TX packets dropped ratio too high-cisco-asa

Vendor: cisco

OS: asa

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

Remediation Steps:
Packet drops usually occur when the rate of packets transmitted is higher than the device ability to handle.
|
|1. Run the “show interface” command to review the interface counters and the bitrate. Consider to configure the “load-interval 30” interface sub command to improve the accuracy of the interface measurements. Check for traffic bursts and high traffic utilization.
|2. Use the “show hardware rate-limit” NX-OS command (if supported) to determine if packets are being dropped because of a rate limit.
|3. Execute the “show policy-map interface control-plane” NX-OS command to determine if packets are being dropped because of a QoS policy.
|4. Use the “show hardware internal statistics rates” to determine if packets are being dropped by the hardware.
|5. Run the “show hardware internal statistics pktflow all” NX-OS command to display per ASIC statistics, including packets into and out of the ASIC. This command helps to identify where packet loss is occurring.

How does this work?
This script retrieves the interface statistics by polling ifTable via SNMP.

Why is this important?
Capture the interface Transmit Drop counter. Packet loss may have severe impact to the traffic utilization (retransmission for TCP apps) and to the performance of the applications

Without Indeni how would you find this?
It is possible to poll this data through SNMP.

    network-interface-mtu:
        why: |
            The Maximum Transmission Unit (MTU) is the maximum frame size that can be sent between two hosts without fragmentation.

    network-interface-speed:
        why: |
            If the interface speed is set to a low value, this could mean auto-negotiation is not working correctly and the interface does not utilize the full bandwidth available.
