Understanding and Resolving the Mx2020 MPC11E Error: aft-proxy Retires Expired Gencfg Request (0x39, 0x7, 0x3)

The Mx2020 MPC11E is a high-performance router designed for large-scale networks, providing advanced features and functionalities to support the ever-growing demands of modern networking. However, like any complex system, it is not immune to errors and issues. One such error that has been reported by users is the “aft-proxy Retires Expired Gencfg Request (0x39, 0x7, 0x3)” error. In this article, we will delve into the details of this error, its causes, and possible solutions.

What is the aft-proxy Retires Expired Gencfg Request Error?

The aft-proxy Retires Expired Gencfg Request error is a specific type of error that occurs on the Mx2020 MPC11E router. It is characterized by the error code (0x39, 0x7, 0x3), which indicates that the aft-proxy process has retired an expired Gencfg request. But what does this mean exactly?

To understand this error, we need to break down the components involved:

• aft-proxy: The aft-proxy is a process that runs on the Mx2020 MPC11E router, responsible for managing and forwarding configuration requests to the router’s configuration database.
• Gencfg Request: A Gencfg request is a type of configuration request that is sent to the router’s configuration database to retrieve or update configuration information.
• Expired Gencfg Request: An expired Gencfg request is a request that has timed out or is no longer valid.

When the aft-proxy process encounters an expired Gencfg request, it retires the request, which means it removes it from the queue and prevents it from being processed further. This is a normal behavior, as expired requests can cause issues and inconsistencies in the router’s configuration.

Causes of the aft-proxy Retires Expired Gencfg Request Error

So, what causes the aft-proxy Retires Expired Gencfg Request error? There are several possible reasons:

• Configuration Issues: The most common cause of this error is a configuration issue, such as a misconfigured router or a mismatch between the router’s configuration and the configuration database.
• Network Connectivity Issues: Network connectivity issues, such as packet loss or high latency, can cause Gencfg requests to time out or become expired.
• Router Overload: If the router is experiencing high CPU utilization or memory issues, it may not be able to process Gencfg requests in a timely manner, leading to expired requests.
• Software Bugs: In some cases, software bugs or defects in the router’s operating system or configuration software can cause the aft-proxy Retires Expired Gencfg Request error.

Troubleshooting the aft-proxy Retires Expired Gencfg Request Error

Troubleshooting the aft-proxy Retires Expired Gencfg Request error requires a systematic approach. Here are some steps you can take:

• Check the Router’s Configuration: Verify that the router’s configuration is correct and consistent with the configuration database.
• Verify Network Connectivity: Check for any network connectivity issues, such as packet loss or high latency, and resolve them if necessary.
• Monitor Router Performance: Monitor the router’s CPU utilization and memory usage to ensure it is not overloaded.
• Check for Software Updates: Check for any software updates or patches that may resolve the issue.

Resolving the aft-proxy Retires Expired Gencfg Request Error

Once you have identified the cause of the aft-proxy Retires Expired Gencfg Request error, you can take steps to resolve it. Here are some possible solutions:

• Correct Configuration Issues: If the error is caused by a configuration issue, correct the configuration and restart the router.
• Improve Network Connectivity: If the error is caused by network connectivity issues, take steps to improve network connectivity, such as upgrading network infrastructure or adjusting network settings.
• Optimize Router Performance: If the error is caused by router overload, take steps to optimize router performance, such as upgrading the router’s hardware or adjusting its configuration.
• Apply Software Patches: If the error is caused by a software bug, apply the necessary software patches or updates.
