Some devices with dual-band wireless network connectivity do not allow the user to select the 2.4 GHz or 5 GHz band (or even a particular radio or SSID) when using Wi-Fi Protected Setup, unless the wireless access point has separate WPS button for each band or radio; however, a number of later wireless routers with multiple frequency bands and ...
Switches bridged (transmitted) L2/Ethernet traffic, and a router forwarded (transmitted and routed) L3/IP traffic. As products became more sophisticated, the distinction between a switch and a router became blurred as high-end switches began to route traffic in addition to bridging, and likewise routers began to perform L2 switching.
Cisco's IOS software maintains one IDB for each hardware interface in a particular Cisco switch or router and one IDB for each subinterface. The number of IDBs present in a system varies with the Cisco hardware platform type. Physical and logical interfaces on the switch will be referenced with either expanded or abbreviated port description names.
The inside of a Cisco 1900-series switch. Catalyst is the brand for a variety of network switches, wireless controllers, and wireless access points sold by Cisco Systems.While commonly associated with Ethernet switches, a number of different types of network interfaces have been available throughout the history of the brand.
On March 30, 2010 Cisco unveiled a new series of home networking products called "Valet". [1] The focus of this series is to simplify the installation and configuration of a typical wireless home network by shipping routers partially pre-configured and bundling with them software that aids the user in setting up their network with a step-by-step wizard.
Network Admission Control (NAC) refers to Cisco's version of network access control, which restricts access to the network based on identity or security posture.When a network device (switch, router, wireless access point, DHCP server, etc.) is configured for NAC, it can force user or machine authentication prior to granting access to the network.
Lightweight Access Point Protocol (LWAPP) is a protocol that can control multiple Wi-Fi wireless access points at once. This can reduce the amount of time spent on configuring, monitoring and troubleshooting a large network. The system will also allow network administrators to closely analyze the network.
The wireless LAN controller is part of the Data Plane within the Cisco Wireless Model. The WLAN controller automatically handles the configuration of wireless access-points. It centralizes wireless network infrastructure and handles bandwidth allocation to the access points (APs).
