Description
Technical Field
The invention relates to a network communication technology, in particular to a system and a method for automatically adjusting an Ethernet port negotiation mode.
Background
The conventional ethernet port negotiation technique is introduced as follows:
the port auto-negotiation mode is that the port automatically adjusts the speed of the device to the highest working level according to the connection speed and the duplex mode of the device at the other end, namely the fastest speed and the duplex mode which can be possessed by the two ends of the line. 1. The two-end operation mode of the ethernet port (10M half duplex, 10M full duplex, 100M half duplex, 100M full duplex, auto-negotiation) must be set to be consistent. 3. If one end works in a full-duplex mode and the other end works in a half-duplex mode (including auto-negotiated half-duplex mode, the same treatment is also performed), Ping has no problem, no problem exists when the flow is small, and when the flow reaches more than about 15%, collision and packet error occur, which finally affects the working performance! If one end is in fixed mode (no matter 10M, 100M) and the other end is in auto-negotiation mode, even if the negotiation can be successful, the auto-negotiation end can only work in half-duplex mode.
Based on the above scenario, it can be seen that the negotiation of the ethernet port needs to follow the principle that the negotiation modes of the two end devices to be docked have to be consistent, and in practical applications, the default negotiation modes of the ports of each manufacturer are not necessarily consistent, which sometimes results in a situation that the two ends cannot be docked due to one-end forcing and one-end self-adaptation. The invention discloses a method and a system for automatically adjusting an Ethernet port negotiation mode.
Disclosure of Invention
The method and the system for automatically adjusting the negotiation mode of the Ethernet port can solve the problem that the interface can not be UP due to incompatibility in the butt joint of new and old equipment realized by different manufacturers at different time in practical application.
The scheme of the invention is as follows: a system for automatically adjusting an ethernet port negotiation mode, comprising:
the initialization port negotiation mode module is used for setting a port default negotiation mode;
the port negotiation state judging module is used for judging whether the current port negotiation is successful or not and whether the port is UP or not;
the delay module is used for delaying the next operation and preventing the equipment from being impacted too frequently;
and a module for setting the port negotiation mode, which is used for switching the port negotiation mode when the negotiation fails.
A method for adjusting a system for automatically adjusting an Ethernet port negotiation mode includes the following steps:
step 1: initializing a local terminal negotiation mode into a self-adaptive mode;
step 2: judging whether the current interface is UP;
and step 3: if so, ending the processing, otherwise, delaying and continuing the next processing;
and 4, step 4: setting a local terminal negotiation mode as a forced 1G full duplex negotiation mode;
and 5: judging whether the current interface is UP;
step 6: if so, ending the processing, otherwise, delaying and continuing the next processing;
and 7: setting a local terminal negotiation mode as a forced 100M full duplex negotiation mode;
and 8: and judging whether the current interface is UP.
And step 9: if so, ending the processing, otherwise delaying and continuing the next processing.
Step 10: and setting the local terminal negotiation mode as a forced 10M full duplex negotiation mode.
Step 11: and judging whether the current interface is UP.
Step 12: if yes, ending the processing, otherwise, delaying and continuing the processing of the step 1
The invention can realize successful negotiation when the negotiation modes of the equipment at the two ends are not consistent, greatly improves compatibility and improves the success rate of butt joint.
The invention solves the problem of incompatibility in the process of realizing the butt joint of new and old equipment by different manufacturers at different time in practical application, avoids manual change of a negotiation mode, greatly improves the butt joint compatibility of the equipment and simplifies the time of successful butt joint; the opening efficiency of the client equipment is improved. And manual field treatment is avoided, and the maintenance cost is saved.

initializing port negotiation mode module, port negotiation state judging module, delaying module and setting port negotiation mode module
The initialization port negotiation mode module is used for setting a port default negotiation mode;
the port negotiation state judging module judges whether the current port negotiation is successful or not and whether the port is UP or not;
the delay module delays the next operation to prevent the equipment from being impacted too frequently;
the port negotiation mode setting module is used for switching the port negotiation mode when the negotiation fails;
as shown in fig. 2, in the method and system for automatically adjusting the negotiation mode of the ethernet port according to the present embodiment, the negotiation process includes:
interface negotiation begins;
initializing a local terminal negotiation mode into a self-adaptive mode;
judging whether the local terminal interface is UP, if so, ending the processing flow;
otherwise, setting a delay timer;
after delaying, switching the home terminal negotiation mode into a forced 1G full duplex negotiation mode;
judging whether the port is UP, if so, ending the processing flow;
otherwise, setting a delay timer;
after delaying, switching the home terminal negotiation mode into a forced 100M full duplex negotiation mode;
judging whether the local terminal interface is UP, if so, ending the processing flow;
