Managing Leases

Historical DHCP lease records complement the real-time DHCP lease viewer by allowing the appliance to store and correlate DHCP lease information over the lifetime of a lease. You can see critical information such as when the appliance issued or freed an IPv4 or IPv6 address, the MAC address or DUID and host name of the device that received the IP address, the Grid member that supplied the lease, and the start and end dates of the lease.

You can view current leases and lease history in the Data Management -> DHCP -> Leases tab in Grid Manager. To view lease history, you must first enable lease logging at the Grid level. For information, see Configuring DHCP Logging and Configuring the Lease Logging Member. You can also export the DHCP lease history log in CSV format for archival and reporting purposes.

In the Leases tab, you can do the following:

View current leases. For information, see Viewing Current Leases.
View detailed information about a specific lease. For information, see Viewing Detailed Lease Information.
View historical lease records. For information, Viewing Lease History.
Export current leases and lease history logs. For information, see Exporting Lease Records.
Clear leases. For information, see Clearing Leases.

You can also use the filter and Go to functions in the lease panels to retrieve lease information for specific hosts, MAC addresses, and IP addresses. These capabilities are crucial for security auditing and for meeting new compliance regulations such as SOX and HIPAA. You can also sort the lease information by column.
