    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.

  6. Port Aggregation Protocol - Wikipedia

    en.wikipedia.org/wiki/Port_Aggregation_Protocol

    A limitation of Port Aggregation Protocol is that all the physical ports in the aggregation group must reside on the same switch. Cisco's 6500 and the 4500E platforms, remove this limitation using Virtual Switching System (VSS), [1] which allows port channels to be split between two chassis. PAgP is not supported in Cisco Nexus Switches.
