Network port(s) running in half duplex-juniper-junos
Vendor: juniper
OS: junos
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 script logs into the Juniper JUNOS-based device using SSH and retrieves the output of the “show interfaces extensive” command. The output includes all the interface related information and statistics.
Why is this important?
Capture the interface duplex in human readable format such as full or half. In modern network environments it is very uncommon to see half-duplex interfaces, and that should be an indication for a potential exception.
Without Indeni how would you find this?
It is possible to poll this data through SNMP. If a duplex mismatch is detected on a port syslog messages will be generated.
