This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects for the General Switch
Management Protocol (GSMP).
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
The SNMP Management Framework presently consists of five major
components:
* An overall architecture, described in RFC 2571 [RFC2571].
* Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and is described in
STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212], and RFC
1215 [RFC1215]. The second version, called SMIv2, is described in
STD 58, RFC 2578 [RFC2578], RFC 2579 [RFC2579], and RFC
2580[RFC2580].
* Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and is
described in STD 15, RFC 1157 [RFC1157]. A second version of the
SNMP message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and is described in RFC 1901 [RFC1901]
and RFC 1906 [RFC1906]. The third version of the message protocol
is called SNMPv3 and is described in RFC 1906 [RFC1906], RFC 2572
[RFC2572], and RFC 2574 [RFC2574].
* Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats are
described in STD 15, RFC 1157 [RFC1157]. A second set of
operations and associated PDU formats are described in 1905
[RFC1905].
Sjostrand, et. al. Standards Track [Page 2]
RFC 3295 GSMP MIB June 2002
* A set of fundamental applications described in RFC 2573 [RFC2573],
and the view-based access control mechanism is described in RFC
2575 [RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
This memo defines a portion of the Management Information Base (MIB)
for the use with network management protocols in the Internet
community. In particular, it describes managed objects for the
General Switch Management Protocol (GSMP), as defined in [RFC3292].
The General Switch Management Protocol (GSMP) is a general purpose
protocol to control a label switch. GSMP allows a controller to
establish and release connections across the switch, to manage switch
ports and to request configuration information or statistics. It
also allows the switch to inform the controller of asynchronous
events such as a link going down.
The GSMP protocol is asymmetric, the controller being the master and
the switch being the slave. Multiple switches may be controlled by a
single controller using multiple instantiations of the protocol over
separate control connections. Also a switch may be controlled by
more than one controller by using the technique of partitioning.
Each instance of a (switch controller, switch partition) adjacency is
a session between one switch controller entity and one switch entity.
The MIB provides objects to configure/setup these entities to form
the GSMP sessions. It also provide objects to monitor these GSMP
sessions.
Sjostrand, et. al. Standards Track [Page 3]
RFC 3295 GSMP MIB June 2002
The GSMP mib is a protocol mib. It contains objects to configure,
monitor, and maintain the GSMP protocol entity. It does not provide
any information learned via the protocol, such as "all ports config"
information.
The relationships between virtual entities, such as Virtual Switch
Entities, and "physical" entities, such as Switch Entities, falls
outside of the management of GSMP. This also applies for the
management of switch partitions. So this is excluded from the GSMP
mib.
It is possible to configure which, and how many Switch Controllers
are controlling one Switch since every potential session with the
switch has to be represented with an Switch entity. It is, however,
not possible to define that one Switch Controller shouldn't allow
other Switch controllers to control the same switch or partition on
the switch. It is assumed that there are mechanisms that synchronise
controllers and the configuration of them. This is outside the scope
of this mib.
Two tables are used to configure potential GSMP sessions depending if
you are acting as a GSMP switch controller or a GSMP switch. Each
row in these tables initiates a GSMP session.
The entity ID is a 48-bit name that is unique within the operational
context of the device. A 48-bit IEEE 802 MAC address, if available,
MAY be used for the entity ID. If the Ethernet encapsulation is
used, the entity ID MUST be the IEEE 802 MAC address of the interface
on which the GSMP session is to be setup.
First, the encapsulation of the potential GSMP session shall be
defined. If ATM is used, a row in the gsmpAtmEncapTable has to be
created with the index set to the entity ID. The specified resources
should be allocated to GSMP. If TCP/IP is used, a row in the
gsmpTcpIpEncapTable has to be created with the index set to the
entity ID. The specified port shall be allocated to GSMP. No
special action is needed if ethernet encapsulation is used.
Then the entity information shall be defined. To create a Switch
Entity, an entry in the gsmpSwitchTable is created with the index set
to the entity ID. To create a Switch Controller Entity, an entry in
the gsmpControllerTable is created with the index set to the entity
ID.
Sjostrand, et. al. Standards Track [Page 4]
RFC 3295 GSMP MIB June 2002
When the row status of the GsmpControllerEntry or GsmpSwitchEntry is
set to active (e.g., in the case with ATM or TCP/IP there are active
rows with a corresponding entity ID), the adjacency protocol of GSMP
is started.
Another table, the gsmpSessionTable, shows the actual sessions that
are established or are in the process of being established. Each row
represents a specific session between an Entity and a peer. This
table carries information about the peer, the session, and parameters
that were negotiated by the adjacency procedures. The
gsmpSessionTable also contains statistical information regarding the
session.
This creation order SHOULD be used by all GSMP managers. This is to
avoid clash situations in multiple SNMP manager scenarios where
different managers may create competing entries in the different
tables.
Entities may very well be configured by other means than SNMP, e.g.,
the cli command. Such configured entities SHOULD be represented as
entries in the tables of this mib and SHOULD be possible to query,
and MAY be possible to alter with SNMP.
The controller group is used to configure a potential GSMP session on
a Switch Controller. A row in the gsmpControllerTable is created for
each such session. If ATM or TCP/IP encapsulation is used, a
corresponding row has to be created in these tables before the
session adjacency protocol is initiated.
If ATM or TCP/IP is used, encapsulation data is defined in the
corresponding encapsulation tables. If ethernet is used, the MAC
address of the interface defined for the session is set by the
Controller ID object.
The adjacency parameters are defined; such as
- Max supported GSMP version.
- Time between the periodic adjacency messages.
- Controller local port number and instance number.
- Whether partitions are being used and the partition ID for the
specific partitions this controller is concerned with if
partitions are used.
- The resynchronisation strategy for the session is specified.
Sjostrand, et. al. Standards Track [Page 5]
RFC 3295 GSMP MIB June 2002
The notification mapping is set to specify for with events the
corresponding SNMP notifications are sent.
The switch group is used to configure a potential GSMP session on a
Switch. A row in the gsmpSwitchTable is created for each such
session. If ATM or TCP/IP encapsulation is used, a corresponding row
has to be created in these tables before the session adjacency
protocol is initiated.
If ATM or TCP/IP is used, encapsulation data is defined in the
corresponding encapsulation tables. If ethernet is used the MAC
address of the interface defined for the session is set by the Switch
ID object.
The adjacency parameters are defined; such as
- Max supported GSMP version
- Time between the periodic adjacency messages
- Switch Name, local port number, and instance number.
- Whether partitions are being used and the partition ID for this
specific partition if partitions are used.
- The switch type could be set.
- The suggested maximum window size for unacknowledged request
messages.
Also, a notification mapping is set to specify for with events the
corresponding SNMP notifications are sent.
The ATM Encapsulation Table and the TCP/IP Encapsulation Table
provides a way to configure information that are encapsulation
specific. The encapsulation data is further specified in [RFC3293].
If ATM encapsulation is used, the interface and the virtual channel
are specified.
If TCP/IP is used, the IP address and the port number are specified.
No special config data needed if Ethernet encapsulation is used.
This mib MAY be extended with new, standard or proprietary, GSMP
encapsulation types. If a new encapsulation type needs to be added,
it SHOULD be done in the form of a new table with the entity ID as an
index. A row in that encapsulation table SHOULD be created before
any row in a GSMP entity table is created that is using this new GSMP
encapsulation.
Sjostrand, et. al. Standards Track [Page 6]
RFC 3295 GSMP MIB June 2002
The GSMP session table provides a way to monitor and maintain GSMP
sessions.
The session is defined by a Switch Controller Entity and Switch
Entity pair.
The GSMP Notification Group defines notifications for GSMP entities.
These notifications provide a mechanism for a GSMP device to inform
the management station of status changes. Also a notification is
defined for each type of GSMP events.
The group of notifications consists of the following notifications:
- gsmpSessionDown
This notification is generated when a session is terminating and also
reports the final accounting statistics of the session.
- gsmpSessionUp
This notification is generated when a new session is established.
- gsmpSendFailureInd
This notification is generated when a message with a failure
indication was sent. This means that this notification identifies a
change to the gsmpSessionStatFailureInds object in a row of the
gsmpSessionTable.
- gsmpReceivedFailureInd
This notification is generated when a message with a failure
indication received. This means that this notification identifies a
change to the gsmpSessionStatReceivedFailures object in a row of the
gsmpSessionTable.
- gsmpPortUpEvent
This notification is generated when a Port Up Event is either
received or sent.
Sjostrand, et. al. Standards Track [Page 7]
RFC 3295 GSMP MIB June 2002
- gsmpPortDownEvent
This notification is generated when a Port Down Event is either
received or sent.
- gsmpInvalidLabelEvent
This notification is generated when an Invalid Label Event is either
received or sent.
- gsmpNewPortEvent
This notification is generated when New Port Event either is received
or sent.
- gsmpDeadPortEvent
This notification is generated when a Dead Port Event is either
received or sent.
- gsmpAdjacencyUpdateEvent
This notification is generated when an Adjacency Update Event is
either received or sent.
To disable or enable the sending of each notification, the bits in
the bitmap are set to 0 or 1 in the Notification mapping objects in
the Controller Entitiy or Switch Entity tables.
The GSMP notification map capability should not be seen as a
duplication of the filter mechanism in the snmp notification
originator application [RFC2573], but as a compliment, to configure
the relation between GSMP events and the SNMP notifications already
in the GSMP agent. SNMP notifications and GSMP events operate
sometimes on a different timescale, and it may in some applications
be devastating for a SNMP application to receive events for each GSMP
events. E.g. the invalid label event in a ATM switch scenario may
cause mass SNMP notification flooding if mapped to a SNMP
notification.
The datatypes GsmpNameType, GsmpLabelType, GsmpVersion,
GsmpPartitionType, and GsmpPartitionIdType are used as textual
conventions in this document. These textual conventions are used for
the convenience of humans reading the MIB. Objects defined using
these conventions are always encoded by means of the rules that
define their primitive type. However, the textual conventions have
Sjostrand, et. al. Standards Track [Page 8]
RFC 3295 GSMP MIB June 2002
special semantics associated with them. Hence, no changes to the SMI
or the SNMP are necessary to accommodate these textual conventions
which are adopted merely for the convenience of readers.

RFC 3295 GSMP MIB June 2002
Assuming that secure network management (such as SNMP v3) is
implemented, the objects represented in this MIB do not pose a threat
to the security of the network.
There are a number of management objects defined in this MIB that
have a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations.
There are a number of managed objects in this MIB that may contain
sensitive information. They are contained in the gsmpControllerTable
and gsmpSwitchTable. It is thus important to control even GET access
to these objects and possibly to even encrypt the values of these
object when sending them over the network via SNMP. Not all versions
of SNMP provide features for such a secure environment.
SNMPv1 by itself is not a secure environment. Even if the network
itself is secure (for example by using IPSec), even then, there is no
control as to who on the secure network is allowed to access and
GET/SET (read/change/create/delete) the objects in this MIB.
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model RFC 2574 [RFC2574] and the View-
based Access Control Model RFC 2575 [RFC2575] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects, only to those principals
(users) that have legitimate rights to indeed GET or SET
(change/create/delete) them.
