Niagara Ultra Slow to Update Values. Need help with pcap capture across VLANs
I have a site that is running extremely slow. I’m not the controls contractor. I’m the general contractor. I believe we have an issue that current controls contractor’s team is not equipped to resolve.
I’m concerned because the current server is the base for 2 additional buildings. With things being slow now, it will only get worse.
This is a Niagara system. Standalone OT network. 3 floors. Each floor is a separate VLAN. One other small building is yet another VLAN. Subnet is 255.255.255.0. Each floor is a string of xxx.xxx.1.xxx for first and xxx.xxx.2.xxx for the second and so on. Mostly BACnet IP. Some MS/TP, even less Modbus.
I understand building automation controls relatively well. I understand networking less. This contractor is responsible for the network design and implementation.
I’m confident there is a problem here that needs to be resolved. I figure it’s one of 4 things:
Server at capacity. Doubtful given server specs. But, improper configuration of Niagara could create this issue as well.
Network design/implementation problem.
Niagara setup/implementation
All of the above.
What I’m trying to do with this post is start to narrow down so I can have them resolve.
Where I wanted to start was run an Optigo report of the BACnet traffic. To do this, I need a PCAP capture of traffic. The controls contractor is only able to get me one VLAN at a time. I need all VLANs at once. Then run a global who is to make everything talk during the capture.
Can anyone help? I know it’s broad. I’ll try to answer any questions I can.
