bandwidth, please select NoLimit.
 Min. Rx Bandwidth: It specifies the guaranteed download bandwidth allocated to the
LAN hosts or applications that match the rate limit rule.
 Max. Tx Bandwidth: It specifies the maximum upload bandwidth allocated to the
LAN hosts or applications that match the rate limit rule.
 Max. Rx Bandwidth: It specifies the maximum download bandwidth allocated to the
LAN hosts or applications that match the rate limit rule.
 Description: It specifies the description of the rate limit rule. It is usually used to
describe the purpose of the rule.
¾ Advanced Options: Click it view and configure advanced parameters. In most cases,
you need not configure them.
¾ Each: If you select this radio button, the Device will assgin the specified bandwidths
to each LAN host or application that matches the rule. For example, if the Min. Tx
Bandwidth is set to 1M and there are 10 LAN hosts match the rule, each host will be
ensured with at least 1M upload bandwidth.
¾ Share: If you select this radio button, all the LAN hosts or applications that match the
rule will share the specified bandwidths. For example, if the Min. Tx Bandwidth is set
to 1M and there are 10 LAN hosts match the rule, the total upload bandwidth
allocated to all the hosts is at least 1M.
 Service Group: It allows you to select a service group to specify the protocol type
(TCP, UDP or ICMP) and ports of the traffic to which the rate limit rule applies. Note
that only the service groups whose Service Type is General Service can be
referenced by the rate limit rules. The default value is Any Service, which means any
protocol type and port.
 Bandwidth Priority: It specifies the bandwidth priority of the traffic to which the rate
limit rule applies. There are three options: Low, Mid, and High. The Device will
preferentially assign idle bandwidth to the traffic with higher priority; when the network
is busy, the Device will firstly ensure the guaranteed bandwidth for the traffic with high
priority.
 Bind to: It specifies an Internet connection to which the rate limit rule is bound.
 Schedule: It specifies a schedule to restrict when the rate limit rule is in effect. The
default value is Always, which means the rate limit rule is in effect always. Note that
after the selected schedule has expired, the rule will be in effect always.
¾ Edit Schedule: Click it to go to the Security > Schedule page to add, view, modify or
delete schedules.
¾ Edit Address Group: Click it to go to the Security > Address Group page to add,
