Viewing Cluster Interfaces

Description

This command shows the state of the Cluster Member interfaces and the virtual cluster interfaces.

ClusterXL treats the interfaces as Critical Devices. ClusterXL makes sure that interfaces can send and receive CCP packets.

ClusterXL also sets the required minimal number of functional interfaces to the largest number of functional interfaces ClusterXL detected since the last reboot. If the number of functional interfaces is less than the required number, ClusterXL declares the Cluster Member as failed and starts a failover. The same applies to the synchronization interfaces, where only good synchronization interfaces are counted.

When an interface is DOWN, it means that the interface cannot receive or send CCP packets, or both. An interface may also be able to receive, but not send CCP packets. The time you see in the command's output is the number of seconds that elapsed since the interface was last able to receive or send a CCP packet.

Syntax

Shell	Command
Gaia Clish	`set virtual-system <VSID>` `show cluster members interfaces {all \| secured \| virtual \| vlans}`
Expert mode	`cphaprob [-vs all] [-a] [-m] if`

Where:

Command	Description
`show cluster members interfaces all`	Shows full list of all cluster interfaces: including the number of required interfaces including Network Objective including VLAN monitoring mode, or list of monitored VLAN interfaces
`show cluster members interfaces secured`	Shows only cluster interfaces (Cluster and Sync) and their states: without Network Objective without VLAN monitoring mode without monitored VLAN interfaces
`show cluster members interfaces virtual`	Shows full list of cluster virtual interfaces and their states: including the number of required interfaces including Network Objective without VLAN monitoring mode without monitored VLAN interfaces
`show cluster members interfaces vlans`	Shows only monitored VLAN interfaces
`cphaprob if`	Shows only cluster interfaces (Cluster and Sync) and their states: without Network Objective without VLAN monitoring mode without monitored VLAN interfaces
`cphaprob -a if`	Shows full list of cluster interfaces and their states: including the number of required interfaces including Network Objective without VLAN monitoring mode without monitored VLAN interfaces
`cphaprob -a -m if`	Shows full list of all cluster interfaces and their states: including the number of required interfaces including Network Objective including VLAN monitoring mode, or list of monitored VLAN interfaces

Output

The output of these commands must be identical to the configuration in the cluster object's Network Management page in SmartConsole.

Example

Field, or Text

Description

CCP mode

Shows the CCP mode.

The default mode is Unicast.

Important - In R81, the CCP always runs in the unicast mode.

Required interfaces

Shows the total number of monitored cluster interfaces, including the Sync interface.

This number is based on the configuration of the cluster object > Network Management page.

Required secured interfaces

Shows the total number of the required Sync interfaces.

This number is based on the configuration of the cluster object > Network Management page.

Non-Monitored

This means that Cluster Member does not monitor the state of this interface.

In SmartConsole, in the cluster object > Network Management page, administrator configured the Network Type Private for this interface.

This means that Cluster Member monitors the state of this interface.

The current cluster state of this interface is UP, which means this interface can send and receive CCP packets.

In SmartConsole, in the cluster object > Network Management page, administrator configured one of these Network Types for this interface: Cluster, Sync, or Cluster + Sync.

DOWN

This means that Cluster Members monitors the state of this interface.

The current cluster state of this interface is DOWN, which means this interface cannot send CCP packets, receive CCP packets, or both.

In SmartConsole, in the cluster object > Network Management page, administrator configured one of these Network Types for this interface: Cluster, Sync, or Cluster + Sync.

(S)

This interface is a Sync interface.

In SmartConsole, in the cluster object > Network Management page, administrator configured one of these Network Types for this interface: Sync, or Cluster + Sync.

(LM)

This interface is configured in the $FWDIR/conf/cpha_link_monitoring.conf file.

Cluster Member monitors only the link on this interface (does not monitor the received or sent CCP packets).

See Configuring Link Monitoring on the Cluster Interfaces.

(HA)

This interface is a Bond interface in High Availability mode.

(LS)

This interface is a Bond interface in Load Sharing mode.

Virtual cluster interfaces

Shows the total number of the configured virtual cluster interfaces.

This number is based on the configuration of the cluster object > Network Management page.

No VLANs are monitored on the member

Shows the VLAN monitoring mode - there are no VLAN interfaces configured on the cluster interfaces.

Monitoring mode is Monitor all VLANs: All VLANs are monitored

Shows the VLAN monitoring mode - there are some VLAN interfaces configured on the cluster interfaces, and Cluster Member monitors all VLAN IDs.

Monitoring mode is Monitor specific VLAN: Only specified VLANs are monitored

Shows the VLAN monitoring mode - there are some VLAN interfaces configured on the cluster interfaces, and Cluster Member monitors only specific VLAN IDs.
