Redundancy node (redundancynode)

Redundancy node module contains information about TPO hot-backup nodes.

These information is only available on Cluster virtual IP mode.

Redundancy node OID is: .iptrade.tpo.redundancynode (.30191.2.7)

nodeNumber (.30191.2.7.1)

Contains the number of entries in nodeTable (see here after)

•SNMP syntax: Integer32

•type: punctual

•update rate: set once on system start, never updated

nodeTable (.30191.2.7.2)

Contains redundancy node entries

•SNMP syntax: table ( SEQUENCE OF … )

•table entry: nodeEntry (.30191.2.7.2.1)

•table fields: nodeIndex, nodeId, nodeName, nodeStatus, nodeConfId, nodeMacAddr, nodeLocalIP, nodeVIP (see description hereafter)

•table row ids: from 1 to X where ‘X’ is the number of nodes

•type: punctual

•update rate: filled at system start

nodeIndex (.30191.2.7.2.1.1)

Contains recorder entries index (inside recorder table)

•SNMP syntax: Integer32

•Table row are indexed from 1 to X where ‘X’ is the number of nodes

nodeId (.30191.2.7.2.1.2)

Contains node internal Id

•SNMP syntax: DisplayString

nodeName (.30191.2.7.2.1.3)

Contains node name

•SNMP syntax: DisplayString

nodeStatus(.30191.2.7.2.1.4)

Contains node status

•SNMP syntax: RedundancyNodeStatus

The RedundancyNodeStatus indicates the state of TPO redundancy:

-        Undefined: TPO is in Idle state

-        Ready: TPO has checked that all network parameters are OK

-        Learning: TPO leans the state of other TPOs of the cluster

-        Passive: TPO is in Passive state

-        SwapOnlinePending: TPO has added the virtual IP address in the local machine

-        SwapOnlineWaiting: TPO has sent ARP gratuitous message to the network and is waiting that is OK by binding the virtual IP address.

-        Active: TPO is in Active state and runs a config Id

-        Dropped: TPO is viewed as not connected

-        RestoreInProgress: Here is the transition when a passive TPO becomes active

-        Error: When a passive TPO fails to become active

nodeConfId (.30191.2.7.2.1.5)

Contains node name

•SNMP syntax:  Integer32

The value is -1 if there is not config Id associated to the node

nodeMacAddr (.30191.2.7.2.1.6)

Contains the Mac Address associated with the Node local IP address/Virtual IP address

•SNMP syntax:  PhysAddress

nodeLocalIP (.30191.2.7.2.1.7)

Contains the Node local IP address

•SNMP syntax:  IpAddress

Only IP v4 is supported

nodeVIP (.30191.2.7.2.1.8)

Contains the Virtual IP address

•SNMP syntax:  IpAddress

Only IP v4 is supported

nodeVarLastMacAddr (.30191.2.7.3)

Contains the Mac address associated with the last trap of the MAC/VIP change

•SNMP syntax:  PhysAddress

nodeVarLastVIP (.30191.2.7.4)

Contains the virtual IP address associated with the last trap of the MAC/VIP change

•SNMP syntax:   IpAddress
