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.

What material is the yellow outer layer of the optical cable made of
Kevlar® is the registered trademark for the strong synthetic material or yellow 'hair' used as a protective outer sheath for the glass fiber core it protects. Its high tensile strength protects the cable from damage when being pulled. Structurally, a fiber cable comprises the core, cladding, coating, strength member, and outer jacket. The fiber jacket protects against moisture, UV exposure, chemicals, and mechanical abrasion. Larger core sizes allow a larger amount of light, or a larger beam diameter, to enter the fiber. The numerical aperture. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. Many factors influence the design of fiber-optic cables. [pdf]
