lease-populate
Syntax lease-populate [number-of-entries]
no lease-populate
Context config>service>ies>if>dhcp
config>service>ies>sub-if>grp-if>dhcp
Description This command enables dynamic host lease state management for IES IP interfaces. Lease state
information is extracted from snooped or relayed DHCP ACK messages to populate lease state table
entries for the IP interface.
If lease state population is enabled and an entry cannot be added to the table, the system will prevent
the far-end host from receiving the DHCP ACK message.
The retained lease state information representing dynamic hosts may be used to populate a SAP based
anti-spoof filter table to provide dynamic anti-spoof filtering and/or ARP cache population.
Default ies>if>dhcp: no lease-populate
ies>sub-if>grp-if>dhcp: 1
Parameters number-of-entries — This optional parameter defines the number of lease state table entries allowed
for this IP interface. If number-of-entries is not specified, only a single entry is allowed. Once the
maximum number of entries has been reached, subsequent lease state entries are not allowed.
