8.8.3 DHCP Lease Database
8.8.3.1 DHCP Database Agent
The hiD 6615 S223/S323 provides a feature that allows to a DHCP server automatically
saves a DHCP lease database on a DHCP database agent.
The DHCP database agent should be a TFTP server, which stores a DHCP lease data-
base as numerous files in the form of leasedb.MAC-ADDRESS, e.g. leasedb.0A:31:4B:1
A:77:6A. The DHCP lease database contains a leased IP address, hardware address, etc.
To specify a DHCP database agent and enable an automatic DHCP lease database back-
up, use the following command.
Command Mode Description
ip dhcp database A.B.C.D IN-
TERVAL
Specifies a DHCP database agent and back-up inter-
val.
A.B.C.D: DHCP database agent address
INTERVAL: 120-2147483637 (unit: second)
no ip dhcp database
Global
Deletes a specified DHCP database agent.
Upon entering the ip dhcp database command, the back-up interval will begin.
To display a configuration of the DHCP database agent, use the following command.
Command Mode Description
show ip dhcp database
Enable
Global
Bridge
Shows a configuration of the DHCP database agent.
8.8.3.2 Displaying DHCP Lease Status
To display current DHCP lease status, use the following command.
Command Mode Description
show ip dhcp lease {all | bound |
abandon | offer | fixed | free}
[POOL]
show ip dhcp lease detail
[A.B.C.D]
Enable
Global
Bridge
Shows current DHCP lease status.
all: all IP addresses
bound: assigned IP address
abandon: illegally assigned IP address
offer: IP address being ready to be assigned
fixed: manually assigned IP address
free: remaining IP address
POOL: pool name
