Check Text ( C-7480r3_chk )
Verify the DHCP audit and event logs include hostnames and MAC addresses of all clients. Also, validate logs are kept online for thirty days and offline for one year. If the logs do not include hostnames and MAC addresses or if the logs are not kept online for thirty days and offline for one year, this is a finding.
