Voice VLAN
Voice VLAN is VLAN configured specially for voice traffic. By adding the ports with voice devices attached to voice
VLAN, we can perform QoS-related configuration for voice data, ensuring the transmission priority of voice traffic and
voice quality.
W
WEP
WEP is an acronym for Wired Equivalent Privacy. WEP is a deprecated algorithm to secure IEEE 802.11 wireless
networks. Wireless networks broadcast messages using radio, so are more susceptible to eavesdropping than wired
networks. When introduced in 1999, WEP was intended to provide confidentiality comparable to that of a traditional
wired network (Wikipedia).
WiFi
WiFi is an acronym for Wireless Fidelity. It is meant to be used generically when referring of any type of 802.11
network, whether 802.11b, 802.11a, dual-band, etc. The term is promulgated by the Wi-Fi Alliance.
WPA
WPA is an acronym for Wi-Fi Protected Access. It was created in response to several serious weaknesses
researchers had found in the previous system , Wired Equivalent Privacy (WEP). WPA implements the majority of the
IEEE 802.11i standard, and was intended as an intermediate measure to take the place of WEP while 802.11i was
prepared. WPA is specifically designed to also work with pre-WPA wireless network interface cards (through firmware
upgrades), but not necessarily with first generation wireless access points. WPA2 implements the full standard, but
will not work with some older network cards (Wikipedia).
WPA-PSK
WPA-PSK is an acronym for Wi-Fi Protected Access - Pre Shared Key. WPA was designed to enhance the security of
wireless networks. There are two flavors of WPA: enterprise and personal. Enterprise is meant for use with an IEEE
802.1X authentication server, which distributes different keys to each user. Personal WPA utilizes less scalable 'pre-
shared key' (PSK) mode, where every allowed computer is given the same passphrase. In PSK mode, security
depends on the strength and secrecy of the passphrase. The design of WPA is based on a Draft 3 of the IEEE 802.11i
standard (Wikipedia)
WPA-Radius
WPA-Radius is an acronym for Wi-Fi Protected Access - Radius (802.1X authentication server). WPA was designed
to enhance the security of wireless networks. There are two flavors of WPA: enterprise and personal. Enterprise is
meant for use with an IEEE 802.1X authentication server, which distributes different keys to each user. Personal WPA
utilizes less scalable 'pre-shared key' (PSK) mode, where every allowed computer is given the same passphrase. In
PSK mode, security depends on the strength and secrecy of the passphrase. The design of WPA is based on a Draft
3 of the IEEE 802.11i standard (Wikipedia)
