Basic Service Set
The IEEE 802.11 BSS of an AP comprises of the
stations directly associating with the AP.
Wireless clients found to be running outdated/
unsupported virus software and not compliant to
network admission control guidelines need to be
placed on different VLANs than the intended normal
VLAN. These VLANs on which the non-compliant
clients are placed are termed as Backup VLANs.
Backup VLANs are used to quarantine the
non-compliant clients running incorrect software
till they upgrade their software to the correct
Device that connects two or more segments
and reduces traffic by analyzing the
destination address, filtering the frame,
and forwarding the frame to all connected
It is an AP that functions as a transparent
bridge between 2 wired LAN segments.
Clients can send out Broadcast SSID Probe
Requests to a nearby AP, and the AP will
broadcast its own SSID within its beacons
to response to clients. Clients can use this
Broadcast SSID to associate and communicate
with the AP.
Extensible Authentication Protocol
EAP acts as the interface between a wireless
client and an authentication server, such as a
RADIUS server, to which the access point
communicates over the wired network.
Standard to encourage interoperability among
wireless networking equipment.
High-rate wireless LAN standard for wireless
data transfer at up to 11 Mbps.
Higher Speed Physical Layer (PHY) Extension to
IEEE 802.11b, will boost wireless LAN speed to 54
Mbps by using OFDM (orthogonal frequency division
multiplexing). The IEEE 802.11g specification is
backward compatible with the widely deployed IEEE
The IEEE 802.11 standard does not define how
access points track moving users or how to
negotiate a handoff from one access point to the
next, a process referred to as roaming. IAPP is
a Cisco proprietary protocol to support roaming.
However, IAPP does not address how the wireless
system tracks users moving from one subnet to
Network that provides peer-to-peer connectivity
without relying on a complete network
Optional wireless network management data element
in the beacons and probe responses generated by
wireless stations. These elements identify the
extended capabilities supported by the stations.
Integrity Check Value
The WEP ICV shall be a 32-bit value containing
the 32-bit cyclic redundancy code designed for
verifying wireless data frame integrity.
Message Integrity Check
A MIC can, optionally, be added to WEP-encrypted
802.11 frames. MIC prevents attacks on encrypted
packets. MIC, implemented on both the access point
and all associated client devices, adds a few bytes
to each packet to make the packets tamper-proof.
An access point radio broadcasts and advertises
multiple SSIDs in the beacons. For clients'
prospective, it is like there are multiple access
points existing in the wireless network.
Native VLAN ID
A switch port and/or AP can be configured with a
'native VLAN ID'. Untagged or priority-tagged
frames are implicitly associated with the native
VLAN ID. The default native VLAN ID is '1' if
VLAN tagging is enabled. The native VLAN ID is '0'
or 'no VLAN ID' if VLAN tagging is not enabled.
This wireless bridge does not connect to the main
wired LAN segment. It connects to a remote wired
LAN segment and can associate with root bridges and
other non-root bridges that accept client
associations. It also can accept associations from
other non-root bridges, repeater access points,
and client devices.
In an AP, if the destinations of inbound unicast
frames are unknown, the frames are sent toward
the primary LAN defined on the device.
Device that connects multiple segments,
listening to each and regenerating the signal
on one to every other connected one; so that
the signal can travel further.
Repeater or Non-root Access Point
The repeater access point is not connected
to the wired LAN. The Repeater is a wireless
LAN transceiver that transfers data between
a client and another access point, another
repeater, or between two bridges. The repeater
is placed within radio range of an access point
connected to the wired LAN, another repeater, or
an non-root bridge to extend the range of the
Radio wave and modulation process or operation.
Root Access Point
This access point connects clients to the main
Root (Wireless) Bridge
This wireless bridge connects to the main wired
LAN. It can communicate with non-root wireless
bridges, repeater access points, and client
devices but not with another wireless root
bridge. Only one wireless bridge in a wireless
LAN can be set as the wireless root bridge.
Service Set ID
SSID is a unique identifier that APs and clients
use to identify with each other. SSID is a simple
means of access control and is not for security.
The SSID can be any alphanumeric entry up to 32
VLAN defined in the IEEE 802.1Q VLAN standard
supports logically segmenting of LAN
infrastructure into different subnets or
workgroups so that packets are switched only
between ports within the same VLAN.
Each VLAN is identified by a 12-bit 'VLAN ID'.
A VLAN ID of '0' is used to indicate
'no VLAN ID'. Valid VLAN IDs range from '1' to
'4095'. VLAN of ID '4095' is the default VLAN
for Cisco VoIP Phones.
Wired Equivalent Privacy
WEP is generally used to refer to 802.11
