priority part of the LACP system ID. LACP will only aggregate together the ports whose peer
link partners are all on a single system. Each system supports LACP will be assigned a globally unique System
Identifier for this purpose. A system ID is a 64-bit field comprising a 48-bit MAC Address and 16-bit priority
value.

Parameter Description
System Priority
The System Priority can be set by the user. Its range is from 1 to
65535. Default: 32768.
Hash Method
DA+SA, DA and SA are three Hash methods offered for the Link
Aggregation of the switch. Packets will decide the path to transmit
according to the mode of Hash you choose.
Default: DA and SA
4.17 802.1x Configuration
802.1x port-based network access control provides a method to restrict users to access network resources via
authenticating user’s information. This restricts users from gaining access to the network resources through a
802.1x-enabled port without authentication. If a user wishes to touch the network through a port under 802.1x
control, he (she) must firstly input his (her) account name for authentication and waits for gaining
authorization before sending or receiving any packets from a 802.1x-enabled port.
Before the devices or end stations can access the network resources through the ports under 802.1x control,
the devices or end stations connected to a controlled port send the authentication request to the authenticator,
the authenticator pass the request to the authentication server to authenticate and verify, and the server tell the
authenticator if the request get the grant of authorization for the ports.
According to IEEE802.1x, there are three components implemented. They are Authenticator, Supplicant and
Authentication server shown in Fig. 4-1.
Supplicant:
It is an entity being authenticated by an authenticator. It is used to communicate with the Authenticator PAE
(Port Access Entity) by exchanging the authentication message when the Authenticator PAE request to it.
Authenticator:
An entity facilitates the authentication of the supplicant entity. It controls the state of the port, authorized or
unauthorized, according to the result of authentication message exchanged between it and a supplicant PAE.
The authenticator may request the supplicant to re-authenticate itself at a configured time period. Once start
re-authenticating the supplicant, the controlled port keeps in the authorized state until re-authentication fails.
