Chapter 3: Using EdgeOS
EdgeRouter
™
Lite User Guide
Ubiquiti Networks, Inc.
Telnet Server
Enable
Disabled by default. This option allows Telnet
access to the EdgeRouter for remote configuration
by command line. Telnet is not a secure form of
communication, so we recommend SSH. See
“Command
Line Interface” on page 38
for more information.
Port
Specify the TCP/IP port of the Telnet server. The
default is
23
.
System Log
Every logged message contains at least a system time and
host name. Usually a specific service name that generates
the system event is also specified within the message.
Messages from different services have different contexts
and different levels of detail. Usually error, warning, or
informational system service messages are reported;
however, more detailed debug level messages can also
be reported. The more detailed the system messages
reported, the greater the volume of log messages
generated.
Log to remote server
This option allows the EdgeRouter
to send system log messages to a remote server. Enter
the remote host IP address and TCP/IP port that should
receive the system log (syslog) messages.
514
is the
default port for the commonly used, system message
logging utilities.
Note:
Properly configure the remote host to receive
syslog protocol messages.
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 EdgeRouter 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:
Enable
Disabled by default. This option activates the
SNMP agent.
SNMP community
Specify the SNMP community string.
It is required to authenticate access to MIB (Management
Information Base) 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 is
public
.
Contact
Specify the contact who should be notified in
case of emergency.
Location
Specify the physical location of the EdgeRouter.

Configuration Management & Device
Maintenance
The controls in this section manage the device
configuration routines and firmware maintenance.
Back Up Config
We recommend that you back up your current system
configuration before updating the firmware or uploading
a new configuration.
Download backup config file
Click
Download
to
download the current system configuration file.
Note:
We strongly recommend that you save the
configuration file in a secure location because it
includes confidential information. The user login
passwords are encrypted; however, other passwords
and keys (such as those used for VPN, BGP,
authentication, and RADIUS) are stored in plain text.
