Some background information of my current configuration.
VLAN 100
-Computer A
interface gi1/1/1
[Code]....
From computer A, i had run command prompt and ping 192.168.2.100(computer B) and successfully get a response. I had repeated the step but ping to a broadcast address (192.168.255.255) and it was unsuccessful.
we manufacture an industrial device that runs embedded linux, and we are throwing ideas around on how we can find devices that are connected to our network, without knowing their ipAddress. I know this is possible, because Advantech do it with their ADAM utility to find units. I put a WireShark sniff on my LAN as the ADAM Utility found a unit, and saw the following[CODE]

View 2 Replies View RelatedI know very little about switches. This is the first time I've ever touched them. However, I'm the only one in the company who has the slightest knowledge on how to make them work.
4 vlans
vlan 1 - 192.168.32.1 - Existing network with Internet access
vlan 33 - 192.168.33.1
vlan 34 - 192.168.34.1
vlan 35 - 192.168.35.1
From the laptop on vlan 33 I can ping the management interfaces (192.168.x.1) for each of the vlans. However, I cannot ping anything on those networks.
Below is what I have with the config. Right now not much attached to these switches until they are setup.

I have the new firmware running on my SG500 switch. I've also just finished creating my VLANs. My issue is that I can't delete the old default VLAN .... VLAN 1. More importantly, I can't seem to get DNS to work on the switch.
When I set a DNS server, the VLAN defaults to VLAN 1, and the option is greyed out and can't be changed. Why is it VLAN1? Why is it greyed out? How do I get DNS to work on the switch, for services like Time Servers?
I have an SG500 that is already deployed with some Access VLANs on it. The PVID is still the default 1. I am trying to change it to 19 with as little interruption as possible. If I just go to the VLAN Management Tab and change the Default VLAN to 19 and reboot the switch, will it migrate my management IP to the default VLAN without any trouble? Would it be less interruption to: Create VLAN 19, assign it an out of subnet IP address, change a port to PVID 19, connect directly to that port, go to that IP address, remove the original management IP from PVID1, change all the ports to PVID19 then change the management IP back to the original?

I recently bought SG-300 28P to create the VLAN. My network hs 3 subnet 192.168.1.0, 192.168.2.0 and 192.168.3.0.My main net work is 192.168.1.0. I want to divide it to VLAN to eliminate the boardcast storm; especially from the domain 192.168.3.0
But I want all the devices from 192.168.1.0 to access other subnet.

version: 1.1.0.73
Switch is running in layer 3 mode.How can I turn off mDNS broadcast coming from the vlan interface on the switch.Getting mDNS broadcast from switch every 5 seconds.
We run a network of several 2960G and 3650G switches in a network with a number of VLANs. One one particular VLAN (let's call it VLAN 10) it appears that non-broadcast traffic (i.e. normal unicast traffic) is being copied to every port in VLAN 10 only on one switch . The traffic is not crossing trunk ports and does not appear on other switches that have ports in VLAN 10. We first spotted this by noticing that a UPS port had an unusual amount of activity on our port througput graphs:
This traffic at 4 am is not expected and this profile is repeated across all ports in VLAN 10 on this switch (a WS-C2960S-48TD-L stack running IOS 15.0(1)SE3)\iffed one port using local SPAN (the UPS port) and discovered that this traffic was not broadcast, which was running at a normal low rate at all times. The traffic appeared to be unicast traffic from other ports of the sort you might see on a hub. It was from various hosts that live on VLAN 10, most (not all) of the conversations had one end station homed on the 'problem' switch. There are about 800 non-broadcast packets per hour and this is a busy VLAN so it does not account for all the traffic on the VLAN.
I have cisco switch model WS-C3750G-12S-D. It is in transparent mode. I am getting below error message when tried to create new vlan.
Proposed configuration exceeds the limit of 1005 VLANs that can be supported on this platform. Reduce the number of VLANs proposed to be within this limit.
After deleting few unnecessary vlans, it allowed me to create.

I confused with terms 'maximum supported vlans' and 'maximum locally supported vlans'. If switch is supporting vlans 1-4094 means it should also allow to create locally. Otherwise how they will pass through the switch trunks without local creation.
I recently upgraded my network to have two 3750x core, one interface on the Cisco is connecting to a Net gear switch via a fiber converter. I am keep getting the vlan flapping error message in my log as below.

After my research i think this is a looping issue but I'm unsure how to address it.
I require a system that will support 3 VLANs, the VLANs are purely for containment of broadcast traffic and needs to support inter-VLAN communication between client devices. Would the following configuration work:
Port based VLAN on the SRP527W with each port connected to layer 2 switches serving each VLAN.
DHCP server on the SRP527W assigning IP addresses for each of the V LANS in different ranges. (eg 10.10.1.xx, 10.10.2.xx, 10.10.3.xx). Would there be any benefit upgrading the Router to a SRP547W?
I recently bought an RVS4000, and unfortunately forget the "if it ain't broke, don't fix it" rule, and flashed it to the latest firmware (2.0.2.7). Subsequent to doing that, it has been inconveniently dropping the connection to my ISP and completely locking itself up to a point where a manual reboot is required, usually about 4 hours after any outgoing activity (which usually means 11pm!).
Goggling my way round seems to suggest that this could be a firmware problem. The accepted wisdom is that I need to use the RVS4000 Upgrade Utility to get back to a lower version, so I have downloaded and installed V1.3 from the RVS4000 support area. However, though I think I followed the instructions (including trying setting the host PC to a fixed IP address, which was not supposed to be necessary), but I am consistently getting a "Broadcast Error" message, which I am guessing means that the utility and the RVS4000 aren't talking.
I live in an area where there are lots of wireless modems and since most broadcast on the default frequencies, here is often interference. I'd like to set my AC900 to broadcast on a fixed channel that is not often used, e.g. 2 or 3 or 8.

Same problem ' network cable unplugged' even if it is physically connected. I have sony vaio pczim series with win 2000 xp home edition with a broadband (cpe adsl2+ type) connection. While everything working fine for past two years, suddenly after a thunderstorm night, I noticed the network connection failure with the message. I checked the router, cable and the same are working fine with other hp laptop. Even the vaio is running with the same router while usb port is used and even the wireless and bluetooth are fine, but network with ethernet cable connection does not.

I was looking for a small business router that has VPN support and dual WAN support for load balancing. Upon reading reviews, I think RV042/RV042G is a good choice. Now am thinking if it supports intervlan/ router-on-a-stick configuration?
