Wrong Link State Displayed for Node¶
Symptom¶
The link status showing in the Web Console is incorrect.
Cause¶
- The Network sensor routinely confirms nodes link status. If many nodes are being managed by a sensor, there may be a delay time before the nodes link state is updated.
- This process can be impacted if the if there is a breakdown in communication between the Node and the Network Sensor, or the Policy Server and the Network Sensor.
Resolution¶
Check Communication from the Sensor to the Node¶
- Follow the below steps, as shown in the code box.
- Log in to the Policy Server console directly or by SSH.
- Enter Configuration mode.
- Enter shell mode.
- Use the
arping -Icommand to initiate a mac address request for that nodes IP, sent from the defined interface. this will serve to test communications from the Sensor to the Node.- Check for errors appear in the console. Document and share with Genians engineers.
genian> en
genian# @shell
Genians$ arping -I [interface number] [IP Address]
Example Syntax: arping -I eth0.10 192.168.10.10
Gather System Logs¶
- There may be a problem with communications from the Policy Server to the Sensor.
- Use the Syscollect function on the Policy Server to send info to Genians engineers.
