Node failure codes

Node failure codes are:

• HW Hardware monitoring

• MB Mbuf monitoring

• CS Cold Sync monitoring

• LB Loopback monitoring

• SP SPU monitoring

Node Status

• status of the node

• Local-domain-id—local domain identifier in four-node MNHA setup.

• Local-id—local node ID in four-node MNHA setup.

• Local-id—local identifier

• Local-IP—local IP address of the node

• Local Forwarding IP—Source IP address used to route the traffic (local interchassis datalink[ICD])

ICL Local-IP—IP address of ICL in the local domain

HA ICL Peer Information

• Peer Domain ID: Peer domain identifier in four-node MNHA setup.

• Peer Id—peer identifier

• IP address—peer IP address

• Interface—interface name

• Peer Forwarding IP—Destination IP address used to route the traffic (peer node's ICD)

• Interface—Interface used for ICD.

• Peer ICD Conn State—Status of ICD.

• Routing Instance—routing instance name

• Encrypted—data encrypted status

• Cold Sync Status—cold sync status of the node.

• Domain id—Domain identifier

• Peer id—Peer node identifier
  • IDL Conn State—status of IDL in peer node
  • SRG0 Cold Sync Status—cold sync status of the per node.
• Peer id: Peer node identifier
  • SRG0 Cold Sync Status—cold sync status of the peer node.

• ICL Conn State: status of ICL in peer node
• Cold Sync Status: cold sync status of the peer node.

• Domain id—Domain identifier

• Peer id—Peer node identifier
  • IDL Conn State—status of IDL in peer node
  • SRG0 Cold Sync Status—cold sync status of the per node.
• Peer id: Peer node identifier
  • SRG0 Cold Sync Status—cold sync status of the peer node.

Hardware monitoring

Services Redundancy Group

• Current State—current state of the node

• Peer Information—peer information

• Peer Id—peer identifier

SRG failure event codes

• BF BFD monitoring—monitor Bidirectional Forwarding Detection.

• IP IP monitoring—monitor IP address

• CP Control Plane monitoring—monitor control plane state

Services Redundancy Group

• Status—node status

• Activeness Priority—the node with the higher activeness priority become active for the service redundancy group.

• Services—Associated services for the SRG.

  • IPsec.

• Process Packet In Backup State—packet processing in Backup state.

• Control Plane State—Displays the Control plane cold sync readiness after taking over the backup role. Means the control plane finished syncing all the control plane data from the new active node.

  The options are:

  • READY—Active mode

  • READY/NOT READY—Backup node based on the actual state

  • N/A—in other states

• System Integrity Check—Displays if the hold timer is running and system integrity check is under progress. Applicable only in BACKUP and INELLIGIBLE state.

• Failure Events—Displays local service redundancy group related attribute failure events.

• Peer Information—Displays peer node information.

  • Peer Id— Peer node identification number.

  • Status—Displays status of the peer node. The options are Active/Backup/Ineligible/Unknown.

  • Health Status—Displays health status of the peer node as advertised last

    • HEALTHY—Peer node SRG state is healthy

    • UNHEALTHY—Peer node SRG state is unhealthy

    • UNKNOWN—Peer link is down

    • SRG NOT CONFIGURED—SRG not configured at peer node.

  • Failover Readiness—Displays Failover readiness of the peer node and applicable only in Active state.

    The options are:

  • READY—Peer’s healthy, control and data plane cold sync is complete and hence peer is ready for a failover. A manual failover can be done

  • NOT READY—Peer is either unhealthy, or data/control plane cold sync is pending

  • UNKNOWN—Peer’s failover readiness is awaited or if peer link is down

  • N/A—In all states other than Active.
