RX packets overrun for Juniper




Indeni tracks the number of packets that had issues and alerts if the ratio is too high.

Remediation Steps

Packet overruns usually occur when there are too many packets being inserted into the port's memory buffer, faster than the rate at which the kernel is able to process them.The issue can not be resolved on the device that reports overruns. The rate that frames are coming should be controlled at the remote end of the connection.
1. Run the "show interface extensive" command to review the interface overrun counters. 

2. If the number of overruns is high, consider upgrading the hardware.
3. Review the following article on Juniper tech support site: Operational Commands

How does this work?

This script logs into the Juniper JUNOS-based device using SSH and retrieves the output of the "show interfaces extensive" command. The output includes all the interface related information and statistics.

Why is this important?

Capture the interface Receive Overrun errors counter.

Without Indeni how would you find this?

There are many solutions out there for tracking traffic flow on network interfaces and alerting when critical indicators are reached.
