in the DHCP network, the administrator needs the MAC address of the UPSLink found on the label
sticker at the bottom of the UPSLink.
4.1.3 Using PPPoE
PPPoE (Point-to-Point Protocol over Ethernet) is a specification for connecting multiple computer
users on an Ethernet LAN (local area network) to a remote site through a modem or similar device.
PPPoE can be used to multiple users the ability to share ADSL, cable modem, or wireless connection
to the Internet.
To use the UPSLink in PPPoE mode, users require a PPPoE account and the necessary equipment
for PPPoE access (i.e. an ADSL modem ). Since the UPSLink provides a PPPoE protocol, it can
access the remote host on the Internet over an ADSL connection. The user will have to set up the user
name and password of the PPPoE account for the UPSLink.
The UPSLink negotiates the PPPoE connection with the PPPoE server whenever it boots up. During
the negotiation, the UPSLink receives the information required for an Internet connection, such as the
IP address, gateway, subnet mask and DNS servers. If the connection is established, the UPSLink will
maintain the connection for as long as possible. If the connection is terminated, the UPSLink will
attempt to make a new PPPoE connection by requesting a new connection.
Note: While in PPPoE mode, all network-related parameters for the UPSLink are to be configured
automatically, including the DNS servers. If the DNS server is not automatically configured, the user
may manually configure the settings by entering the primary and secondary DNS IP addresses.
To
force an automatic configuration of the DNS address, set the primary and secondary DNS IP
addresses to 0.0.0.0 (recommended).
4.2 SNMP configurations
The UPSLink has the SNMP (Simple Network Management Protocol) agent supporting SNMP v1 and
v2c protocols. Network managers like NMS or SNMP Browser can exchange information with UPSLink
and control it.
SNMP protocols include GET, SET, GET–Next, and TRAPs. With these functions, a manager can be
notified of significant events (TRAPs), query a device for more information (GET, GET-Next), and
make changes to the device state (SET). SNMPv2 adds a GET–Bulk function to retrieve tables of
information and security functions.
With the SNMP configuration panel, the user can configure MIB-II System objects, access control
settings and Trap receiver settings. The manager configured in this menu can perform both
information exchange and action control. Figure 0-2 is the SNMP configuration screenshot on the web
interface.
