The window size of the IPsec Phase-2 History Tables.
The IPsec Phase-2 History Tables are implemented as
a sliding window in which only the last 'N' entries
are maintained. This object is used specify the number
of entries which will be maintained in the IPsec
Phase-2 History Tables.
An implementation may choose suitable minimum and
maximum values for this element based on the local
policy and available resources. If an SNMP SET request
specifies a value outside this window for this element,
in appropriate SNMP error code should be returned.
Setting this value to zero is equivalent to deleting
all conceptual rows in the archiving tables
('ceipSecHistTable' and 'ceipSecEndPtHistTable') and
disabling the archiving of entries in the tables.
