Method and device for supporting login of multi-serial port terminal

Abstract

The invention discloses a method for supporting login of a multi-serial port terminal. The method comprises the following steps of: when the serial port terminal initiates a login request, sending the login request to a main control board of a machine frame of a main SC; determining whether to allow the login of the serial port terminal which initiates the login request through the main control board of the machine frame of the main SC, and returning the login result to the serial port terminal. The invention also discloses a device for supporting the login of the multi-serial port terminal at the same time. The method and the device of the invention enable the serial port terminal of the main control board on any machine frame to realize login request and perform operation, have the same operation effect as the serial port terminal of the main control board of the machine frame of the main SC, and can enter the OAM interface to perform equipment configuration management operation so as to avoid equipment reversal of the machine frames of the main SC and the backup SC, effective prevent abrading the equipment and facilitate equipment maintenance.

Description

technical field [0001] The invention relates to terminal login technology, in particular to a method and device for supporting terminal login with multiple serial ports. Background technique [0002] With the rapid development of the network, the network has put forward higher and higher requirements for the interface capacity and switching capacity of the chassis connection equipment. demand. At present, the cluster technology is usually used to interconnect the original single-chassis connection devices to form a new multi-chassis connection device, so as to expand the switching capacity and interface capacity to meet user needs. [0003] As a widely used connection device in network systems, routers not only require high reliability data transmission functions, but also require scalability. The cluster technology is introduced into the field of routers, and the purpose is to use two or more ordinary routers. The cluster technology is connected to form a router cluster d...

AI Technical Summary

Problems solved by technology

[0005] In a traditional router cluster device, only the serial terminal on the main control board of the chassis where the main SC is located is allowed to log in and perform operations, such as Operation Administration Maintenance (OAM) operations. The serial port terminal of the main control board does not allow login and operation, which lacks flexibility

In addition, if the serial port terminal on the main control board of the chassis where the active SC is located is damaged or unavailable due to other reasons, the active / standby switchover must be performed on the shelf where the active SC is located and the shelf where the standby SC is located. A new serial port terminal that allows login is available, but this active / standby switching operation will cause equipment wear and tear, and is not conducive to equipment maintenance
