All WPS methods are vulnerable to usage by an unauthorized user if the wireless access point is not kept in a secure area. [20] [21] [22] Many wireless access points have security information (if it is factory-secured) and the WPS PIN printed on them; this PIN is also often found in the configuration menus of the wireless access point. If this ...
Wi-Fi positioning system (WPS, WiPS or WFPS) is a geolocation system that uses the characteristics of nearby Wi‑Fi access points to discover where a device is located. [1]It is used where satellite navigation such as GPS is inadequate due to various causes including multipath and signal blockage indoors, or where acquiring a satellite fix would take too long. [2]
The flaw allows a remote attacker to recover the WPS PIN and, with it, the router's WPA/WPA2 password in a few hours. [45] Users have been urged to turn off the WPS feature, [46] although this may not be possible on some router models. Also, the PIN is written on a label on most Wi-Fi routers with WPS, which cannot be changed if compromised.
CDP is also responsible for dynamically communicating the Voice VLAN value from the Cisco switch to the Cisco VoIP Phone. Under Cisco's pre-standard scheme, the PSE (switch) will send a fast link pulse (FLP) on the transmit pair. The PD (device) connects the transmit line to the receive line via a low-pass filter. The PSE gets the FLP in return.
The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0 / 16 (169.254.0.0 – 169.254.255.255) for link-local addressing. [1] The entire range may be used for this purpose, except for the first 256 and last 256 addresses (169.254.0.0 / 24 and 169.254.255.0 / 24), which are reserved for future use and must not be selected by a host using this dynamic ...
Managed switches have one or more methods to modify the operation of the switch. Common management methods include: a command-line interface (CLI) accessed via serial console , telnet or Secure Shell , an embedded Simple Network Management Protocol (SNMP) agent allowing management from a remote console or management station, or a web interface ...
The Xbox One Wireless Adapter for Windows is a USB dongle that allows up to eight controllers to be used at once wirelessly. [70] Per a partnership between Microsoft and Oculus VR, the Oculus Rift CV1 virtual reality headset initially included an Xbox One controller, up until the launch of the Oculus Touch motion controllers. [71]
Cisco Express Forwarding (CEF) is an advanced layer 3 switching technology used mainly in large core networks or the Internet to enhance the overall network performance. . Although CEF is a Cisco proprietary protocol other vendors of multi-layer switches or high-capacity routers offer a similar functionality where layer-3 switching or routing is done in hardware (in an ASIC) instead of by ...
