The oper-participation of $tmnxIsisFlexAlgoId$ in level $tmnxIsisNotifSystemLevel$ is operationally down due to $tmnxIsisNotifyDescription$.

Cause

The tmnxIsisFaOperParticipationDown notification is sent when the Flexible Algorithm Participation is operationally down. This notification occurs each time when: a) there are no Flexible Algorithm Definitions(FADs) present for the Flexible Algorithm. b) the FAD chosen for Flex-Algo calculation has unsupported parameters like unsupported: 1. Metric-Type 2. Calculation-Type 3. Constraint 4. Fad-Flags 5. Sub-Tlv

Effect

The node will cease to participate in that Flexible Algorithm, and won't advertise its participation in SR-algo sub-TLV.

Recovery

The operator may make sure if at least one FAD is present for that Flexible Algorithm, and in case of unsupported FAD, correct the FAD parameters to send supported values from remote side.

Message format string

Protocol disabled due to attempt to exceed the maximum sequence on level: $tmnxIsisNotifSystemLevel$, with LSP-id: $vRtrIsisTrapLSPIDString$. Shutdown for a while and start over.

Cause

The tmnxIsisMaxSeqExceedAttempt notification is generated when the sequence number on an LSP wraps the 32 bit sequence counter, we purge and wait to re-announce this information. Since these should not be generated rapidly, we generate an event each time this happens. A possible cause could be that the same system-id is configured on multiple nodes; when 2 nodes have the same system-id they both keep incrementing its LSP sequence number causing the sequence counter to rollover. While the first 6 bytes of the LSPID are ours, the other two contain useful information.

Cause

The tmnxIsisOrigLSPBufSizeMismatch notification is sent when a Level 1 LSP or Level 2 LSP is received which is larger than the local value for isisSysOrigL1LSPBuffSize or isisSysOrigL2LSPBuffSize respectively, or when a Level 1 LSP or Level2 LSP is received containing the originatingLSPBufferSize option and the value in the PDU option field does not match the local value for isisSysOrigL1LSPBuffSize or isisSysOrigL2LSPBuffSize respectively. We pass up the size from the option field or the size of the LSP that exceeds our configuration. This should be an edge-triggered notification.

The tmnxIsisRejectedEndXSid notification is sent when we do not establish a SRv6 End-X SID due to a lack of resources. This should be an edge-triggered notification. We should not send a second notification about end-x SID allocation failure for the same adjacency.

Effect

No effect.

Recovery

Whenever an end-x SID is released, the released end-x SID can be reused by any other adjacency which is waiting to receive an end-x SID.

Cause

This notification is generated when ISIS receives an IOM or CPM failure (system exhausted ILM, NHLFE, duplicate SID) while resolving and programming a received prefix SID.

Effect

The Segment Routing tunnel corresponding to this SID will not be programmed.

Recovery

In case of system exhaustion, the IGP instance goes into overload. The operator must manually clear the IGP overload condition after freeing resources. IGP will attempt to program at the next SPF all tunnels which previously failed the programming operation

warning

Message format string

Possible messages:

  • Statistics Index Allocation status changed to $tmnxIsisNotifStatsIndexStatus$ for adjacency-set $tmnxIsisSidStatsAdjSet$

  • Statistics Index Allocation status changed to $tmnxIsisNotifStatsIndexStatus$ for adjacency interface $tmnxIsisSidStatsIfIndex$

  • Statistics Index Allocation status changed to $tmnxIsisNotifStatsIndexStatus$ for node $tmnxIsisSidStatsPrefix$/$tmnxIsisSidStatsPrefixLength$

Cause

The tmnxIsisSidStatsIndexAlloc notification is sent when the system is not able to allocate a statistic index to at least one SID. This indication is sent once, i.e. if the system retries to allocate a stat index but fails no new notification is sent. Conversely, in case the system resolves the situation and allocates stat indices to all needed SIDs a notification is sent to indicate that stat allocation is in nominal state.

Effect

No effect.

Cause

The tmnxIsisSrgbBadLabelRange notification is sent when ISIS receives a bad SRGB label range from a router (for example, overlapping with another label range).

Effect

The configured Segment Routing tunnels will be wrong.

Recovery

Change the label range to recover.

Message format string

Protocol version skew - $tmnxIsisNotifProtocolVersion$ on interface: $vRtrIfIndex$, for level: $tmnxIsisNotifSystemLevel$, fragment: $vRtrIsisPDUFragmentString$

Cause

The tmnxIsisVersionSkew notification is sent when we receive a Hello PDU from an IS running a different version of the protocol. This notification includes the header of the packet, which may help a network manager identify the source of the confusion. This should be an edge-triggered notification. We should not send a second notification about PDUs received from what seem to be the same source. This decision is up to the agent to make, and may be based on the circuit or on some MAC level information.

Effect

No effect.

Recovery

No recovery is necessary.
