The static-user not-update-ip enable command disables the device from updating IP addresses of static users.
The undo static-user not-update-ip enable command allows the device to update IP addresses of static users.
By default, the device cannot update IP addresses of static users.
After IP addresses for static users are configured, terminals using these IP addresses are authenticated as static users. After these terminals go online, they may send abnormal ARP packets whose source IP addresses are not the IP addresses of static users to the authentication device. After receiving the packets, the device updates terminal IP addresses in CIB entries. As a result, the terminals are no longer static users and go offline. To prevent this problem, you can run the static-user not-update-ip enable command to disable the device from updating IP addresses of static users.
