TX packets experienced collisions-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 collisions usually occur when there is a mismatch in duplex settings on two sides of a cable.

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

Why is this important?
Capture the interface Transmit Packets counter. Knowing the amount of bytes and packets flowing through an interface can help estimate an interface’s performance and utilization.

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.
        how: |
            This script retrieves the interface MTU Setting by polling ifTable via SNMP.

        can-with-snmp: true
        can-with-syslog: false
    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.
        how: |
            This script retrieves the interface speed by polling ifTable via SNMP.

        can-with-syslog: false
    network-interface-mac:
        why: |
            A media access control address (MAC address) is a unique identifier assigned to a network interface.
        how: |
            This script retrieves the interface MAC Address by polling ifTable via SNMP.

            It is possible to poll this data through SNMP.
        can-with-snmp: true
        can-with-syslog: false
    network-interface-admin-state:
        why: |
           If an interface is disabled and it is a member of a Port Channel, then the link might be running at reduced capacity.
        how: |
            This script retrieves the interface administrative state by polling ifTable via SNMP.
        without-indeni: |
            It is possible to poll this data through SNMP.

    network-interface-state:
        why: |
            Interfaces that should be UP and are DOWN can reduce the resiliance of the systems and cause service disruption.
        how: |
            This script retrieves the interface state by polling ifTable via SNMP.

    network-interface-rx-dropped:
        why: |
            Capture the interface Receive Drop counter. Packet loss may have severe impact to the traffic utilization (retransmission for TCP apps) and to the performance of the applications
