Syntax Description

Command Mode
Privileged EXEC
Usage Guidelines
This command first appeared in Cisco IOS Release 11.3 NA.
This command shows the details of the lookup table. The driver uses this table to convert the size of
a frame that the cable modem wants to transmit into a bandwidth request to the CMTS in
“mini-slots.” The contents of this table are affected by the upstream symbol rate that is negotiated
between the CMTS and the cable modem.
This command is only useful for development engineers.
Sample Display
The lookup table is displayed in the following example:
uBR904# show controller cable-modem 0 lookup-table
