4Mbps Bandwidth of Internet is provided to my company by the ISP. When I check the speed of the internet at the inside interface of the Juniper firewall I get around 3.4 Mbps. The Juniper is connected to two Catalyst 4507 Core switches, which is then connected to 3560 Access Switches. The users connected to the Access Switch only gets an internet speed of 500kbps. The drop seems to be happening at the Core Switches. How can I verify and determine what is causing this slow speed??
Thanks in Advance.
