Association Request/Response

 Association Request:

Type: 00

Subtype: 0000

    The association request frame is the next step when joining the BSS after the Authentication frame exchange. The association request contains important information like Capability Information, Listen Interval, SSID, Supported Rates and Extended Rates, Channels Supported and QoS capability. The point of the association request frame is to advertise the capabilities of the client to the AP that match what the AP advertised in the beacon or probe response frames.


Pictured is the association request frame format:





Association Response:

Type: 00

Subtype: 0001

    If the capabilities of the client match the required capabilities of the AP, the AP will send an association response frame with the status code of Successful and with an Association ID for the specific client. All clients in the BSS receive a specific association ID.

Following Design Processes

    It is important to use proper design methodology when designing wireless networks. WiFi has evolved numerous times since it was first implemented, yet I still see very outdated or flat out wrong ways of designing a wireless network. The biggest thing I find is that many places do not follow the design process when choosing to install a new or update an existing WLAN. Essentially we are throwing hardware at a design problem and expecting it to work. In this post, I'll cover the proper way to design a wireless network according to CWNP's guidance. Thank you CWDP-303 official study guide from CWNP for providing me with the ability to do so!  Define     This might be one of the most overlooked parts of the design process. This step in the process sets the foundation for a good, well thought out design. Instead of simply getting a floor plan and jumping straight into a network planner, let's understand who or what we are designing for. During this stage, meeting ...

ExtremeCloud IQ Instant Port

Image
Instant Port enables you to automate your access layer by dynamically assigning VLANs based on the end devices MAC and/or LLDP capabilities. This document will cover the configuration of instant port and show an example.   Configuration of Instant Port is simple. First, create an Instant Port Profile within your network policy then assign that profile to your Switch Template.   ·          The Non-Forwarding VLAN will be used by default to learn the MAC and LLDP capabilities of the end device. ·          The Default Port Type will be used if you wish to provide non-matching devices layer two connectivity. ·          You can choose whether to allow non-matching devices to use either the Default Port Type or the Non-Forwarding VLAN. By using the Non-Forwarding VLAN, unknown devices will be dropped in an unused VLAN without the ability to reach other ...
