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.
