Switch Security
For the purpose of our discussion here, I will concentrate on the Catalyst 5500 switches. Similar mechanisms can be used to set up security on other types of switches. Switches perform most of their functions at Layer 2 of the OSI model. They often do not participate in Layer 3 and above operations actively. Consequently, access to switches through various Layer 3 and above functions such as Telnet and rsh is very limited. This provides for switch security as well. This section looks at some of the mechanisms you can put into place to further strengthen switch security.
Configuration Management
It is important in switches, as in any other network device, to back up and save the configurations periodically and/or after you make ...
