802.11 standarda, b, g, and n802.11a, 802.11b, 802.11g, and 802.11n.80211.b operates in the 2.4 GHz range. Within its RF band, the 802.11b standard defined 14 channels.802.11a uses a different RF band (5 GHz)802.11g was the next revision adopted. This standard matches the speed of 802.11a but is compatible with 802.11b.802.11n :Operating in both the 2.4 and 5 GHz bands, 802.11n is backward compatible with 802.11a/b/g.Wireless networks use the 2.4-GHz band and the 5-GHz band. The 5-GHz band hasslightly less coverage than the 2.4-GHz band.Standalone (autonomous) APs: Can be configured one by one and offer full functionality by themselves (they are welladapted for small deployments.Lightweight APs: Rely on a central WLAN controller where the configuration is managed. Most APs can be converted fromone mode to the other depending on the specific deployment needsHP FlexNetwork Architecture is a network architecture developed by HP to provide networking services and a consistent network architecture for the data center,campus and branch offices. It was developed to support technologies such as virtualization and cloud computing.Components of Building an SDNProVision# configProVision(config)# hostname ProVision(config)# vlan 1ProVision(vlan-1)# ip address /Heres a simple example:ProVision(config)# vlan 1ProVision(vlan-1)# ip address 192.168.1.254/24ProVision# show running-configSwitch(vlan-1)# write memorySwitch# erase startup-configProVision(config)# interface ProVision(eth-)# ProVision(config)# interface < port-list > [disable | enable ]ProVision> show interface []show nameshow interfaceshow running-configProVision> show interface []
