Configuration CLI

Use the Command-Line Interface (CLI) to configure the general LEG settings of the DHCP Lease Query LEG.

To enable the LEG:

SCE(config)# subscriber LEG dhcp-lease-query
To disable the LEG:

SCE(config)# no subscriber LEG dhcp-lease-query
To set the IP addresses of the DHCP servers (one or two addresses):

SCE(config)# subscriber LEG dhcp-lease-query servers STRING STRING
To reset the DHCP servers:

SCE(config)# no subscriber LEG dhcp-lease-query servers
To set the session_timeout configuration variable:

SCE(config)# subscriber LEG dhcp-lease-query session-timeout DECIMAL
To set the session_timeout variable to the default value:

SCE(config)# default subscriber LEG dhcp-lease-query session_timeout
The failover criteria configuration variable defines the number of consecutive request failures (timeouts) that triggers a fail-over. Because the queries are not answered when the server fails, these queries time out. The consecutive timed-out queries are counted and when they reach this threshold, the second server is set as the active server. The default value is 3.

To set the fail_over_criteria:

SCE(config)# subscriber LEG dhcp-lease-query failover-criteriaDECIMAL
To set the fail_over_criteria variable to the default value:

SCE(config)# default subscriber LEG dhcp-lease-query failover-criteria
To set subscriber ID option:

SCE(config)# subscriber LEG dhcp-lease-query sub-id-option STRINGbinary|string[ip-fallback]
To set the subscriber ID option to the default value:

SCE(config)# default subscriber LEG dhcp-lease-query sub-id-option
For policy association, the LEG uses exactly the same file described in the Configuring Policy Association section. Set and load the configuration file with the following CLI (you must specify the full path and the file name):

SCE(config)# subscriber LEG dhcp-lease-query package-association-file STRING
The default package association configuration does not assign package information. To set the configuration back to the default configuration file:

SCE(config)# default subscriber LEG dhcp-lease-query package-association-file
To set all parameters of the DHCP lease query LEG to the default settings, use the following CLI:

SCE(config)# default subscriber LEG dhcp-lease-query
Show CLI

To view the general configuration of the LEG, enter the following command:

SCE# show subscriber LEG dhcp-lease-query
To view the statistics counters of the LEG:

SCE# show subscriber LEG dhcp-lease-query counters
To reset the statistics counters of the LEG:

SCE# clear subscriber LEG dhcp-lease-query counters
