I'm in need of a device which can switch to several items which has the same mac address. I heard that there may be devices that can handle this, by for example mapping fake unique mac addresses in the switch to each on of the same mac addresses on the devices, so when you try to send something to a "device with the same mac address" you send it to the faked address in the switch and the switch just forwards it.

View 1 Replies View RelatedI reset my Dlink 615 wireless router. I held down the power and reset for 30 seconds and rebooting the system with the disc. I did change the router name, but believe everything else stayed the same. My desk top is working fine being "hardwired" but nothing wireless will connect.
I did see this time it installed Network Magic which I have since uninstalled and again rebooted the computer system and still cannot get the wireless to work. It shows the network available, but my password for some reason does not take.
We are running ACS 5.2 patch 6 and want to restrict access for users to be able to add devices to the system.For example, admin person in site A can only add devices into the site A group and cannot see/access other sites groups.

My ISP assigns IP's through a standard motorola cable modem via DHCP server. I can pay extra for a persistent IP which uses the MAC of my switch and assigns an IP. Is there a way to get multiple public IP address's from the modem using a switch?For example. Can I plug the modem into the switch and then plug a computer server into the switch and get an IP assigned to that servers MAC address and then also have another server attached to another port on the switch and get a different public IP for that servers MAC address?

What I need to know is how to add the IP address helper command to the switch?I have a number of IP phones which are not getting an IP address from DHCP (PCs which are diasy chained off the phones are all working correctly). On the higher end switches I would have added the IP address helper command to the VLAN and that would have sorted it. How to do this on the small business switch.

Switch is a Nortel 5520
PC is Windows 7, with Intel 82579LM adapter
When PC was first attached to network, it could not ping gateway(switch). Turns out it was broadcasting for the gateway's MAC address, but never got a response. Tonnes of testing later, if I just change one number on the MAC address of the adapter, it receives a reply from the switch and can ping the gateway.
Why doesn't the native MAC address work?
Update: Just the vendor portion is the determining factor. As long as it starts with 2C-59-E5, it will not work. 2C-58-E5 will.
Update 2: Pinging anything in the same subnet works, just pinging the gateway interface of the switch doesn't happen. Tried on multiple drops, and there are other devices on those drops.
I would like to know if ip helper-address feature is working on a layer 2 switch (2950,2960) or you should use a Layer 3 switch to do that?
