We have a network with 300 Clients, lately - we been witnessing large network connection drops and slow down of network.
The hardware and network configuration didn't change, what's the best way to troubleshoot these issues. After some initial investigation found out the network was amplifying broadcast packets. How do I stop it, Have a CISCO PIX Firewall 515E acting as gateway.
# ping -c 10 -s 1 -q -b 10.0.255.255
