Two Routers Are Connected Through CPOS Interfaces, but the Link Layer Status of the Logical Channel Keeps Alternating Between Up and Down

Two Routers Are Connected Through CPOS Interfaces, but the Link Layer Status of the Logical Channel Keeps Alternating Between Up and Down

Fault Description

Two routers are connected through CPOS interfaces, and CPOS interfaces are bundled into a large number of logical channels. The link layer status of the logical channel keeps alternating between Up and Down.

Fault Cause

Too many logical channels affect processing capability of the system.

Troubleshooting Procedure

This problem can be solved using the following two methods:

  • Method 1: Run the ppp mp max-bind max-bind-number command on the VT or MP-Group interface to change the maximum number of bundled links of an MP. This reduces idle logical links bundled on the CPOS interface until the protocol status of the logical channel keeps stable.

  • Method 2: Configure CPU attack defense. PPP of the logical channel is used as an example.

    1. Run the packet-type ppp rate-limit rate-value command in the attack defense policy view to increase the rate limit for sending packets to the CPU.
    2. Apply the attack defense policy in the system view.
    3. Repeat the preceding operations until the link layer status of the logical link is in a stable state.
