Abstract
In an example of a method for implementing three-layer communication of a management packet, a controlling bridge creates a first virtual management ethernet (VME) port with a first MAMA address, and allocates a first IP address to the first VME port. A port extender creates a second VME port with a second MAC address, and requests an IP address of the second VME port from the controlling bridge. The controlling bridge allocates a second IP address to the second VME port, and notifies the port extender of the second IP address and the first IP address; acquires the second MAC address of the second VME port to send receive a management packet to from the second VME port through three-layer communication.
Claims21
A method of implementing three-layer communication, applied to a system comprising a controlling bridge and a port extender, wherein the method comprising:
- creating, by the controlling bridge, a first Virtual Management Ethernet (VME) port with a first Media Access Control (MAC) address, and allocating a first Internet Protocol (IP) address belonging to a management virtual private network to the first VME port;
- creating, by the port extender, a second VME port with a second MAC address;
- requesting, by the port extender, an IP address of the second VME port from the controlling bridge;
- allocating, by the controlling bridge, a second IP address belonging to the management virtual private network to the second VME port, and notifying the port extender of the second IP address and the first IP address;
- acquiring, by the controlling bridge, the second MAC address of the second VME port to send a management packet to the second VME port and receive a management packet from the second VME port through three-layer communication;
- and
- acquiring, by the port extender, the first MAC address of the first VME port to send a management packet to the first VME port and receive a management packet from the first VME port through three-layer communication.
A system for implementing three-layer communication, wherein the system comprises a controlling bridge and a port extender, and a cascade port of the controlling bridge is connected with an upstream port of the port extender;
- the controlling bridge creates a first Virtual Management Ethernet (VME) port with a first Media Access Control (MAC) address, and allocates a first Internet Protocol (IP) address belonging to a management virtual private network to the first VME port;
- the port extender creates a second VME port with a second MAC address, and requests an IP address of the second VME port from the controlling bridge;
- the controlling bridge allocates a second IP address belonging to the management virtual private network to the second VME port, and notifies the port extender of the second IP address and the first IP address;
- the controlling bridge acquires the second MAC address of the second VME port to send a management packet to the second VME port and receive a management packet from the second VME port through three-layer communication;
- and
- the port extender acquires the first MAC address of the first VME port to send a management packet to the first VME port and receive a management packet from the first VME port through three-layer communication.
A controlling bridge, comprising:
- a processor;
- and
- a non-transitory machine-readable storage medium storing machine-executable instructions, wherein by executing the machine-executable instructions, the processor is caused to:
- create a first Virtual Management Ethernet (VME) port with a first Media Access Control (MAC) address, and allocate a first Internet Protocol (IP) address belonging to a management virtual private network to the first VME port;
- receive, from a port extender, an address request message used to request the controlling bridge to allocate an IP address to a second VME port of the port extender;
- allocate a second IP address belonging to the management virtual private network to the second VME port;
- send an address response message for notifying the second IP address and the first IP address to the port extender;
- and
- acquire a second MAC address of the second VME port to send a management packet to the second VME port and receive a management packet from the second VME port through three-layer communication.
