Your Device can act as an SNMP agent, which allows a manager station to manage and monitor
the Device through the network. Use the
SNMP
screen (see
Section 24.5 on page 199
) to
configure through which interface(s) and from which IP address(es) users can use SNMP to
access the Device.
Use the
DNS
screen (
Section 24.6 on page 201
) to configure through which interface(s) and
from which IP address(es) users can send DNS queries to the Device.
Use the
ICMP
screen (
Section 24.7 on page 202
) to set whether or not your Device will respond
to pings and probes for services that you have not made available.
Use the
SSH
screen (
Section 24.8 on page 203
) to configure through which interface(s) and from
which IP address(es) users can use SSH to manage the Device.

What You Need to Know About Remote Management
Remote Management Limitations
Remote management does not work when:
You have not enabled that service on the interface in the corresponding remote management
screen.
You have disabled that service in one of the remote management screens.
The IP address in the
Secured Client IP Address
field does not match the client IP address. If
it does not match, the Device will disconnect the session immediately.
There is a firewall rule that blocks it.
Remote Management and NAT
When NAT is enabled:
Use the Device’s WAN IP address when configuring from the WAN.
Use the Device’s LAN IP address when configuring from the LAN.

The WWW Screen
Use this screen to specify how to connect to the Device from a web browser, such as Internet
Explorer.

SNMP Management Model
An SNMP managed network consists of two main types of component: agents and a manager.
An agent is a management software module that resides in a managed device (the Device). An
agent translates the local management information from the managed device into a form
compatible with SNMP. The manager is the console through which network administrators perform
network management functions. It executes applications that control and monitor managed
devices.
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.
