A vlanTrunkPortDynamicStatusChange

health_canada123 · ‎11-22-2011

Hi there,

On our network we are receiving many of these informational traps. We have many devices on our networks however the following error presents its self regularly or occasionally on only a small percentage of our devices. Couldnt find a clear explanation of what it means and how to fix it properly.

Our trunks are all configured with switchport mode trunk and nonenegotiate.

1. Error on our network monitoring system.

A vlanTrunkPortDynamicStatusChange notification is generated by a device when the value of vlanTrunkPortDynamicStatus object has been changed.

Thanks

R
