Print Server - Firmware Errors

Lexmark printers are not exactly renowned for their reliability. Are they generating error logs?

Sir, echoing Brian, is it more than one printer? How often does it occur?

If it is more than one printer with a firmware issue after you created a subnet, it may be related to Unpnp or some other network advertising/discovery that the printer is attempting now that it 'sees' another network that wasn't there before.

Is there static or dynamic routing by the router that is going on now that wasn't present before? Of course it shouldn't require a reboot in any event.

1. update the printer firmware if possible

2. try taking the subnet down temporarily if possible, and if the problem manifests quickly enough to confirm a correlation.

3. if the printers don't need to see beyond their local subnet you can try to leave the default gateway setting blank on the printer to see if that has an effect.

4. Double check static/dynamic routing for sanity

5. Make sure there is only one DHCP server running per ethernet segment

Hi, Mr. Video. I'm afraid I'm having trouble visualizing your network topology. Let me back-up and ask a coupl basIc questions.

1. You say there is a "main" network with one router on, does the router route only between your LAN and the Internet, or is it only routing traffic between different IP subnets?

2. What makes what you call your "subnetwork" a subnetwork, is it a true IP subnetwork with a different class c address or a netmask, or do you just mean a layer 2 ethernet bridge/switcb or two? Give an example of a server ip and camera ip and printer ip.

3. You say that the cameras have a different default gateway than the printers. But if you only have one router and you are using that to get to the internet then you would only have one ip to use as your default gateway, not two. Give example of the two different gateway values.

The reason to leave the gateway blank if possible was to stop the printer from being able to talk to another subnet.

Thx

May be his server has 2 network cards

One for cameras and One for Corporate Lan

Solution:

1. Get a time machine

2. Go back to 1998 and call Axis tech support.

Hi, Mr. Video.

1. You say there is a "main" network with one router on, does the router route only between your LAN and the Internet, or is it only routing traffic between different IP subnets?

Only Lan and Internet. There is also a Firebox on that aspect of the LAN

2. What makes what you call your "subnetwork" a subnetwork, is it a true IP subnetwork with a different class c address or a netmask, or do you just mean a layer 2 ethernet bridge/switcb or two? Give an example of a server ip and camera ip and printer ip.

The main Lan is 10.11.X.X net mask 255.255.255.0

The camera network is 192.168.x.x

Both servers have a dual NIC's and the both mhave addressing 10.11.x.x and 192.168.x.x on each of the NIC's

3. You say that the cameras have a different default gateway than the printers. But if you only have one router and you are using that to get to the internet then you would only have one ip to use as your default gateway, not two. Give example of the two different gateway values.

The "default gateway" ion the cameras and server NIC is just for consistency, there is a Layer 2 swicth on the building where some of the cameras are hosted.

The reason to leave the gateway blank if possible was to stop the printer from being able to talk to another subnet.

- wouldn't that be prevented by having a default gateway as opposed to not? Also would DNS settings on the cameras have any issues?
