A router has several interfaces, each of which corresponds to an attribute.
When the Internet bar router interface fails, it is necessary to solve the problem in time. Before talking about the processing method of router interface fault, the small part first briefly introduces the router CE1 interface. The router CE1 interface is to use 2 m, a E1 as a number of 64k and its combination, which is CE1. The bandwidth of the CE1 transmission line is 2048k.
Suppose that the Internet Café Router A and other manufacturer's device B are connected through the CE1 link, bandwidth of 2M, after the configuration is completed, found that there is a large number of packet overflow alarms on B, on a, when there is no traffic on the CE1 interface, message transmission time delay is normal, when the CE1 interface on the flow, Shiyanda to more than 300 seconds, slow speed.
The following is a specific breakdown analysis
1. Check the transmission link: no abnormal alarms are found on the network management system of the transmission equipment, and the transmission link problem is excluded.
2. Check the port flow: through observation, even in the peak of business, traffic is only more than 500 kbit/s, excluding due to excessive port traffic caused by the slow speed of the problem.
3. Check a interface configuration using the Displaythis command: Find the CE1 interface on a is default to frame mode, while the interface on B is configured as not frame mode.
It should be noted that, by default, working in frame mode, if the interface working mode at both ends of the CE1 link is inconsistent, it may cause a slow or impassability network problem.
The following is the method of the Internet bar router interface fault handling.
1, the execution System-view, enters the system view.
2, execute controllere11/0/0, enter CE1 interface view.
3, the implementation of USINGE1, configuration CE1 interface mode of operation is not in frame mode.
4, perform return returns to the user view, execute command Save, save the changes to the configuration.
The CE1 interfaces for A and B are all working in a non frame mode, and the interface working mode at both ends of the CE1 link must be consistent in order for the business to handle properly. According to the above operation, the Internet Bar router interface fault can be solved.
