DHCP on CISCO 3850

 

I would like to configure the DHCP server on CISCO 3850, and reserve around 100 static IP for servers After doing research found that I need to create an individual pool for each static mapping like below( for 100 static entry 3*100 line of CLI), or is there any better option please suggest?

ip DHCP pool static

host 192.168.1.74 255.255.255.0

hardware-address 0011.f526.516b

i do not see any other option you have, even you use any other DHCP system, still you need to end up entering MAC address manually(since that is unique) so write in notepad and paste save in case if you required to change any MAC address more than 1 device.

Thanks Balaji,

 

Is it possible memory issue because of the long line of code?

Personally i do not use DHCP on the Device, but some situation we use like yours. Since this is not processing much, it only offering DHCP Service and only 300+ lines, should be good.

 

If you have any concernts, start with 100+ and keep adding when there is no issues reported.

Hi @shailendra harinkhede ,

 

These 3 commands are used to assign an IP by DHCP to a specific device.

 

Therefore, you could configure your servers with static IP (bypassing DHCP for this).

Then, make an IP exclusion on your router and start delivering addresses by DHCP from the end of that exclusion.

 

Take it as an option to evaluate

 

Regards
