Hi to all,
I am currently trying to reach a printer on another network using a Layer 3 switch (Cisco 3750)
Here is a simplified diagram :
WIFI ROUTER ------------------- CISCO 3750
(10.1.100.1) VLAN 1 (10.1.100.4) -------------------- Business network (10.1.100.xx)
VLAN 20 (192.168.2.92) --------------- Second network (192.168.2.xxx)
I am trying to reach a printer at address 192.168.2.50
From the 3750 CLI, I can successfully ping 192.168.2.92 and 192.168.2.50
After setting up a static route in the Wifi router (192.168.2.0 255.255.255.0 10.1.100.4), I can ping 192.168.2.92
The router is a Asus RT-N66U with default gateway at 10.1.100.1
I still cannot find a way to reach 192.168.2.50
Could someone help me ?
Thanks & regards,

Hi,
Can you check the default gateway on your printer ?
----
I can successfully ping 192.168.2.92 and 192.168.2.50
---
Even if the default gateway is not configured on the printer, this communication will be possible. Because both ends are in the same network: 192.168.2.0.
But in the other case from the printer's end the destination will be:10.1.100.0/24. If the default gateway is not configured on the printer, it would probably don't know where to send the packets ?
If possible, can you please also post a traceroute from the device you are trying to speak to printer?
Rate if it is helpful.

You are correct, When pinging with a source address of 10.1.100.4 I did not get a reply.
Since I am not the manager of the printer and cannot change the gateway to 192.168.2.92, I asked to add a static route in the other network router :
10.1.100.0 255.255.255.0 192.168.2.92
At this time I was able to ping but cannot print at all.
Then I asked for port 9100 to be un locked.
Now I can start a print job but it stops halfway, gives an error and the job restart, stop halfway, restart ... on and on
Any ideas ?

Thanks for the feedback. Please rate my previous post.
And regarding the print job, are you seeing any packet loss while pinging the printer from your device ?
If possible check if this is happening if you're printing from the local device instead from the remote device.

You are correct .. when pinging in windows from a 10.1.100.xx client with command :
ping 192.168.2.50 -t
I don't get a ping response about 1 time in 25 requests
Printing from the local device works fine.
What could be the cause of this ?
01-08-2014 04:11 AM
That 1time "Request failed" will be probably for an ARP. So that is not a problem.
Usually in my LAN whenever i get these type of issues, it would be probably related to only one PC. Printing from other PC would be fine most of the time.
I used to shutdown the PC & Printer for few mins & Power up then the issue used to solved.

I tried with another PC on the network already and had the same problem

Correlate the printing preferences and printer settings on both the local device and the remote device.
Give a try.

Chandu

I used the same computer on both network so configuration is not a problem
01-08-2014 11:09 AM
EDIT : Thinking about it, I asked the IT guy to make the route but did not specify a metric value. Could that be the problem if the metric is only set to 1 ? Also, on the tracert that does not work, I cannot ping 10.1.100.10 neither.
Another weird thing :
