Once Bridge mode is enabled, the VLAN tagging option will be available.
It is recommended to enable VLAN tagging for the SSID.
If VLAN tagging is utilized, ensure that the Cisco Meraki access point is connected to a switch port configured for trunk mode

On the Wireless > Configure > Access control page, the frequency band for the SSID to be used by the Cisco IP Phone 8861

It is recommended to select 5 GHz band only to have the Cisco IP Phone 8861 and 8865 operate on the 5 GHz band due to
have many channels available and not as many interferers as the 2.4 GHz band has.
If the 2.4 GHz band needs to be used due to increased distance, then Dual band operation (2.4 GHz and 5 GHz) should be
selected. Do not utilize the Dual band operation with Band Steering option.
Is recommended to disable data rates below 12 Mbps unless a legacy 2.4 GHz client needs to be able to connect to the Wireless
LAN.
Cisco Meraki access points currently utilize a DTIM period of 1 with a beacon period of 100 ms; which both are non-
