Embodiment 1

[0087] figure 1 It is the flow chart of Ethernet IP address management provided by the present invention, such as figure 1 As shown, the management method includes the following steps:

[0088] Before step 101, it also includes the system initialization phase. The switches in the LAN are configured with VLANs, the root switch selected by the spanning tree protocol is run, or the administrator designates a switch as the root switch, and a password is configured on the root switch and the non-root switch. Switches and non-root switches use PKCS#5v2.1 password-based message authentication scheme PBMAC1 for message authentication to prevent hackers and virus attacks. The administrator configures the DHCP server information on the root switch, including:

[0089] 1) DHCP Pool Name: address pool name (dhcp pool-name);

[0090] 2) DHCP Mask: Subnet mask;

[0091] 3) DHCP IP: address segment;

[0092] 4) DHCP Gateway: Gateway IP and MAC;

[0093] 5) DHCP Exclude ip: reserved address;

[0094] 6...

Embodiment 2

[0155] The present invention also provides a switch IP address management method in an Ethernet environment, including:

[0156] Configure the virtual local area network (VLAN) of the switches in the local area network, run the spanning tree protocol to determine the root switch, and determine that the remaining switches are non-root switches.

[0157] The password-based message authentication scheme (PBMAC1) performs message authentication on the root switch and the non-root switch, and configures dynamic host configuration protocol DHCP server information on the root switch; the DHCP server information includes the address pool name , Subnet mask, address segment, gateway IP, gateway media access control address MAC address, reserved IP address, domain name server and VLAN number for DHCP service.

[0158] Obtain the device query request of the root switch.

[0159] According to the password-based message authentication scheme (PBMAC1), it is judged whether the device query request ...

Embodiment 3

[0188] The present invention also provides a switch IP address management system in an Ethernet environment, including:

[0189] The root switch determining module is used to configure the virtual local area network (VLAN) of the switches in the local area network, run the spanning tree protocol to determine the root switch, and determine that the remaining switches are non-root switches.

[0190] The message authentication module is used for a password-based message authentication scheme (PBMAC1) to perform message authentication on the root switch and the non-root switch, and configure dynamic host configuration protocol DHCP server information on the root switch; the DHCP The server information includes the address pool name, subnet mask, address segment, gateway IP, gateway media access control address MAC address, reserved IP address, domain name server, and VLAN number of the DHCP service.

[0191] The device query request obtaining module is used to obtain the device query req...

Abstract

The invention discloses a switch IP address management method and system in the Ethernet environment. The management method includes, based on the spanning tree protocol, utilizing the root switch to realize the DHCP service management of the whole network, assigning IP addresses according to the number of ports of the switch, each switch can provide DHCP services, and serving the connections connected to the switch according to the IP address assigned by the root switch. Terminal; when the switch receives the ARP request sent by the terminal for the MAC address corresponding to the i-th IP, the switch can know the MAC of the switch j where the legal i-th IP address is located according to the database switch, and use the MAC address of the switch j as the i-th IP The corresponding MAC address. Adopting the management method and system provided by the present invention can realize the automatic management of IP addresses in the local area network, and there is no need to transmit the ARP protocol and the DHCP protocol between the switches, which reduces most of the broadcast traffic in the local area network, fundamentally eliminates broadcast storms, ARP viruses, Improve the utilization rate of LAN network bandwidth and improve network security.

Description

Technical field [0001] The present invention relates to the field of IP address management, in particular to a method and system for switch IP address management in an Ethernet environment. Background technique [0002] With the improvement of informatization and the continuous expansion of network scale, the devices connected to the network continue to increase, and network traffic management is becoming increasingly important. In the Ethernet environment, Address Resolution Protocol (ARP) and Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) are usually essential and important protocols, but these protocols are not designed to prevent malicious attacks. Features. In response to the DHCP protocol, attackers may publish false gateway addresses, Internet Protocol Address (IP) address pools, or even incorrect Domain Name System (DNS) server information. If these illegal DHCP designated DNS servers are compromised Deliberate modification may lead user...
