Network port(s) running in half duplex-f5-all

Vendor: f5

OS: all

Description:
Indeni will alert one or more network ports is running in half duplex.

Remediation Steps:
Many times ports are in half duplex due to an autonegotation error or a misconfiguration.

How does this work?
This alert logs into the F5 unit through the iControl REST API and retrieves the status of all network interfaces. In that output, it looks for the actual runtime duplex of each interface.

Why is this important?
Generally, these days network interfaces are set at full duplex. Sometimes, due to a configuration or device issue, an interface can be set to half duplex. As that is usually not the intended behavior, it is important to track the duplex setting of all network interfaces.

Without Indeni how would you find this?
An administrator could login to the web interface of the device and go to Network -> Interfaces and click on each interface in the list to see the duplex of each interface. This information is also available by logging into the device through SSH, entering TMSH and executing the command “show net interface all-properties” and looking at the column “Media”. A value of “FD” means “Full Duplex”, while a value of “HD” means “Half Duplex”. Example: 1000T-FD means “Speed: 1000 Mbit, Duplex: Full, Media Type: Copper Twister Pair”.

    network-interface-state:
        why: |
            Interfaces in the "down" state could result in downtime or reduced redundancy.
        how: |
            The state of the interface is retrieved via the F5 iControl REST API.
        without-indeni: |
            An administrator could login to the web interface of the device and go to Network -> Interfaces to see the status of each interface. This information is also available by logging into the device through SSH, entering TMSH and executing the command "show net interface all-properties".

        can-with-syslog: false
    network-interface-admin-state:
        why: |
            An administrator might set a network interface to be disabled for troubleshooting, but. Should he he forget about doing this network trunks might be running at reduced capacity.
        how: |
            This alert uses the F5 iControl REST API to retrieve the status of all physical network interfaces. In that output, it looks for interfaces that are set to be up, but are actually down.
        without-indeni: |
            An administrator could login to the web interface of the device and go to Network -> Interfaces to see the admin status of each interface.

    network-interface-mac:
        why: |
            To be able to search for MAC addresses in indeni, this data needs to be stored.
        how: |
            This alert uses the F5 iControl REST API to retrieve the MAC addresses of all physical network interfaces.

        can-with-syslog: false
    network-interface-mtu:
        why: |
            The MTU sometimes needs to be adjusted. Storing this gives an administrator an easy way to view the MTU from a large number of devices, as well as identifying incorrectly set MTU.
        how: |
            This alert uses the F5 iControl REST API to retrieve the MTU from all physical interfaces.
        without-indeni: |
            An administrator could log into the device through SSH, entering TMSH and executing the command "show net interface all-properties" to see the MTU for each interface.

    network-interface-rx-packets:
        why: |
            Tracking the number of packets flowing through each network interface is important to identify potential issues, spikes in traffic, etc.
        how: |
            This alert logs into the F5 unit through the F5 iControl REST API and retrieves the metrics from all network interfaces. In that output, it looks for the number of packets received through the interface.
        without-indeni: |
            An administrator could login to the web interface of the device and go to Network -> Interfaces -> Statistics to see the statistics of each interface.

    network-interface-rx-dropped:
        why: |
            If incoming packets are being dropped on a network interface, it is important to be aware of it. This may be due to a high load on the unit, or another capacity issue.

    network-interface-speed:
        why: |
            Generally, these days network interfaces are set at 1Gbps or more. Sometimes, due to a configuration or device issue, an interface can be set below that (to 100mbps or even 10mbps). As that is usually _not_ the intended behavior, it is important to track the speed of all network interfaces.

            This alert logs into the F5 unit through the iControl REST API and retrieves the status of all network interfaces. In that output, it looks for the actual runtime speed of each interface.
        without-indeni: |
            An administrator could login to the web interface of the device and go to Network -> Interfaces to see the speed of each interface by looking at the column "Media Speed". This information is also available by logging into the device through SSH, entering TMSH and executing the command "show net interface all-properties" and looking at the column "Media". The numbers are the value of the speed in "MegaBits". Example: 1000T-FD means "1000 Mbit".

            Generally, these days network interfaces are set at full duplex. Sometimes, due to a configuration or device issue, an interface can be set to half duplex. As that is usually _not_ the intended behavior, it is important to track the duplex setting of all network interfaces.

    network-interface-type:
        why: |
            The type of interface can be useful for administrators.
