The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include such as number of
packets received, node port status etc. A Management Information Base (MIB) is a collection of
managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing
these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The
manager issues a request and the agent returns responses using the following protocol operations:
Get - Allows the manager to retrieve an object variable from the agent.
GetNext - Allows the manager to retrieve the next object variable from a table or list within an
agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it
initiates a Get operation, followed by a series of GetNext operations.
Set - Allows the manager to set values for object variables within an agent.
Trap - Used by the agent to inform the manager of some events.

The following table describes the labels in this screen.
20.7
Wake On LAN Screen
Wake On LAN (WoL) allows you to remotely turn on a device on the network, such as a computer,
storage device or media server. To use this feature the remote hardware (for example the network
adapter on a computer) must support Wake On LAN using the “Magic Packet” method.
You need to know the MAC address of the remote device. It may be on a label on the device.

SNMP Settings
Server Port
The SNMP agent listens on port 161 by default. If you change the SNMP server port to a
different number on the EMG2926-Q10A, for example 8161, then you must notify
people who need to access the EMG2926-Q10A SNMP agent to use the same port.

TR069 Screen
TR-069 defines how Customer Premise Equipment (CPE), for example your ZyXEL Device, can be
managed over the WAN by an Auto Configuration Server (ACS). TR-069 is based on sending
Remote Procedure Calls (RPCs) between an ACS and a client device. RPCs are sent in Extensible
Markup Language (XML) format over HTTP or HTTPS.

Wake On LAN over WAN
Settings
Enable WOL over WAN
Select this option to have the EMG2926-Q10A forward a WoL “Magic Packet” to
all devices on the LAN if the packet comes from the WAN or remote network
and uses the port number specified in the
Port
field. A LAN device whose
hardware supports Wake on LAN then will be powered on if it is turned off
previously.
Port
Type a port number from which a WoL packet is forwarded to the LAN.
Wake On LAN
Wake MAC Address
Enter the MAC Address of the device on the network that will be turned on.
A MAC address consists of six hexadecimal character pairs.
Start
Click this to have the EMG2926-Q10A generate a WoL packet and forward it to
turn the specified device on.
A screen pops up displaying MAC address error if you input the MAC address
incorrectly.
