Will I have a problem with broadcast traffic with 300+ hosts on the same physical network

Hi Experts, I plan to have 300+ hosts on the same physical network using    192.168.1.x    and    192.168.2.x      Will I experience excessive broadcast traffic?  Is their a better way to do it?   Many thanks

You definitely did not mean /16 aka right.

/23 aka is fine.

Enable portfast and storm control on the switchports.

My network is /22 and thats working just fine.

Sorry, yes I did mean  Please advise the problems?

/16 will give you about 65000 hosts. The larger the number of hosts are, the difficult it becomes to maintain network performance.

You can limit the broadcast using a feature called storm control. 300 host is still good in a single broadcast domain, but definitely not 65000.

Thanks, yes, that was my question, would 300 not be too many because of broadcasts.   Would it not be better to separate them to separate physical networks?
