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 Enables the SNMP agent.

• SNMP Community Specify the SNMP community

string. It is required to authenticate access to

Management Information Base (MIB) objects and

functions as an embedded password. The device

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

default SNMP Community is public.

• Contact Specify the contact who should be notified in

case of emergency.

• Location Specify the physical location of the device.

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.

• Host Name Enter the host name of the DDNS server.

• Username Enter the username of the DDNS account.

• Password Enter the password of the DDNS account.
