Clearing an IP DHCP Local Server Binding
NOTE:
This command is deprecated and might be removed completely in a future
release. The function provided by this command has been replaced by the
dhcp
delete-binding
command.
You can use the
clear ip dhcp-local binding
command to force the removal of a
connected user's IP address lease and associated route configuration. Using this
command enables you to:
■
Recover functional resources from a user who has not explicitly terminated
connectivity and whose lease is unexpired.
■
Discontinue connectivity to a user, prompting or forcing the user to request a
new lease in order to reestablish network connectivity.
Using SNMP Traps to Monitor DHCP Local Server Events
The DHCP local server supports configurable global SNMP traps that monitor events
related to the DHCP local server and local SNMP traps that are related to address
pool utilization.You use the
ip dhcp-local snmpTraps
command to enable the global
SNMP traps for DHCP local server.
The DHCP local server’s global SNMP trap generates severity level 1 (alert), 2 (critical),
and 3 (error) events. This trap helps administrators monitor DHCP local server general
health, error statistics, address lease status, and protocol events. The global SNMP
trap generates a severity level 4 (warning) event when a duplicate MAC address is
detected. The global SNMP trap information is captured in the dhcpLocalGeneral
logging category.
SNMP also traps events related to address pool utilization. You use the
warning
command to define the maximum and minimum threshold values and the
snmpTrap
command to generate traps when utilization occurs above or below the defined
values.
For linked or shared pools, SNMP treats the members of the pool as a group, and
uses the values configured for the first pool in the chain as the group’s threshold.
The address pool utilization SNMP trap information is captured in the dhcpLocalPool
logging category.
NOTE:
You must configure your SNMP management client to read the MIB objects,
and your SNMP trap collector must be capable of decoding the new traps. For
information about setting up SNMP, see the
Configuring SNMP
