Message format string

For peers $tmnxMcPeerIpAddrForNotify$ and $tmnxMcPeerSrcIpAddr$ both nodes locked to the active operational role

Cause

A misconfiguration, to enable mc-master-lock on both Primary and Secondary geo-redundancy nodes is ONLY allowed when mc-mobile link between the geo-redundancy nodes is down and both have turned into the active operational role. When the mc-mobile link comes UP, the notification tmnxMcMobileBothLockedToMaster is generated indicating both the Primary and Secondary nodes are locked in the active operational role. Under steady state, that is, mc-mobile link between the geo-redundancy nodes is UP and peering is successful, mc-master-lock CLI configuration is allowed only on the node in the active operational role.

Effect

The geo-redundancy link will not be established as these mobile-gateways cannot be peered.

Recovery

Diagnose and fix the mc-master-lock misconfiguration.

Cause

The chassis or the CPM changed its geo-redundancy state or the peer connection status changed.

Effect

If the chassis state or the CPM state has changed to "cold" or "warm" the system is no longer in geo-redundant state. If the peer state is "disconnected" the system is no longer in a geo-redundant state.

Recovery

Diagnose what caused this state change. Bring the peer and/or peer-link up and ensure that the chassis and CPM geo-redundancy states are "hot".

Effect

If it is the primary UPF that changed, the traffic associated with this Fate Sharing Group is now going through another UPF system. If it is the secondary UPF that changed and if the pair is hot-standby, another UPF system now keeps track of sessions state.

Gw-$tmnxMobGwNtfyGatewayId$, Ref point- $tmnxMobGwNtfyRefPointType$, RefPointName-$tmnxMobGwNtfyRefPointName$, InterfaceType-$tmnxMobGwNtfyIfType$.

Cause

Traffic is detected at the ICR node due to a network issue.

Effect

When traffic comes to the ICR node, it is dropped if traffic redirection, which means shunting, is not used. If shunting is used, then the traffic is forwarded accordingly.

Recovery

Cause

The set of internal parameters for ICC call latency and memory utilization reach the high threshold (activated), and/or fall below the low threshold for at least some time period (de-activated).

Effect

When the ABS alarm is active, the application will use the Selective Packet Discard flag passed from the Octeon drive to make a decision if the packet should be dropped. When the ABS alarm is inactive, the Octeon drive will stop passing the Selective Packet Discard flag to the application.

Recovery

Cause

Cause

The Association state changes when the association is either setup or released. The association can be setup/released by association related Node level messages triggered by either the gateway or the peer. Association Messages are initiated by the gateway if the peer is configured in the association Peer list.

Effect

Path management for PFCP peers and UPF selection can occur after the association is established. Path management or UPF selection will not happen in case of association down.

Recovery

If the association state is down and the release was initiated by the Gateway, the Gateway must come up for the association to be reestablished. If the release was initiated by the peer, the peer will trigger the setup when it comes up again.

Cause

A tmnxMobGwCntrlFabricPartialFail is generated when a card loses connectivity to other cards in a particular direction over a particular control fabric. The card ID is indicated in tmnxMobGwNtfySlot, the failed fabric ID is indicated in tmnxMobGwNtfyFabricId and the direction of the failure (transmit/receive) is indicated in tmnxMobGwNtfyFailureDirection.

Cause

The SGW starts throttling the DDN when it receives a throttling instruction carried in the "downlink (DL) low priority traffic Throttling" IE from a peer node.

Effect

The SGW starts throttling the DDN based on a priority threshold value. The traffic with a priority value higher than or equal to the threshold value is considered as a bearer for non-priority traffic.

Cause

All the NRF peers for service nnrf-nfm or nnrf-disc are block-listed after failure responses or response timeouts.

Effect

The block list duration is not applied. All NRF peers are sending failure responses or the responses time out. The Gateway continuously retries service requests to all peers.

Cause

A change in the reference point peer state during path management. The supported trap event values are the following: Added - raised when a new peer is identified due to incoming messages Up - raised when a peer moves to UP state, for a SGW peer, this state change happens when a CS Req is received. for PGW peers, this state change happens when a CS Resp from the PGW peer is received (this is to make sure that Path UP trap is generated only for a real PGW peer in case of GTP-C redirection) Down - raised when a peer moves to the FAULT state while detecting a path management failure. Idle - raised when a peer moves to the IDLE state after session cleanup is done due to path management Failure/ Detach/Admin delete Restart - raised when a peer restart is detected, it is associated with Peer RESTART state Deleted - raised when a peer entry is deleted due to a peer aging out, a peer ages out when it is Idle for more than the Age Out Interval.

Default severity

Source stream

main

Message format string

Card oper state-$tmnxMobGwSysGroupCardRedState$.

Cause

A card failure changes the card redundancy state to NOTVALID. When an active card goes down, the standby card becomes active which triggers a state change to active. When a STANDBYINPROG card becomes in sync with the active card, the state changes to standby.

Effect

When the card goes down, it will not be able to provide any mobile gateway services supported by the system.

Recovery

If the card goes down, the operator's assistance is needed to get the card back online.
