Limiting the Number of IP Addresses Supplied by DHCP Local Server

474
If you do not specify a mode, equal-access mode is activated, by default. When you
activate equal-access mode, common open policy service usage for policy provisioning
(COPS-PR) and SRC client are automatically started on the virtual router.
To configure the DHCP local server:
Enable the DHCP local server for either equal-access or standalone mode.
1.
host1(config)#service dhcp-local equal-access
host1(config)#service dhcp-local standalone
(Optional) Specify the maximum number of IP addresses that the DHCP local server
2.
can supply to each VPI/VCI, VLAN, Ethernet subnetwork, or to a particular interface
or subinterface. See "Limiting the Number of IP Addresses Supplied by DHCP Local
Server" on page 474 for more information about limiting the number of IP addresses.
host1(config)#ip dhcp-local limit ethernet 6
(Optional) Specify any addresses that the DHCP local server must not assign. See
3.
"Excluding IP Addresses from Address Pools" on page 475 for more information.
NOTE: You can specify this command multiple times on the CLI and the
excluded address must fall within a network that has been specified in
the DHCP local pool.
host1(config)#ip dhcp-local excluded-address 10.10.3.4
(Optional) Enable general DHCP local server traps. See "Using SNMP Traps to Monitor
4.
DHCP Local Server Events" on page 478.
host1(config)#ip dhcp-local snmpTraps
(Optional) Configure the DHCP local server to support the creation of dynamic
5.
subscriber interfaces built over dynamic VLANs that are based on the agent-circuit-id
option (suboption 1) of the option 82 field in DHCP messages. See "Configuring DHCP
Local Server to Support Creation of Dynamic Subscriber Interfaces" on page 475.
host1(config)#ip dhcp-local auto-configure agent-circuit-identifier
(Optional) Specify that DHCP local server use an optional method to differentiate
6.
between clients with duplicate client IDs or hardware addresses. Any changes you
make have no effect on currently bound clients. See "Differentiating Between Clients
with the Same Client ID or Hardware Address" on page 476.
host1(config)# ip dhcp-local unique-client-ids
Configure the DHCP local address pool that supplies IP addresses to subscribers who
7.
want to access a domain. See "Configuring DHCP Local Address Pools" on page 480
for more information about configuring address pools.
You can specify the maximum number of IP addresses that the DHCP local server can
supply to each VPI/VCI, VLAN, Ethernet subnetwork, or POS access interface type, or to
a particular interface or subinterface.
