Port Security of Access Layer Switches

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.

Adjustable power supply for testing laser diodes

Adjustable power supply for testing laser diodes

These current sources are designed for testing and controlling multiple high power laser diodes with specially designed features such as high set-point accuracy, low output noise, forward voltage, and photodiode measurement and an adjustable photodiode reverse bias voltage. While a laser diode driver is the safest and most effective method for powering a laser, in some cases, a bench power supply may be an option. They feature an on-board 12-turn trim pot for continuous laser power output adjustment, pin-programmable feedback gain, ON/OFF control. [pdf]
