Please add DHCP reservation feature to switch M4300

As the core of LAN, L3 switch really needs DHCP reservation, which is indispensable. It's well-known that switch is the most stable hardware in network. It's more likely for a bare-metal server goes down than a switch does. If M4300 has DHCP reservation feature, we can transfer the DHCP server from a PC to the switch, which could enhance the stability and convenience for management of the network significantly.

At present, in "System-Services-DHCP Pool Configuration", I have to create ONE "manual_pool" for EACH MAC-IP mapping. It's REALLY tedious and boring. I think you can add at least two features to improve the situation.

1. Re-design "System-Services-DHCP Pool Configuration-Type of binding-manual" in the web-gui, and allow people to add multiple MAC-IP-GATEWAY-DNS-NETBIOS mappings to one 'manual_pool'. For example:

In this way, users can easily add or remove records by clicking the '+' or '-' button ahead of each line.

2. Add a new command to load an external text-based datebase which contains all the information stated above from a USB flash drive or tftp server. In this way, users can create and modify the text-based database using their favorite text-editor and then upload it to the switch.

It would be great if the developers can add the features I stated above to M4300.

Thanks a lot.
