Tip
If you encounter apparent problems with secondary IP addressing, or if you want to manually clear the
table of IP addresses for a particular SID, use the clear cable secondary-ip command.
Tip
One possible situation that might occur is if a CM first assigns a secondary IP address to one CPE device,
but later that same IP address is assigned to another CPE device behind a different CM. If this happens,
the IP address will continue to show up as a secondary IP address for the original CM until that CM
renews its public keys. This will not affect network connectivity for either CPE or CM. You can,
however, clear the unneeded secondary IP address from the CMTS database using the clear cable
secondary-ip command.
Examples
The following example shows how to clear all of the secondary IP addresses for a particular cable
interface:
Router# clear cable secondary-ip interface cable 3/0 all
Router#
The following example shows how to clear the secondary IP addresses for all CM and CPE devices on
cable interface 1/0 that are using SID 5:
Router# clear cable secondary-ip interface cable 1/0 sid 5
Router#
The following example shows how to clear the secondary IP addresses for the CM and CPE devices on
cable interface 5/0 that are using SID 113 and IP address 10.10.17.3:
Router# clear cable secondary-ip interface cable 5/0 sid 113 10.10.17.3
Router#
