Hi,

What if suddenly the DHCP server fails, how do u handle users? What will be quick solution? Assume there are about 500 users connected to server.

Hello,

Well, how fail? Where is your server setup? Have you a dhcp failover? It is under which OS? Windows, Linux, L3 Switch?

About your topology environment? Could you draw a simple exemple about your environment?

There are many ways to handle it, but to suggest a better solution for you, we need more information about your environment/topology.

Hi,

Pls assume that only lone DHCP server connected to hosts fails, what will
be the quick resolution to provide ip for hosts?

Hi @suresh.nr3171 

You can create the DHCP pool in a network device, such as a router or an L3 switch.
This could work until the DHCP server problem is resolved.

It all depends on how you design the DHCP Server in the environment, is the high availability required for business yes or no. ( Costing and so on the factor to take into accounts)

Technically you need to set up 2 DHCP Servers always, so one fails another one automatically serves the purpose.

make sure you split the IP to 2 DHCP Servers.
