Problems solved by technology

The disadvantage of this method is that it also has high requirements for configuration personnel, and the configuration is not flexible. If too many entries need to be inserted between two table entries, the number will not be enough.

Embodiment Construction

[0014] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the present invention implementation, but not all implementations.

[0015] The present invention provides a method for inserting and sorting ACL entries, which does not require the configuration personnel to plan the order in advance, but automatically sorts according to the parameter range of each entry itself. When adding an entry in the ACL table, the entry Find a suitable position according to its own parameter range and insert it into the ACL table.

[0016] The method for inserting and sorting ACL table items of the present invention firstly compares the protocol number ranges in each table item, arranges each table item according to the size of ...

Abstract

The invention discloses an ACL (access control list) table insertion sequencing method. The ACL table insertion sorting method comprises the following steps: comparing protocol number range of every table, sequence every table according to size of the protocol number range, and give priority to sequence the table with small protocol number range. If the protocol number of the table is the same, comparing the original IP (internet protocol) address range in the table, and give priority to sequence the table with small original IP address range. The ACL table insertion sorting method can automatically sequence every table; configuration staff needs not to plan the order of every table in ACL in advance; when a new table is added, the ACL table insertion sorting method can automatically sequence according to the protocol number range in the table and the property of the other parameters and then insert to the ACL table.

Description

technical field [0001] The invention relates to a method for inserting and sorting ACL entries of a switch. Background technique [0002] ACL (Access Control List, Access Control List) realizes the function of packet filtering by configuring matching rules and processing operations for packets. When the port of the switch device receives the message, it analyzes the fields of the message according to the ACL rules applied on the current port, and after identifying the specific message, it allows or prohibits the message to pass according to the preset policy. [0003] ACL classifies data packets through a series of matching conditions. The entries in each group of ACL are strictly ordered. The existing methods for sorting the entries in the ACL table include the following two: [0004] The first is that the configuration personnel plan the order of the entries in each group of ACL in advance. This technology has high requirements for the configuration personnel. When adding...
