We have a strange problem sometimes.
After network cable was switched off from switch port Zabbix says that this port is in half-duplex mode. At the same time this port is inactive and no traffic exist.
Screenshots are attached

Hello Vladimir,

I believe you are using SNMP. So in such case Zabbix will store the output of the snmpget request. Which actually means you need to:

1. Check the value by issuing snmpget from server for this particular OID/MIB when the problem occurs;
2. Check the database for stored value;

The ZBX is a bug tracker not a support page. For community support visit : https://www.zabbix.com/forum/index.php or ask for help directly from Zabbix Professionals: https://www.zabbix.com/services

P.S. - When you are asking for help - try to provide as much information as possible - Zabbix version, Item type, Host type(Manufacturer/Model) and any other useful info.

Regards,
Aleksejs!

Hello Aleksejs,
I do use SNMP and I don't understand why this issue relates to support page. I registered the similar request https://support.zabbix.com/browse/ZBX-12688 and it was considered as an Error. To my mind this issue is the same. My port is down but how is it connected with half-duplex?

And one more comment.

I noticed Zabbix server version, I noticed host type with manufacturer. I added screenshot with Item type.

There is a known issue with HP switches they return half duplex and 10mb when interface goes down. Currently I suggest to disable this trigger in HP switch template. We might try to fix it in future template version

Comment by Vitaly Zhuravlev [ 2017 Oct 06 ]

Vladimir, there are two templates for HP of different flavors. Did you mean Template_Net_HP_Enterprise_Switch_SNMPv2?

Comment by Vladimir [ 2017 Oct 06 ]

Yes. It's Template_Net_HP_Enterprise_Switch_SNMPv2.
One more clarification. These triggers are created by another template Template Module EtherLike-MIB SNMPv2. And if I disable it there I disable these triggers for all my D-Link switches also.

Comment by Vitaly Zhuravlev [ 2017 Oct 06 ]

I think you can then just detach this Template Module EtherLike-MIB SNMPv2 from Template_Net_HP_Enterprise_Switch_SNMPv2, since it only contains this halfduplex item and trigger.

Comment by Vladimir [ 2017 Oct 06 ]

Yes, it's the solution.
Thanks a lot.
