EXTREME-IETF-BFD-MIB: View SNMP OID List / Download MIB

This notification is generated when the extremeBfdSessState object for one or more contiguous entries in extremeBfdSessTable are about to enter the up(4) state from some other state. The included values of extremeBfdSessDiag MUST both be set equal to this new state (i.e: up(4)). The two instances of extremeBfdSessDiag in this notification indicate the range of indexes that are affected. Note that all the indexes of the two ends of the range can be derived from the instance identifiers of these two objects. For the cases where a contiguous range of sessions have transitioned into the up(4) state at roughly the same time, the device SHOULD issue a single notification for each range of contiguous indexes in an effort to minimize the emission of a large number of notifications. If a notification has to be issued for just a single extremeBfdSessEntry, then the instance identifier (and values) of the two extremeBfdSessDiag objects MUST be the identical.

This notification is generated when the extremeBfdSessState object for one or more contiguous entries in extremeBfdSessTable are about to enter the down(2) or adminDown(1) states from some other state. The included values of extremeBfdSessDiag MUST both be set equal to this new state (i.e: down(2) or adminDown(1)). The two instances of extremeBfdSessDiag in this notification indicate the range of indexes that are affected. Note that all the indexes of the two ends of the range can be derived from the instance identifiers of these two objects. For cases where a contiguous range of sessions have transitioned into the down(2) or adminDown(1) states at roughly the same time, the device SHOULD issue a single notification for each range of contiguous indexes in an effort to minimize the emission of a large number of notifications. If a notification has to be issued for just a single extremeBfdSessEntry, then the instance identifier (and values) of the two extremeBfdSessDiag objects MUST be the identical.

The global administrative status of BFD in this device. The value enabled denotes that the BFD Process is active on at least one interface; disabled disables it on all interfaces.

If this object is set to true(1), then it enables the emission of extremeBfdSessUp and extremeBfdSessDown notifications; otherwise these notifications are not emitted.

The BFD Session Table describes the BFD sessions.

The BFD Session Entry describes BFD session.

This object contains an index used to represent a unique BFD session on this device.

The version number of the BFD protocol that this session is running in. Write access is available for this object to provide ability to set desired version for this BFD session.

This object specifies the type of this BFD session.

This object specifies the local discriminator for this BFD session, used to uniquely identify it.

This object specifies the session discriminator chosen by the remote system for this BFD session. The value may be zero(0) if the remote discriminator is not yet known or if the session is in the down or adminDown(1) state.

This object specifies the destination UDP port number used for this BFD sessions control packets. The value may be zero(0) if the session is in adminDown(1) state.

This object specifies the source UDP port number used for this BFD sessions control packets. The value may be zero(0) if the session is in adminDown(1) state. Upon creation of a new BFD session via this MIB, the value of zero(0) specified would permit the implementation to chose its own source port number.

This object specifies the source UDP port number used for this BFD sessions echo packets. The value may be zero(0) if the session is not running in the echo mode, or the session is in adminDown(1) state. Upon creation of a new BFD session via this MIB, the value of zero(0) would permit the implementation to chose its own source port number.

A transition from stop to start will start the BFD state machine for the session. The state machine will have an initial state of down. A transition from start to stop will cause the BFD sesssion to be brought down to adminDown(1). Care should be used in providing write access to this object without adequate authentication.

BFD session state.

This object specifies status of BFD packet reception from the remote system. Specifically, it is set to true(1) if the local system is actively receiving BFD packets from the remote system, and is set to false(2) if the local system has not received BFD packets recently (within the detection time) or if the local system is attempting to tear down the BFD session.

A diagnostic code specifying the local systems reason for the last transition of the session from up(4) to some other state.

This object specifies current operating mode that BFD session is operating in.

This object indicates that the local systems desire to use Demand mode. Specifically, it is set to true(1) if the local system wishes to use Demand mode or false(2) if not

This object indicates that the local systems ability to continue to function through a disruption of the control plane. Specifically, it is set to true(1) if the local system BFD implementation is independent of the control plane. Otherwise, the value is set to false(2)

This object indicates the Multipoint (M) bit for this session. It is set to true(1) if Multipoint (M) bit is set to 1. Otherwise, the value is set to false(2)

This object contains an interface index used to indicate the interface which this BFD session is running on. This value can be zero if there is no interface associated with this BFD session.

This object specifies IP address type of the source IP address of this BFD session. Only values unknown(0), ipv4(1), ipv6(2), or ipv6z(4) have to be supported. The value of unknown(0) is allowed only when the session is singleHop(1) and the source IP address of this BFD session is drived from the outgoing interface, or when the BFD session is not associated with a specific interface. If any other unsupported values are attempted in a set operation, the agent MUST return an inconsistentValue error.

This object specifies the source IP address of this BFD session.

This object specifies IP address type of the neighboring IP address which is being monitored with this BFD session. Only values unknown(0), ipv4(1), ipv6(2), or ipv6z(4) have to be supported. The value of unknown(0) is allowed only when the session is singleHop(1) and the outgoing interface is of type point-to-point, or when the BFD session is not associated with a specific interface. If any other unsupported values are attempted in a set operation, the agent MUST return an inconsistentValue error.

This object specifies the neighboring IP address which is being monitored with this BFD session.

Setting the value of this object to true(1) will enable GTSM protection of the BFD session. GTSM MUST be enabled on a singleHop(1) session if no authentication is in use.

This object is valid only when extremeBfdSessGTSM protection is enabled on the system. This object specifies the minimum allowed TTL for received BFD control packets. For singleHop(1) session, if GTSM protection is enabled, this object SHOULD be set to maximum TTL allowed for single hop. The value of zero(0) indicates that extremeBfdSessGTSM is disabled.

This object specifies the minimum interval, in microseconds, that the local system would like to use when transmitting BFD Control packets. The value of zero(0) is reserved, and should not be used.

This object specifies the minimum interval, in microseconds, between received BFD Control packets the local system is capable of supporting. The value of zero(0) can be specified when the transmitting system does not want the remote system to send any periodic BFD control packets.

This object specifies the minimum interval, in microseconds, between received BFD Echo packets that this system is capable of supporting. Value must be zero(0) if this is a multihop BFD session.

This object specifies the Detect time multiplier.

This object specifies the negotiated interval, in microseconds, that the local system is transmitting BFD Control packets.

This object specifies the negotiated interval, in microseconds, that the local system is transmitting BFD echo packets. Value is expected to be zero if the sessions is not running in echo mode.

This object specifies the Detect time multiplier.

This object indicates that the local systems desire to use Authentication. Specifically, it is set to true(1) if the local system wishes the session to be authenticated or false(2) if not.

The Authentication Type used for this BFD session. This field is valid only when the Authentication Present bit is set. Max-access to this object as well as other authentication related objects are set to read-create in order to support management of a single key ID at a time, key rotation is not handled. Key update in practice must be done by atomic update using a set containing all affected objects in the same varBindList or otherwise risk the session dropping. Value -1 indicates that no authentication is in use for this session.

The authentication key ID in use for this session. This object permits multiple keys to be active simultaneously. When extremeBfdSessAuthPresFlag is false(2), then the value of this object MUST be -1. The value -1 indicates that no Authentication Key ID will be present in the optional BFD Authentication Section.

The authentication key. When the extremeBfdSessAuthenticationType is simplePassword(1), the value of this object is the password present in the BFD packets. When the extremeBfdSessAuthentication type is one of the keyed authentication types, this value is used in the computation of the key present in the BFD authentication packet.

This variable indicates the storage type for this object. Conceptual rows having the value permanent need not allow write-access to any columnar objects in the row.

This variable is used to create, modify, and/or delete a row in this table. When a row in this table has a row in the active(1) state, no objects in this row can be modified except the extremeBfdSessRowStatus and extremeBfdSessStorageType.

This table specifies BFD Session performance counters.
