Usage Guidelines
This command removes a host's IP and MAC addresses from the router's internal address tables. This
might be necessary to allow a new host to come online from the previous host's CM.
If the cleared host continues communicating through the CM, the Cisco CMTS adds the host back to its
Note
internal address tables, and the show interface cable interface modem command shows it as having a
"static" address. To block the host from any further access, use the
so that the host cannot access the network unless it obtains an IP address from an authorized DHCP
server.
Examples
The following example shows how to remove a PC's MAC address from the router's internal address
tables on the Cisco CMTS:
