How To Fix RT601 - &1 &3 > &2 &3 (15 Min.) Collisions in LAN exceeds threshold

RT601 - Overview

• Message type: E = Error

• Message class: RT - Monitoring infrastructure MSG and alert texts

• Message number: 601

• Message text: &1 &3 > &2 &3 (15 Min.) Collisions in LAN exceeds threshold

What causes this issue?

The threshold value for collisions in the LAN has been exceeded. A
collision occurs when two stations try to transport a package at the
same time in the same channel, which leads to the destruction of both
data packets - they must therefore both be sent again.

• What is the cause and solution for SAP error message RT601 - &1 &3 > &2 &3 (15 Min.) Collisions in LAN exceeds threshold ?

  The SAP error message RT601 indicates that the number of collisions in the Local Area Network (LAN) has exceeded a predefined threshold. This can lead to performance issues and connectivity problems for users accessing SAP systems. Here’s a breakdown of the cause, potential solutions, and related information for this error:
  
  Cause:
  
  Network Congestion: High traffic on the network can lead to increased collisions, especially in environments using older Ethernet technologies (like 10Base-T).
  Faulty Network Hardware: Malfunctioning network devices (like switches, routers, or network interface cards) can cause excessive collisions.
  Improper Network Configuration: Misconfigured network settings, such as duplex mismatches (half-duplex vs. full-duplex), can lead to collisions.
  Cable Issues: Damaged or poor-quality network cables can also contribute to increased collision rates.
  High Number of Devices: A large number of devices on the same network segment can increase the likelihood of collisions.
  
  Solutions:
  
  Network Analysis: Use network monitoring tools to analyze traffic and identify congestion points. Tools like Wireshark can
