Network interface duplex does not match across cluster members for F5

Vendor

F5

Description

Indeni will identify when two devices are part of a cluster and alert if their network interface duplex are different.

Remediation Steps

Ensure the network interface duplex setting matches across devices in a cluster.

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.

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".
