HH3C-BFD-STD-MIB
About this MIB
Upper layer protocols implement fast fault detection through the link layer. The fault detection time varies by link type, and failures might not be detected sometimes. POS has the fastest detection speed of approximately 50 milliseconds, which is used to measure fault detection time for other protocols.
BFD provides a general-purpose, standard, medium- and protocol-independent fast failure detection mechanism. BFD can uniformly and quickly detect the failures of the bidirectional forwarding paths between two devices for upper-layer protocols such as routing protocols and MPLS. BFD can provide detection measured in milliseconds, which is close to the detection time implemented by POS.
This document describes the following variables required to implement BFD:
· hh3cBfdGlobalObjects includes hh3cBfdVersionNumber (version number), hh3cBfdSysInitMode (session initialization mode), hh3cBfdSessNotificationsEnable (SNMP notifications switch), and hh3cBfdSessNumberLimit (session limit).
· hh3cBfdIfTable describes BFD interface information.
· hh3cBfdSessTable describes BFD session information.
· hh3cBfdSessStatTable describes BFD session statistics information.
· hh3cBfdSessPerfTable describes BFD session performance information.
· In hh3cBfdNotifications, hh3cBfdSessStateChange describes session state changes (from up to another state, or from another state to up), and hh3cBfdSessAuthFail describes authentication failure information.
HH3C-BFD-STD-MIB is based on draft-ietf-bfd-base-04.txt. This MIB is used for network management protocols in the Internet communities. It describes the objects used to configure or monitor bidirectional forwarding on devices supporting BFD.

Warning |
N/A |
ON |
Notification triggers
This notification is generated when the BFD session changes from Up to another state, or changes to Up from another state.
The BFD session changes from Up to another state for one of the following reasons:
· The path detected by BFD fails, and BFD packets cannot be correctly exchanged as a result.
· The interface bound to the BFD session goes down.
· Other BFD sessions bound to the session go down.
· The BFD session on the remote end is shut down or deleted.
The BFD session changes to Up from another state for one of the following reasons:
· The BFD session changes to Up from Down when it is established or recovers from failures.
· The BFD session changes to Up from Init when it is established or recovers from failures.
· The BFD session changes to Up from AdminDown when its configuration changes.
The BFD session changes to AdminDown from another state when it is deleted.
System impact
If the BFD session changes to Down from another state, the session is abnormal, and the upper-layer application will be affected.
If the BFD session changes to Up from another state, the session recovers, and the upper-layer application will also recover.
The following state changes of the BFD session have no impact on services:
· Down from Init.
· Init from Down.
· AdminDown from Down/Init/Up.
Enabling the notifications will greatly consume CPU resources if a large number of BFD sessions have state changes.

CLI: Use the snmp-agent trap enable bfd command.

Recommended action
To resolve this issue:
1. Identify whether the BFD session changes to Down from another state.
¡ If yes, proceed to step 2.
¡ If no, no action is required.
2. Use the display interface interface-type interface-number command to identify whether the interface bound to the session in Up state.
¡ If yes, proceed to step 3.
¡ If no, connect the physical link correctly and use the display bfd session command to view the session state. If the value for the State field is not Up, proceed to step 3.
3. Use the display bfd session command to identify whether the BFD sessions on the two ends are deleted.
¡ If yes, configure the session on the two ends correctly and use the display bfd session command to view the session state. If the value for the State field is not Up, proceed to step 4.
¡ If no, proceed to step 4.
4. Use the ping command to identify whether the forwarding path can forward packets correctly.
¡ If yes, proceed to step 5.
¡ If no, re-deploy the forwarding path and use the display bfd session command to view the session state. If the value for the State field is not Up, proceed to step 5.
5. If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.

Notification triggers
This notification is generated when the BFD session authentication fails.
Possible reasons for this notification include:
· Authentication settings are configured on only one end of the BFD session.
· Authentication settings are inconsistent on two ends of the BFD session.
· The link between the two ends is faulty.
System impact
The BFD session cannot come up and the upper-layer application will be affected.

Notification triggers
This notification is generated when the BFD session comes up.
Possible reasons for this notification include:
· The BFD session changes to Up from Down when it is established or recovers from failures.
· The BFD session changes to Up from Init when it is established or recovers from failures.
· The BFD session changes to Up from AdminDown when its configuration changes.
System impact
When the BFD session comes up, the associated services will recover.
Enabling the notifications will greatly consume CPU resources if a large number of BFD sessions come up.
Status control
ON
CLI: Use the snmp-agent trap enable bfd command.
OFF
CLI: Use the undo snmp-agent trap enable bfd command.

Notification triggers
This notification is generated when the BFD session goes down.
Possible reasons for this notification include:
· The path detected by BFD fails, and BFD packets cannot be correctly exchanged as a result.
· The interface bound to the BFD session goes down.
· Other BFD sessions bound to the session go down.
· The BFD session on the remote end is shut down or deleted.
System impact
The BFD session state is abnormal, and the upper-layer application will be affected.
Status control
ON
CLI: Use the snmp-agent trap enable bfd command.
OFF
CLI: Use the undo snmp-agent trap enable bfd command.

Recommended action
To resolve this issue:
1. Use the display interface interface-type interface-number command to identify whether the interface bound to the session is in Up state.
¡ If yes, proceed to step 2.
¡ If no, connect the physical link correctly and identify whether the hh3cBfdSessStateUp notification is generated. If the notification is not generated, proceed to step 2.
2. Use the display bfd session command to identify whether the BFD sessions on the two ends are deleted or shutdown.
¡ If the value for the State field is AdminDown, the session has been deleted or shut down. Reconfigure the session on the two ends correctly and identify whether the hh3cBfdSessStateUp notification is generated. If the notification is not generated, proceed to step 3.
¡ If the value for the State field is Down, proceed to step 3.
3. Use the ping command to identify whether the forwarding path can forward packets correctly.
¡ If yes, re-deploy the forwarding path and identify whether the hh3cBfdSessStateUp notification is generated. If the notification is not generated, proceed to step 4.
¡ If no, proceed to step 4.
4. If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.

N/A |
ON |
Notification triggers
This notification is generated when the number of BFD sessions has reached the upper limit on the device.
Possible reasons for this notification include:
· You have created new BFD sessions after the number of BFD sessions reached the upper limit.
· The number of dynamic BFD sessions has exceeded the upper limit.
System impact
You cannot create new BFD sessions after the number of BFD sessions has reached the upper limit on the device.
As a best practice, do not perform the power cycling or reset operation for the device that generates the notification. The operation will result in resource reallocation that affects services.
Status control
ON
CLI: Use the snmp-agent trap enable bfd command.
OFF
CLI: Use the undo snmp-agent trap enable bfd command.

Recommended action
To resolve the issue:
1. Stop creating new BFD sessions.
2. Delete unnecessary BFD sessions. For example, use the undo ospf bfd enable command to delete unnecessary BFD sessions associated with OSPF. For the methods of deleting BFD sessions associated with other features, see the corresponding command references.
3. If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.
