NETWORK SWITCHES WITH SECURED SWITCH PORTS TO BASEBOARD MANAGEMENT CONTROLLERS

Abstract:

A server management switch discovers and identifies its switch ports that are connected to communication ports of baseband management controllers (BMC's) of server computers. The server management switch isolates the identified BMC-connected switch ports such that network traffic on a BMC-connected switch port is restricted to a switch port that has a connection, either directly by a link or over a server management network, to a server management computer. Network traffic on BMC-connected switch ports are monitored and controlled in various ways to further protect the BMC's from security attacks.
