Rule Name
The name of the rule that is set by you. This name can contain any alphanumeric character, underscore, hyphen, or period. It may be from 1 to 20 characters and cannot contain any blanks.

Choose from the following rules:

  • Active connections (total)
    Based on the total number of active connections for the port. You may want to use rules based on the total active connections on a port if your servers get overloaded and start throwing packets away. Certain Web servers will continue to accept connections even though they do not have enough threads to respond to the request. As a result, the client requests time out and the customer going to your Web Site is not served. Use rules based on active connections to balance capacity within a pool of servers.
  • Always True
    An always true rule will always be selected, unless all the servers associated with it are down. For this reason, it should typically be set at a lower priority than other rules. (Think of it as an else statement in programming logic.)
Priority (optional)
An integer representing the order in which rules are reviewed. If no priority is given to the first rule you set, by default it is given a priority value of 1 and evaluated first. The next rule is then given a priority value of 11 and evaluated second, (last priority value + 10, in this case 1 + 10), third rule = 21, fourth rule = 31, and so forth. The rules are evaluated in numerical order, lower numbers taking precedence over higher ones.

Begin Range
The lower value in the range used to determine whether or not the rule is true. If you are adding a rule based on active connections, then the begin range is an integer. The default is 0.

You do not have to specify a begin range for an always true, shared bandwidth, type of service or content rule.

End Range
The upper value in the range used to determine whether or not the rule is true. If you are adding a rule based on active connections, then the end range is an integer. The default is 2 to the 32nd power minus 1.

You do not specify an end range for an always true, shared bandwidth, type of service (TOS) or content rule.

Level to evaluate (Valid only for Total connections, and Active connections rules.)
Choose between evaluating all of the servers on the port or only the servers on the rule.
