"This MIB module defines configuration objects for managing
IPsec Security Policies. In general, this MIB can be
implemented anywhere IPsec security services exist (e.g.,
bump-in-the-wire, host, gateway, firewall, router, etc.).
Copyright (C) The IETF Trust (2007). This version of
this MIB module is part of RFC 4807; see the RFC itself for

SpdBooleanOperator ::= TEXTUAL-CONVENTION

DESCRIPTION
"The SpdBooleanOperator operator is used to specify
whether sub-components in a decision-making process are
ANDed or ORed together to decide if the resulting
expression is true or false."
SYNTAX INTEGER { or(1), and(2) }
SpdAdminStatus ::= TEXTUAL-CONVENTION

SpdIPPacketLogging ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"SpdIPPacketLogging specifies whether an audit message
SHOULD be logged if a packet is passed through a Security
Association (SA) and if some of that packet is included in
the log event. A value of '-1' indicates no logging. A
value of '0' or greater indicates that logging SHOULD be
done and indicates the number of bytes starting at the
beginning of the packet to place in the log. Values greater
than the size of the packet being processed indicate that
the entire packet SHOULD be sent.
Examples:
'-1' no logging
'0' log but do not include any of the packet in the log
'20' log and include the first 20 bytes of the packet
in the log."
SYNTAX Integer32 (-1..65535)
SpdTimePeriod ::= TEXTUAL-CONVENTION
DISPLAY-HINT "31t"
STATUS current
DESCRIPTION
"This property identifies an overall range of calendar dates
and time. In a boolean context, a value within this time
range, inclusive, is considered true.
This information is encoded as an octet string using
the UTF-8 transformation format described in STD 63,
RFC 3629.
It uses the format suggested in RFC 3060. An octet string
represents a start date and time and an end date and time.
For example:
yyyymmddThhmmss/yyyymmddThhmmss
Where: yyyy = year mm = month dd = day
hh = hour mm = minute ss = second
The first 'yyyymmddThhmmss' sub-string indicates the start
date and time. The second 'yyyymmddThhmmss' sub-string
indicates the end date and time. The character 'T' within
these sub-strings indicates the beginning of the time
portion of each sub-string. The solidus character '/'
separates the start from the end date and time. The end
date and time MUST be subsequent to the start date and
time.
There are also two allowed substitutes for a
'yyyymmddThhmmss' sub-string: one for the start date and
time, and one for the end date and time.
If the start date and time are replaced with the string
'THISANDPRIOR', this sub-string would indicate the current
date and time and the previous dates and time.
If the end date and time are replaced with the string
'THISANDFUTURE', this sub-string would indicate the current
date and time and the subsequent dates and time.
Any of the following SHOULD be considered a
'wrongValue' error:
- Setting a value with the end date and time earlier than
or equal to the start date and time.
- Setting the start date and time to 'THISANDFUTURE'.
- Setting the end date and time to 'THISANDPRIOR'."

spdGroupContFilter OBJECT-TYPE
SYNTAX VariablePointer
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"spdGroupContFilter points to a filter that is evaluated
to determine whether the spdGroupContComponentName within
this row is exercised. Managers can use this object to
classify groups of rules, or subgroups, together in order to
achieve a greater degree of control and optimization over
the execution order of the items within the group. If the
filter evaluates to false, the rule or subgroup will be
skipped and the next rule or subgroup will be evaluated
instead. This value can be used to indicate a scalar or
row in a table. When indicating a row in a table, this
value MUST point to the first column instance in that row.
An example usage of this object would be to limit a
group of rules to executing only when the IP packet
being processed is designated to be processed by IKE.
This effectively creates a group of IKE-specific rules.
The following tables and scalars can be pointed to by this
column. All but diffServMultiFieldClfrTable are defined in
this MIB:
diffServMultiFieldClfrTable
spdIpOffsetFilterTable
spdTimeFilterTable

Implementations MAY choose to provide support for other
filter tables or scalars.
If this column is set to a VariablePointer value, which
references a non-existent row in an otherwise supported
table, the inconsistentName exception MUST be returned. If
the table or scalar pointed to by the VariablePointer is
not supported at all, then an inconsistentValue exception
MUST be returned.
If, during packet processing, a row in this table is applied
to a packet and the value of this column in that row
references a non-existent or non-supported object, the
packet MUST be dropped."

DESCRIPTION
"This defines the various tests that are used when

The various tests definable in this table are as follows:
equal:
- Tests if the OCTET STRING, 'spdIpOffFiltValue', matches
a value in the packet starting at the given offset in
the packet and comparing the entire OCTET STRING of
'spdIpOffFiltValue'. Any values compared this way are
assumed to be unsigned integer values in network byte
order of the same length as 'spdIpOffFiltValue'.
notEqual:
- Tests if the OCTET STRING, 'spdIpOffFiltValue', does
not match a value in the packet starting at the given
offset in the packet and comparing to the entire OCTET
STRING of 'spdIpOffFiltValue'. Any values compared
this way are assumed to be unsigned integer values in
network byte order of the same length as
'spdIpOffFiltValue'.
arithmeticLess:
- Tests if the OCTET STRING, 'spdIpOffFiltValue', is
arithmetically less than ('<') the value starting at
the given offset within the packet. The value in the
packet is assumed to be an unsigned integer in network
byte order of the same length as 'spdIpOffFiltValue'.
arithmeticGreaterOrEqual:
- Tests if the OCTET STRING, 'spdIpOffFiltValue', is
arithmetically greater than or equal to ('>=') the
value starting at the given offset within the packet.
The value in the packet is assumed to be an unsigned
integer in network byte order of the same length as
'spdIpOffFiltValue'.
arithmeticGreater:
- Tests if the OCTET STRING, 'spdIpOffFiltValue', is
arithmetically greater than ('>') the value starting at
the given offset within the packet. The value in the
packet is assumed to be an unsigned integer in network
byte order of the same length as 'spdIpOffFiltValue'.
arithmeticLessOrEqual:
- Tests if the OCTET STRING, 'spdIpOffFiltValue', is
arithmetically less than or equal to ('<=') the value
starting at the given offset within the packet. The
value in the packet is assumed to be an unsigned
integer in network byte order of the same length as

DESCRIPTION
"Defines which days of the month the current time is
valid for. It is a sequence of 64 BITS, where each BIT
represents a corresponding day of the month in forward or
reverse order. Starting from the left-most bit, the first
31 bits identify the day of the month, counting from the
beginning of the month. The following 31 bits (bits 32-62)
indicate the day of the month, counting from the end of the
month. For months with fewer than 31 days, the bits that
correspond to the non-existent days of that month are
ignored (e.g., for non-leap year Februarys, bits 29-31 and
60-62 are ignored).
This column evaluates to 'true' if the current day of the
month's bit is set.
For example, a value of 0X'80 00 00 01 00 00 00 00'
indicates that this column evaluates to true on the first
and last days of the month.
The last two bits in the string MUST be zero."
