Is it possible to have wireless & wired client behind a WGB ? This is a query posted in CSC forum given below.

Even I think this is not possible, but when I tried it as shown below proven my assumption was wrong.
So here is the testing topology where WGB (3502-BR2) connecting to root AP using 5Ghz band. Wired clients connecting to R3750 switch connected to G0 of WGB where as Wireless clients are connecting to 2.4GHz radio of WGB (MRN-DATA SSID).
Here is the config of the C3750 where SVI defined for vlan 143.
hostname C3750-1 ! ip dhcp excluded-address 192.168.143.1 192.168.143.50 ip dhcp pool VLAN143 network 192.168.143.0 255.255.255.0 default-router 192.168.143.1 dns-server 192.231.203.132 192.231.203.3 domain-name mrn.com ! interface Vlan143 ip address 192.168.143.1 255.255.255.0 ! interface GigabitEthernet1/0/11 description 1142-BR1 switchport access vlan 143 switchport mode access end
Here is the 1142-BR1 config where MRN-WGB ssid defined to associate WGB.
hostname 1140-BR1 ! dot11 ssid MRN-WGB authentication open authentication key-management wpa version 2 wpa-psk ascii Cisco123 ! interface Dot11Radio1 encryption mode ciphers aes-ccm ssid MRN-WGB station-role root infrastructure-client bridge-group 1 ! interface BVI1 ip address 192.168.143.10 255.255.255.0 ! ip default-gateway 192.168.143.1
Here is the WGB (3502-BR2) configuration where I have defined two SSID, One same name as Root AP to associate to it on 5GHz & the MRN-DATA for users association in 2.4GHz.
hostname 3502-BR2 ! dot11 ssid MRN-DATA authentication open authentication key-management wpa version 2 guest-mode wpa-psk ascii Cisco12345 ! dot11 ssid MRN-WGB authentication open authentication key-management wpa version 2 wpa-psk ascii Cisco123 ! interface Dot11Radio0 encryption mode ciphers aes-ccm ssid MRN-DATA station-role root bridge-group 1 ! interface Dot11Radio1 encryption mode ciphers aes-ccm ssid MRN-WGB station-role workgroup-bridge bridge-group 1 ! interface BVI1 ip address dhcp
Here is the R3750 switch configuration.
hostname R3750 ! interface FastEthernet1/0/10 destcription PC1 switchport access vlan 143 switchport mode access spanning-tree portfast ! interface FastEthernet1/0/11 description 3502-BR2 switchport access vlan 143 switchport mode access spanning-tree portfast
Once you do this configuration & connect wired PC to the R3750 switch in vlan 143 switchport you should see clients are getting DHCP from C3750. Also you should see MRN-DATA wireless SSID is visible & you can connect client using the pre-shared key defined.
Here is client association details on WGB where my iPhone connected to MRN-DATA SSID. You can see WGB itself taken an IP from DHCP on vlan 143.

On Root AP (1142-BR1) you can see all clients behind WGB

Here is the C3750 client information on vlan 143.

You can verify wired device connectivity on R3750 like below.
R3750#sh mac address-table interface f1/0/11 Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports ---- ----------- -------- ----- 143 0000.0c07.ac0a DYNAMIC Fa1/0/11 143 001f.6d21.37cc DYNAMIC Fa1/0/11 143 04f7.e4ea.5b66 DYNAMIC Fa1/0/11 143 44d3.caaf.4343 DYNAMIC Fa1/0/11 Total Mac Addresses for this criterion: 4 R3750#sh mac address-table interface f1/0/10 Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports ---- ----------- -------- ----- 143 001f.1618.dfec DYNAMIC Fa1/0/10 <-Wired PC
I have not tried configuring multiple vlan & see whether it works. You can try it by yourself & see.
