cluster-instance
The following operations can be performed on “cluster-instance”:
| show | disable | enable | rm | add | unset | stat | set |
show cluster instance
Displays information about the cluster instance and its nodes.
Synopsis
show cluster instance [
Arguments
clId Unique number that identifies the cluster. Minimum value: 1 Maximum value: 16
Output
deadInterval Amount of time, in seconds, after which nodes that do not respond to the heartbeats are assumed to be down.If the value is less than 3 sec, set the helloInterval parameter to 200 msec
helloInterval Interval, in milliseconds, at which heartbeats are sent to each cluster node to check the health status.Set the value to 200 msec, if the deadInterval parameter is less than 3 sec
preemption Preempt a cluster node that is configured as a SPARE if an ACTIVE node becomes available.
adminstate Cluster Admin State.
quorumType Quorum Configuration Choices - “Majority” (recommended) requires majority of nodes to be online for the cluster to be UP. “None” relaxes this requirement.
propState Enable/Disable the execution of commands on the cluster. This will not impact the execution of commands on individual cluster nodes by using the NSIP.
inc This option is required if the cluster nodes reside on different networks.
nodegroup The node group in a Cluster system used for transition from L2 to L3.
processLocal By turning on this option packets destined to a service in a cluster will not under go any steering.
validMtu Correct MTU value that has to be set on backplane.
retainConnectionsOnCluster This option enables you to retain existing connections on a node joining a Cluster system or when a node is being configured for passive timeout. By default, this option is disabled.
heterogeneousFlag This field diplay if heterogeneous is detected in the cluster system.
backplaneBasedView View based on heartbeat only on bkplane interface
syncStatusStrictMode strict mode for sync status of cluster. Depending on the the mode if there are any errors while applying config, sync status is displayed accordingly. By default the flag is disabled.
dfdretainl2params flag to add ext l2 header during steering. By default the flag is disabled.
clusterProxyArp This field controls the proxy arp feature in cluster. By default the flag is enabled.
secureHeartbeats By turning on this option cluster heartbeats will have security enabled.
nodeId The unique number that identiies a cluster.
IPAddress The IP Address of the node.
flags The flags for this entry.
masterState Master state.
health Node Health state.
clusterHealth Node clusterd state.
effectiveState Node effective health state.
state Active, Spare or Passive. An active node serves traffic. A spare node serves as a backup for active nodes. A passive node does not serve traffic. This may be useful during temporary maintenance activity where it is desirable that the node takes part in the consensus protocol, but not serve traffic.
flag Cluster Flag.
operationalstate Cluster Operational State.
status Cluster Operational State.
isConfigurationCoordinator This argument is used to determine whether the node is configuration coordinator (CCO).
isLocalnode This argument is used to determine whether it is local node.
RSSKeyMismatch This argument is used to determine if there is a RSS key mismatch at cluster instance level.
PENumMismatch This argument is used to determine if there is a PE number mismatch at cluster instance level.
NodegroupStateWarning This argumnt is used to determind whether all the cluster nodes are bound to nodegroup with state set.
LicenseMismatch This argument is used to determine if there is a License mismatch at cluster instance level.
JumboNotSupported This argument is used to determine if Jumbo framework is not supported at cluster instance level.
ClusterNoHeartbeatOnNode HB is not seen on the backplane interface of member node
ClusterNoLinksetMBF MBF is enabled but linkset is not configured
ClusterNoSpottedIp There is no spotted SNIP or MIP
ClusterCLIPFailure CLIP movement failure. CLIP is not attached to CCO
ClusterHBHmacErrorDetected There is cluster hb hmac error detected, it could be due to version mismatch
NodeRSSKeyMismatch This argument is used to determine if there is a RSS key mismatch at cluster node level.
NodePENumMismatch This argument is used to determine if there is a PE missmatch at cluster node level.
NodeLicenseMismatch This argument is used to determine if there is a License mismatch at cluster node level.
NodeJumboNotSupported This argument is used to determine if Jumbo framework not supported at cluster node level.
stateflag State Flag.
operationalPropState Cluster Operational Propagation State.
devno count
Example
An example of the command’s output is as follows: 1)Cluster ID: 1 Dead Interval: 3 secs Hello Interval: 200 msecs Preemption: DISABLED Propagation: ENABLED Cluster Status: ENABLED(admin), ENABLED(operational), UP Member Nodes: Node ID Node IP Health Admin State Operational State ——- ——- —— ———– —————– 1) 1 1.1.1.1* UP ACTIVE ACTIVE(Configuration Coordinator) 2) 2 1.1.1.2 UP ACTIVE ACTIVE Done *: Local node
