Network port(s) running in half duplex-paloaltonetworks-panos

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 Palo Alto Networks firewall through 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?
The duplex setting of network interfaces can be manually reviewed through the CLI.
