AirRouter User Guide
Traffic Shaping
Wireless Traffic shaping is dedicated to upstream and
downstream bandwidth control while looking from the
client (connected on the Ethernet interface) perspective.
The traffic can be limited at the AirRouter in the upload
and download direction based on a user defined rate limit.
This is layer 3 QoS.
Enable Traffic Shaping
This option will enable
bandwidth control on the device.
•
Incoming Traffic Limit
Specify the maximum
bandwidth value (in kilobits per second, Kbps) for traffic
passing from the wireless interface to the Ethernet
interface.
•
Incoming Traffic Burst
Specify the data volume (in
kilobytes) to which the Incoming Traffic Limit will not be
effective afterwards data connection is initiated.
•
Outgoing Traffic Limit
Specify the maximum
bandwidth value (in kilobits per second, Kbps) for traffic
passing from the Ethernet interface to the wireless
interface.
•
Outgoing Traffic Burst
Specify the data volume (in
kilobytes) to which the Outgoing Traffic Limit will not be
effective after data connection is initiated.
Services
The Services tab covers the configuration of system
management services SNMP, SSH, System Log and Ping
Watchdog.
Ping Watchdog
Ping Watchdog sets the AirRouter 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 AirRouter 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
Enables the Ping Watchdog tool.
•
IP Address To Ping
Specify the IP address of the target
host which to be monitored by the 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 the first ICMP echo requests are 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 a 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. The AirRouter contains an SNMP
agent which allows it to communicate to SNMP manage
applications for network provisioning.
