SNMP Agent
Simple Network Monitor Protocol (SNMP) is an
application layer protocol that facilitates the exchange
of management information between network
devices. Network administrators use SNMP to monitor
network-attached devices for issues that warrant
attention.
The device contains an SNMP agent, which does the
following:
• Provides an interface for device monitoring using SNMP
• Communicates with SNMP management applications
for network provisioning
• Allows network administrators to monitor network
performance and troubleshoot network problems
For the purpose of equipment identification, configure the
SNMP agent with contact and location information:
SNMP Agent

string. It is required to authenticate access to
Management Information Base (MIB) objects and

supports a read-only community string; authorized
management stations have read access to all the objects
in the MIB except the community strings, but do not
have write access. The device supports SNMP v1. The

Dynamic DNS
Domain Name System (DNS) translates domain names
to IP addresses; Each DNS server on the Internet holds
these mappings in its respective DNS database. Dynamic
Domain Name System (DDNS) is a network service that
notifies the DNS server in real time of any changes in the
device’s IP settings. Even if the device’s IP address changes,
you can still access the device through its domain name.
Dynamic DNS
If enabled, the device allows
communications with the DDNS server.
