System information

Configuring the CMTS
6-129
• Use the show cable modem stats command in Privileged EXEC mode to display
IP statistics for the number of unicast bytes that are transmitted and received for
each CM MAC address on a cable module, which includes CMs that are off-line,
as shown below
MOT#show cable modem [<mac> | <0-15> | <prefix>] stats
where:
mac is the MAC hardware address of the CM.
prefix is the IP address of the CM.
0-15 is the slot number of the cable module to which CMs are associated.
Figure 6-27 displays transmit bytes, receive bytes, and registration CM statistics
for a cable module slot.
Figure 6-27 show cable modem stats Command Output
Displaying Modulation Profiles
A modulation profile contains six burst profiles sent out in a UCD message to
configure CM transmit parameters. To display modulation profile group information,
use the show cable modulation-profile command in Privileged EXEC mode, as
shown below:
MOT#show cable modulation-profile
Table 6-13 describes the fields in the show cable modulation-profile command
display.
