4.6.3 Start/Stop of ARDA
Start of ARDA is executed by the following command:
ARDA start
In order to stop ARDA, execute the following command in "config" mode:
stop (daemon|clear)
Example:

If "stop" command is executed with clear parameter, the device will clear its part of
the system configuration prior to quitting CS.
4.6.4 Filters
In many participating in the configuration parameters of the device filters are
used. Filters are represented by two classes of objects:
 Access lists (access-list)
 Prefixes lists (prefix-list)
Access lists consist of a set of operators. Each operator consists of a range of
IP-addresses and deny or permit command. The range of addresses is set as
<value> <mask for insignificant bits>. The object to be filtrated has its basic
parameter in the same format (IP-address, subnet etc). To make a decision
whether the object corresponds with a list, each operator from the list is
consequently applied to the basic parameter of the object until this parameter
satisfies the condition. When a right condition is met, the decision is made
according to the record in the command of the operator (deny or permit).
In ARDA there are three types of access lists:
 Standard. Is identified by numbers 1-99 or 1300-1999 and is used to analyze
one parameter of filtration object.
 Extended. Is identified by numbers 100-199 or 2000-2699 and is used to
analyze two parameters of filtration object (for example, source address and
destination address).
