Embodiment Construction

[0029] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] It should be noted that VLAN attributes are divided into internal and external IP address allocation methods, which correspond to the built-in DHCP SERVER allocation and external DHCP SERVER allocation modes respectively. Among them, the built-in DHCP SERVER distribution method is to assign IP addresses to clients through the built-in address pool; the external DHCPSERVER distribution method is to forward the client's DHCP request message through the built-in DHCP RELAY, so that other devices that support DHCP SERVER can respond to client address requests , to assign an IP address to it. Therefore, if it is a built-in DHCP server, when the device receives a DHCP request message from a client, it will assign an address to the client in the built-in address pool; if there is no built-in DHCPSERVER in the switch,...

Abstract

The invention discloses a method of automatically establishing virtual local area network (VLAN) address tank, including: A. obtaining VLAN ID by command line or network management agent module interface function; B. using the VLAN ID to call the corresponding relationship between the VLAN ID and three-layer interface Internet protocol (IP) address as well as subnet mask (MASK) so as to obtain IP and MASK, and then judging if it succeeds in obtaining them: if it does, execute the step C and otherwise fail in establishing address tank; C. setting the VLAN property into an internal allocating mode and according to the obtained IP address and MASK, establishing the address tank. It omits the fussy course that the user manually configures an address tank and establishes binding, especially effective for larger numbers of VLANs.

Description

technical field [0001] The invention relates to an IP address distribution technology, in particular to a method for automatically creating a virtual local area network (VLAN) address pool. Background technique [0002] Dynamic Host Configuration Protocol (DHCP) is a protocol that enables clients to obtain configuration information on a TCP / IP network. This protocol is based on the BOOTP protocol, and on the basis of the BOOTP protocol, functions such as automatic allocation of available network addresses are added. , Completely solve the problems such as difficult management and easy conflicts caused by statically assigned IP addresses. [0003] At present, using a DHCP server (SERVER) to assign IP addresses to clients is a necessary means. At the same time, in order to save the operator's investment, a built-in DHCP SERVER network switch has appeared, which can save the investment of a DHCP SERVER server. [0004] When the network switch adopts the built-in DHCP SERVER, ...
