DHCP configuration is conducted by creating pools and mapping them to L3 interfaces (SVI).
17
Later (when you add a L3 interface and assign an IP address to it), the DHCP Server gets
enabled/started on the interface. If you have a pool for
192.168.0.0/24
, but the L3 interface
is
192.168.0.0/16
, DHCP wont be enabled on 192.168.0.0/16, as it is different from
192.168.0.0/24
.
4. A network pool without any include range is as good as not having a pool at all. Add an include
range using the
address range
CLI command
address range 192.168.0.30 192.168.0.30
5. To work properly, a host pool should have the following 3 items configured:
• client-name ( CLI is
client-name
)
• fixed-address ( CLI is
host
)
• hardware-address/client-identifier
CLI for hardware address is
hardware-address
CLI for client-identifier is
client-identifier
If using
client-identifier
instead of
hardware-address,
the DHCP client sends the
client-identifier when it requests for IP address.
6. A host pool should have its corresponding network pool configured, otherwise the host pool is
useless. The fixed IP address configured in the host pool must be in the subnet of the
corresponding network pool.
7. Use the global configuration mode
service dhcp
to enable/disable the DHCP Server. This
enables/disables the DHCP Server on all interfaces.
8. If you create a pool and map it to interface, it automatically gets enabled, provided DHCP is
enabled at the global level. Use the
no network
command to disable DHCP on a per
pool/interface basis.
9. To add a newly created pool to the network pool, use one of the following:
• network ( Eg network 192.168.0.0/24 )
• address range ( Eg address range 192.168.0.30 192.168.0.50 )
10. To add a newly created pool to host pool, use one of the following:
• host ( Eg host 192.168.0.1 )
• client-name ( Eg client-name "kaveri" )
• client-identifier ( Eg client-identifier "aabb:ccdd" )
• hardware-address ( Eg hardware-address aa:bb:cc:dd:ee:ff )
11. A pool can be configured as the host pool or network pool, but not both.
12. A host pool can have either
client-identifier
or
hardware-address
configured, but not
both.
13. An excluded address range has higher precedence then an included address range. If a range
is part of both an excluded and included address range, it will be excluded.
14. DHCP options are first defined at the global level, using
ip dhcp option
. The value for these options are associated using the
option
which is under DHCP pool
context.
