Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a method for reducing the consumption of ACE entries. Through the scheme of creating a policy group, the problem of matching a large number of ACLs can be realized through the PC management group, thereby saving TCAM to a great extent resources, and can also simplify management operations

Embodiment Construction

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0014] The present invention provides a method for reducing the consumption of ACE entries, which includes a switch group and a PC management group. In the switch group, an ACE is respectively set to be issued to the chip, and a policy group is created through the chip to the PC management group. The authority group is defined between the switch group and the PC management group, and the access authority between the PC management groups is controlled in the switch group access control list to realize the access control authority.

[0015] see figure 1 As shown, for example, the PC management groups PC1, PC2, and PC3 can all access the switch. Previously, three ACEs {ACE1, ACE2, ACE3} were created and sent to the chip. Now, by delineating the permission group, the group and group are a...

Abstract

The invention provides a method of reducing ACE entry consumption. A switch group and a PC management group are provided. ACE in the switch group are respectively issued to a chip, and the chip is used to create a strategy group to the PC management group. An authority group is arranged between the switch group and the PC management group, and the access authority of the PC management group is controlled in the access control list of the switch group, and then an authority of access control is realized. By adopting the technical scheme of creating the strategy group, the PC management group is used to solve a problem of requirement on matching of a lot of ACL, and therefore TCAM resources are saved to a great extent, and management operation is simplified.

Description

technical field [0001] The invention relates to the technical field of network processors, in particular to a method for reducing consumption of ACE entries. Background technique [0002] The traditional ACL (Access Control List, hereinafter referred to as ACL, translated into Chinese as the access control list, is the command list of the router and switch interface, used to control the data packets entering and leaving the port) technology, which is used to realize the flow identification function, network equipment In order to filter the message, it is necessary to match a series of matching conditions to classify the message. These conditions can be SrcMAC (source mac Address source MAC address), DestMAC (dest mac Address destination MAC address), SrcIP (source ip Address source IP address), DestIP (dest ip Address destination IP address), SrcPort (layer 4source port 4-layer protocol source port), DestPort (layer 4source port 4-layer protocol destination port) and other i...
