TX packets overrun for Juniper

Vendor

Juniper

Description

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
