Port Security of Access Layer Switches
Port Security is a layer 2 access control feature that allows network administrators to control which devices can connect to a specific switch port. It does this by restricting the MAC addresses allowed on that port and defining how the switch reacts to unauthorized devices. Let's consider the following example. Imagine an open office space with desks everywhere. What stops someone with access to the office from unplugging a device at an empty desk and plugging their rogue device into the wall jack, as shown in the diagram?Catalyst Integrated Security Features (CISF) includes private VLANs, port security, DHCP snooping, IPSource Guard, secure Address Resolution Protocol (ARP) detection, and dynamic ARP inspection.

Summary of Single Busbar Relay Protection
ABB's busbar protection is designed for phase-segregated short-circuit protection, control, and supervision of single busbars. A busbar is a strip or bar of copper, brass or aluminum that conducts electricity within a switchboard, a substation or a battery bank. Its purpose is to conduct a substantial current of electricity. Current Differential Protection: This protection method connects CT secondaries in parallel and. The CT Trouble function in the B30 and B90 relays detects this condition by using a low-set differential element, typically set around 10% of the least heavily loaded circuit connected to the bus, that asserts after a settable time delay. The GRB200 can be applied for single, double and ring busbars with or without transfer busbar, one-and-a-half CB (busbar). Busbar protection (BBP): Protection intended to detect and operate to clear faults on a busbar. [pdf]
