However, additional configuration information may be needed to complete the Wideband SPA configuration process. For information on Wideband SPA configuration procedures, see the Cisco uBR10012 Universal Broadband Router SIP and SPA Software Configuration Guide. show hw-module bay To display additional information about a wideband channel, use the show hw-module bay command with the wideband-channel keyword. You also have to specify one of the following keywords indicating the particular type of information you want to show: OL-10705-02 Cisco Cable Wideband Solution Design and Implementation Guide, Release 1.0 5-7
