[0012] 2. For different interfaces, the behavior processing flow of interfaces with similar functions is inconsistent
[0013] 3. It is not conducive to the expansion of the interface, which increases the difficulty of controlling the interface behavior
For example, if it is required to bind DOT1X (interface-specific attribute characteristics; setting these attributes may have some restrictions on other attributes, such as not being able to set IP addresses, etc.

Embodiment Construction

[0029] The present invention corresponds the behavior (Action) of the interface with the interface capability (Ability). Interface capability refers to the possibility of an interface to execute a certain behavior item of the interface, and there is a one-to-one correspondence between capability and behavior. Capability has only two values: YES and NO, indicating whether the interface can execute a certain behavior item. Each behavior of each interface is associated with a set of capability (behavior item) flags. The value of this set of capability flags depends on the characteristics of the interface. For example, the Ethernet interface is in the Layer 3 state when it is created, so its "join VLAN" capability is NO. When disabling a specific capability of an interface, the reason code for disabling must be specified at the same time. An ability can be disabled multiple times, each time for a different reason. When the reason for the prohibition item does not exist, the ca...

Abstract

The invention discloses a checking method for network interface behavior in multiple network interface environment. It includes: 1) creates memory area of network interface behavior information in data base, the network interface access pointer points to the first address of the memory; the network interface behavior information includes behavior items and the sign if the behavior items can be enabled, if it can not be enabled, it also includes the reason that the item can not be enabled; 2) when executing network interface behavior, it executes and checks the enable sign, if yes, it enables the behavior item of the network interface; if can not, it provides the reason. The method is simple, and the concept is clear.

Description

technical field [0001] The invention relates to a multi-network interface control method, in particular to a method for checking network interface behavior in a multi-network interface environment. Background technique [0002] In a multi-function switching device, the system needs to manage various types of interfaces. The interface can be a physical interface, such as Ethernet interface, POS interface and ATM interface, etc.; it can also be a logical interface established on the physical interface, such as Trunk interface [802.1ad], VLAN interface [802.1Q], SuperVLAN, loopback interface Wait. Here, the aggregation of multiple VLANs is SuperVLAN, the main purpose is to save IPv4 addresses; for details, please refer to RFC3069. [0003] Each interface has some attributes, such as interface UP / DOWN status, physical address, interface IP address configuration, interface layer 2 and layer 3 attributes (in short, if the main purpose of the interface is layer 2 forwarding, this...
