Workgroup bridge

As explained in Acing the CCNA Exam: Volume 2 Advanced Networking and Security

A workgroup bridge is an access-point operating mode that connects one or more wired devices to a wireless LAN through a wireless client connection.

A workgroup bridge (WGB) lets wired devices join a wireless LAN when cabling to a switch is impractical. The wired device connects by Ethernet, while the WGB operates as a wireless client of a main access point on its behalf. section 18.4.2

Key operating facts:

  • A WGB can support multiple wired devices when the main access point is Cisco. section 18.4.2
  • A non-Cisco main access point requires Universal WGB mode, which supports only one wired device. section 18.4.2

Typical deployment

AP2 operates in WGB mode and connects by wireless to AP1. PC1, which lacks wireless capability, connects to AP2 by Ethernet and reaches the wireless LAN through AP1.

How Acing the CCNA Exam: Volume 2 Advanced Networking and Security covers it

How deep it goes
Defines Ethernet attachment, wireless client behavior, device capacity, and Universal WGB limitations without configuration commands.
Examples
Uses AP2, AP1, and Ethernet-connected PC1 to illustrate a wired client reaching the wireless LAN.
What it assumes
Assumes a wired device, an Ethernet connection, and a wireless LAN with a main access point.
What you can do after
Evaluate when a WGB or Universal WGB deployment can connect wired devices through a wireless access point.
How it connects
Links access points, wireless LANs, Ethernet connections, wireless clients, and Universal WGB mode.
