Chapter 3: AirOS™ AirRouter User Guide
The SNMP Agent provides an interface for device
monitoring using the Simple Network Management
Protocol (an application layer protocol that facilitates the
exchange of management information between network
devices). SNMP Agent allows network administrators to
monitor network performance, find and solve network
problems. For the purpose of equipment identification,
it is always a good idea to configure SNMP agents with
contact and location information:
Enable SNMP Agent Enables the SNMP Agent.
•
SNMP Community Specify the SNMP community
string. It is required to authenticate access to MIB
objects and functions as an embedded password. The
device supports a Read-only community string that
gives read access to authorized management stations to
all the objects in the MIB except the community strings,
but does not allow write access. The AirRouter supports
SNMP v1. The default SNMP Community is public.
• Contact Specify the contact who that should be
notified in case an emergency situation arises.
• Location Specify the physical location of the device.
Web Server
The following Web Server parameters can be set:
Use Secure Connection (HTTPS) If checked Web server
will use secure HTTPS mode. HTTPS mode is unchecked by
default.
• Secure Server Port Defines the Web Server TCP/IP port
Use Secure Connection (HTTPS) is enabled.
Server Port Web Server TCP/IP port setting while using
HTTP mode.
Session timeout Specifies the maximum timeout before
the session expires. Once a session expires, you must login
again using the username and password.
SSH Server
The following SSH Server parameters can be set:
Enable SSH Server This option enables SSH access to the
AirRouter.
• Server Port SSH service TCP/IP port setting.
•
Enable Password Authentication When enabled, you
must authenticate using Administrator credentials in
order to grant SSH access to the device, otherwise an
Authentication Key will be required.
•
Authorized Keys Click Edit to import a public key file
working to get SSH access to the device instead of using
an admin password. Click Browse to locate and select
the key file, then click Import. Click Save to save your
changes or Close to discard your changes.
Telnet Server
The following Telnet Server parameters can be set:
Enable Telnet Server This option activates the Telnet
access to the AirOS Device.
Server Port Telnet service TCP/IP port setting.
NTP Client
The Network Time Protocol (NTP) is a protocol for
synchronizing the clocks of computer systems over
packet-switched, variable-latency data networks. It can
be used to set the AirRouter system time. System Time
is reported next to the every System Log entry while
registering system events if the Log option is enabled.
Enable NTP Client Enables the AirRouter to obtain the
system time from a time server on the Internet.
•
NTP Server Specify the IP address or domain name of
the NTP Server.
System Log
Enable Log This option enables the registration routine
of the system log messages. By default it is disabled.
•
Enable Remote Log Enables the syslog remote sending
function while System log messages are sent to a
remote server specified in the Remote Log IP Address and
Remote Log Port fields.
- Remote Log IP Address The host IP address where
syslog messages should be sent. Remote host should
be configured properly to receive syslog protocol
messages.
