There are two different physical locations in the same VLAN, but different subnets. We are trying to install a UPS at one location, and the snmp traps need to be sent to a server in the second location, but in the same VLAN. Gateway is not entered in the SNMP hardware since we were told that...

One more question So, in a managed switchrouter with VLAN/multiple networks, it is difficult to set wrong subnet mask to a device? But how does the switch know what sunet mask is set inside, id subnet mask is totally personal to the device, unknown to external devices? Does it also mean that...

Thank you. So,it is clear that if there is no VLAN, subnets don't make much sense. Please let me know if the following statements are true. 2 and 3 are similar. 1. A device connected to a switch uses its subnet mask only to decide if destination IP is in the net or or outside the router/VLAN...

Thanks for the answer. 1. Even though broadcasts are segmented into neworks, they do appear at the network port of each device, right? Or does the switch intelligently filter out signals into every port, the way router does? Does the switch know the macs of each ip/macs of each device and...

1. What is the advantage of having multiple networks in the same switch (say 3 nos of 16 port switch) like 192.168.1.x and 192.168.2.x with same mask 255.255.255.0, even though the network has only 40 0r 50 ip devices in the network? Broadcasts will travel everywhere, right? 2. 10.96.209.9 is...

Thanks Bill. Will probe further in this angle, and report soon. 1. I did notice arp table entries with strange IP addresses starting from 77., which the network admin says he has no clue about. It cannot be an internet address since such addresses have no place in the arp cache, right? This IP...

We have a wiznet 5300 ethernet serial-to-modbus network device, and it does not have any DHCP support code inside. I can ping it with a direct cable connection from PC. I can ping it through my switch A. There can be multiple devices in the same switch A belonging to a network, say 192.168.1.x...

There is a network with 2 switches and no routers. The administrator has configured some PCs with 192.168.2.X series and some with 192.168.1.X series. Network mask is 255.255.255.0 - same for all 1. Can 1.X machines ping other 1.X machines? like 192.168.1.2 ping 192.168.1.8 ? 2. 192.168.1.X...
