broadcast traffic
Hi,
I'm a network administrator in my new job and when I ran Wireshark I saw to
much ARP traffic level and Ntop show 86% broadcast traffic to.
There are DHCP server and 350 Windows stations. My boss dont know nothing about
networks and I propose to my boss buy a layer 3 switch and create vlans to
reduce the broadcast traffic levels, but my boss ask what must be the normal levels of broadcast traffic in the LAN network. I have search in google and I can't find a good response
to that question, I feel bad without a good answer and reference.
Could any in the list help me please?
Thanks for your time and excuse my english.
joans4nz.
