Universal client mode is a wireless radio station role that allows the radio to act as a wireless client to another access point or repeater. This feature is exclusive to the integrated radio running in the Cisco 870, 1800, 2800, and 3800 integrated service routers (ISRs).
Universal client mode has the following features and limitations:
•You can configure universal client mode on the main dot11radio interface only, subinterfaces are not supported.
•Universal client can associate to access points with radio VLANs.
•Layer-3 routing is supported over the radio interface. However, there is no support for layer 2 (L2) bridging. The user cannot configure a dot11radio interface with a bridge-group when in universal client mode.
•Service Set Identifiers (SSIDs) are required to be configured on the dot11 interface operating as a universal client; association to an access point running in guest mode is not supported.
•The universal client can associate to Cisco access points, third party access points, and repeaters. It cannot associate to Cisco root bridges or Cisco workgroup bridges.
•Easy VPN does not support universal client mode using DHCP.
