DescriptionIndeni tracks the number of packets that had issues and alerts if the ratio is too high.
Remediation StepsPacket drops usually occur when the rate of packets received is higher than the device's ability to handle.1. Run the "show interface extensive" command to review the interface statistics.
2. Check for packet drops and input/output traffic rate.
3. Run the "show class-of-service interface x/x/x detail" to determine any QoS policy applied to interface which may cause packet drops.
4. If the interface is saturated, the number of packets dropped by the is indicated by the input queue of the I/O Manager ASIC. This number increments once for every packet that is dropped by the ASIC's RED mechanism.
5. Review the following article on Juniper tech support site: Ethernet Switching and Layer 2 Transparent Mode Feature Guide for Security Devices
6. If the problem persists, contact the Juniper Networks Technical Assistance Center (JTAC)
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 Received Errors counter. Packet loss may impact traffic performance.
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.
