The following is an example for specifying the range of IP addresses.
SWITCH(config)# service dhcp
SWITCH(config)# ip dhcp pool sample
SWITCH(config-dhcp[sample])# network 100.1.1.0/24
SWITCH(config-dhcp[sample])# default-router 100.1.1.254
SWITCH(config-dhcp[sample])# range 100.1.1.1 100.1.1.100
SWITCH(config-dhcp[sample])#
You can also specify several inconsecutive ranges of IP addresses in a single DHCP pool,
e.g. 100.1.1.1 to 100.1.1.62 and 100.1.1.129 to 100.1.1.190.
When specifying a range of IP address, the start IP address must be prior to the end IP
address.
8.8.1.4 Default Gateway
To specify a default gateway of the DHCP pool, use the following command.
Command Mode Description
default-router A.B.C.D1
[A.B.C.D2] … [A.B.C.D8]
Specifies a default gateway of the DHCP pool.
A.B.C.D: default gateway IP address
no default-router A.B.C.D1
[A.B.C.D2] … [A.B.C.D8]
Deletes a specified default gateway.
no default-router all
DHCP Pool
Deletes all the specified default gateways.
The following is an example of specifying the default gateway 100.1.1.254.
SWITCH(config)# service dhcp
SWITCH(config)# ip dhcp pool sample
SWITCH(config-dhcp[sample])# network 100.1.1.0/24
SWITCH(config-dhcp[sample])# default-router 100.1.1.254
SWITCH(config-dhcp[sample])#
8.8.1.5 IP Lease Time
Basically, the DHCP server leases an IP address in the DHCP pool to DHCP clients,
which will be automatically returned to the DHCP pool when it is no longer in use or ex-
pired by IP lease time.
To specify IP lease time, use the following command.
Command Mode Description
lease-time default <120-2147483637>
Sets default IP lease time in the unit of
second. (default: 3600)
lease-time max <120-2147483637>
Sets maximum IP lease time in the unit
of second. (default: 3600)
no lease-time {default | max}
DHCP Pool
Deletes specified IP lease time.
