Command Reference

show controller cable-modem lookup-table

To display the mini-slot lookup table inside a cable modem, use the show controller cable-modemlookup-tablePrivileged EXEC command.

show controller cable-modem lookup-table

Syntax Description

This command has no keywords or arguments.

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:
