Ping WatchDog
The ping watchdog sets the AirOS v5.3 Device to continuously ping a user-defined IP address
(it can be the internet gateway for example). If it is unable to ping under the user defined
constraints, the AirOS device will automatically reboot. This option creates a kind of "fail-
proof" mechanism.
Ping Watchdog is dedicated for continuous monitoring of the particular connection to remote
host using the Ping tool. The Ping works by sending ICMP “echo request” packets to the target
host and listening for ICMP “echo response” replies. If the defined number of replies is not
received, the tool reboots the device.
Enable Ping Watchdog: control will enable Ping Watchdog Tool.
IP Address To Ping: specify an IP address of the target host which will be monitored by
Ping Watchdog Tool.
Ping Interval: specify time interval (in seconds) between the ICMP “echo
requests” are sent by the Ping Watchdog Tool. The default value is 300
seconds.
Startup Delay: specify initial time delay (in seconds) until first ICMP “echo
request” is sent by the Ping Watchdog Tool. The default value is 300
seconds.
The value of Startup Delay should be at least 60 seconds as the network
interface and wireless connection initialization takes considerable amount of time
if the device is rebooted.
Failure Count to Reboot: specify the number of ICMP “echo response”
replies. If the specified number of ICMP “echo response” packets is not
received continuously, the Ping Watchdog Tool will reboot the device. The default value is 3.
SNMP Agent
Simple Network Monitor Protocol (SNMP) is used in network management
systems to monitor network-attached devices for conditions that warrant
administrative attention. AirOS contains an SNMP agent, which allows it to
communicate to SNMP manage applications for network provisioning.
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: control will enable SNMP Agent.
SNMP Community: specify SNMP community string. It is required to authenticate access to MIB objects and functions as 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. AirOS supports SNMP v1. The default SNMP
Community is ”public”.
Contact: specify the identity or the contact who should be contacted in case a emergency situation arise.
Location: specify the physical location of the device.
Web Server
Web Server: the following AirOS v5.3 Device Web Server parameters can be set
there:
Use Secure Connection (HTTPS): If checked Web server will use secure
HTTPS mode. HTTPS mode is unchecked by default.
Secure Server Port: Web Server TCP/IP port setting while using HTTPS
mode.
Server Port: Web Server TCP/IP port setting while using HTTP mode.
Session timeout: specifies the maximum timeout before the session
expires. Once session expires you must login using device’s credentials to do
changes or see Main Page.
