How to handle the problem that traffic cannot be transmitted when the NAT or QoS configuration is modified on the physical interface after the dial-up is successful

1

When the dialer_bundle-member command is run in the resource-shared DCC method to set the Dialer bundle that a physical interface belongs to or the dialer circular-group command is run in the circular DCC method to set the dial-up circulation group, traffic cannot be transmitted when the NAT or QoS configuration is modified on the physical interface after the dial-up is successful. In this case, the dial-up connection must be disconnected first and established again to transmit traffic normally. In addition, users must not modify the NAT or QoS configuration on the physical interface after the dial-up is successful.

Why traffic forwarding fails if the NAT or QoS configuration on a physical interface is modified after dialup succeeds
This problem occurs in the following situations: -In RS-DCC, the dialer_bundle-member command is used to specify a dialer bundle for the physical interface. -In C-DCC, the dialer circular-group command is used to specify a dialer circular group for the physical interface. To resume traffic forwarding, terminate the dialup connection and redial to establish a link. After dialup succeeds, do not modify the NAT or QoS configuration on the physical interface.

A traffic policy contains multiple pairs of traffic classifiers and behaviors. How to handle the problem if the GTS CIR command is executed in these pairs and the CIR configured is greater than the CIR configured on the interfaces
If a traffic policy includes multiple pairs of traffic classifiers and behaviors and the GTS CIR command is configured in these pairs. If the CIR of these pairs is greater than that configured on the interface, rate limiting will be configured for the pairs and interfaces.

Handling of the problem that the state of optical interfaces of an AR router is not Up
The handling roadmap of the problem that the state of optical interfaces of an AR router is not Up is as follows: 1. The negotiation methods, rates, and duplex modes of both ends must be the same. 2. Check whether the optical fiber and optical module are matched and used correctly. - Multimode optical fibers can be used with single-mode optical modules in short distance scenarios. - Single-mode optical fibers can be used only with single-mode optical modules. - Check whether the optical interface and optical module are incorrectly matched. For example, a 100M optical interface is connected to a 1000M optical module. - Check whether the optical modules are authorized by Huawei. - Generally, single-mode optical fibers are yellow and multimode optical fibers are orange. 3. Run the display transceiver interface interface-type interface-number command to check whether the wavelength of the optical module to be interconnected is in accordance with that of the optical interface and whether the distance is proper. 4. Run the display transceiver interface interface-type interface-number verbose command to check whether the transmit and receive optical power of the optical interface is normal. 5. If the cause of the problem cannot be determined, consider to replace the optical module and optical fiber.
