Universal Client Mode
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 Services Routers. It operates differently from the workgroup
bridge and non-root bridge modes that are supported on other Cisco wireless devices such as the
Cisco
AP 1200.
Universal client mode has the following features and limitations:
• You c an co nfi gu r e un iv e rsa l c li en t mod e on th e ma in dot11radio interface only, sub-interfaces 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 L2-bridging.
The user cannot configure a dot11radio interface with a bridge-group when in universal client mode.
• 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, 3rd party access points, and repeaters. It
cannot associate to Cisco root bridges or Cisco workgroup bridges.
Configuring Universal Client Mode
You c an c onfi gu re un ivers a l c li en t m od e in C isc o I SR series by setting the radio interface station-role to
non-root. This is different from configuring the dot11radio interface to operate in non-root bridge mode,
which requires specifying the word bridge at the end of the command, ex: "station-role non-root
bridge".
Note In other Cisco wireless products such as the Cisco AP1232, station-role non-root operates the same as
station-role non-root bridge. On the ISRs, the two commands are different: station-role non-root is
considered the universal client mode and station-role non-root bridge is considered the non-root bridge
mode.
Example using Cisco 2801 series router:
c2801#conf t
Enter configuration commands, one per line. End with CNTL/Z.
c2801(config)#interface Dot11Radio0/1/0
