Hi,

We have a DHCP Servers configured in Hot Standby mode (Active Branch Office DHCP Server, Hot Standby Head office DHCP server). Please advice how to calculate the network bandwidth requirement (WAN) in case Branch office Server is powered off.

Both the DHCP Servers are on Win 2012R2, users : 1000 (a

Hi,

You may use Windows Server system built-in Performance Monitor:
Server Manager Tools Performance Monitor

And then click the Add (+) button in Performance Monitor to add a counter to the current Performance Monitor display. Counter belongs to Network Interface and DHCP Server would be helpful for you.

Best Regards,
Eve Wang

Thanks Eve,

would it be possible to calculate the network bandwidth required for new sites specifically from DHCP DORA perspective(in case the Branch office server goes down, all the clients will be requiring ip leases from head office dhcp server over WAN link) : we are coming up with a new site with approx 1000 users with branch office dhcp server on win 2012r2, head office dhcp server - win2012r2

this calcualtion needs to be performed in advance coz we are going to have 24 hours lease duration for ip address,so we have to ensure sufficient bandwidth for dhcp protocol.
