Usage Guidelines
This feature speeds up the frequency search performed by the cable access router. Normally it takes
the cable access router about 30 to 50 seconds to sample 30 to 50 frequencies. The cable-modem
fast-search command can reduce this search time. However, there might be some cases where this
fast-search algorithm might not perform as well as the default algorithm. Trial and error is the only
way to discover how well this feature works for your environment.
Examples
The following example shows how to enter the cable-modem fast-search command, starting from
global configuration mode:
cable-modem fast-search
no cable-modem fast-search
uBR924(config)# interface cable-modem 0
uBR924(config-if)# cable-modem fast-search
uBR924(config-if)#
