Dhcp port assignment

[Summer10]

I have a switch that I want to act as a dhcp server. And I want some ports on the switch be work in the way that each time a computer connects to lets say port 6, it will get the same ip every time from a dhco pool. Port based address allocation is not an option as this is not working on the IOS(3600 series switch). Is snooping an option? If so, how

As mentioned, port based address allocation is not an option, as these commands are not available for this switch/ios. So need other options

[balaji.bandi]

I may be ignored that message, other options you have with the limited setup like you. ( what version of IOS is this, do you have the option to required IOS to meet the requirement ?)

Reserved the IP address against MAC and put the sticky port only to connect that MAC. (is this works for you ?)

Think it's version 12.2. No new ios versions available I think as this is an old model. As I will not know what computer will connect, using MAC is not an option either. It could be any computer connecting to the port, and I want that computer to receive IP, let's say 10.1.1.100

 Whilst this may sound like talking to an empty bucket; of course if you need such functionalities you need to convince your organisation to provide 'sufficient hardware' for the needed functionality.

Then its limitation of your environment. get better one to meet the feature you looking for,. or live with limited features available to use.

Source or Snoop bind wont work as this I am sure you can only specify a single L3 address to a specific client id so negating the same L3 address being bonded to different L2 addresses so the other option would be dhcp port based allocation but if your device doesn't support this then you I would say you need another device that does.
