SNMP Thresholds

Configuring a Local Address Server

54
An address pool has SNMP thresholds associated with it that enable the local address
server to signal SNMP traps when certain conditions exist. These thresholds include high
utilization threshold and abated utilization threshold. If a pool's outstanding addresses
exceed the high utilization threshold and the SNMP trap signaling is enabled, SNMP is
notified. Likewise, when a pool's utilization drops below the abated threshold utilization
threshold, SNMP is notified.
You can create, modify, and delete address pools. You can display address pool
information or status with the show ip local pool command. The following are examples
of tasks you can configure:
Specify an addressing scheme.
host1(config)#ip address-pool local
Map an address pool name to a range of local addresses. You can also use this
command to add additional ranges to a pool.
host1(config)#ip local pool addrpool_10 192.168.56.10 192.168.56.15
Map a primary local address pool name to a domain name.
host1(config)#aaa domain-map westford.com
host1(config-domain-map)#address-pool-name poolA
(Optional) Map a backup address pool to a domain name, which is used for address
allocation if the primary local address pool is fully allocated.
host1(config)#aaa domain-map westford.com
host1(config-domain-map)#backup-address-pool-name backup_poolB
(Optional) Map the domain name to the IPv6 local address pool, which is used for
prefix delegation. If the authentication server returns the prefix pool name in the
Framed-Ipv6-Pool attribute of the RADIUS-Accept-Request message, this value
overrides the IPv6 local pool configured using the ipv6-prefix-pool-name command.
host1(config)#aaa domain-map westford.com
host1(config-domain-map)#ipv6-prefix-pool-name local_addr_pool
Delete an address pool.
host1(config)#no ip local pool addrpool_10
NOTE: If a pool or range is deleted and addresses are outstanding, the AAA server logs
out the clients using the addresses.
Create a shared local address pool.
host1(config)#ip local shared-pool Shared_LAS_Pool_A DHCP_Pool_1
Delete a shared local address pool.
host1(config)#no ip local shared-pool Shared_LAS_Pool_C
