Viewing Cluster Interfaces

In the R82.00.X releases, this command is available starting from the R82.00.00 version.

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.

  • 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

Table: Description of the output fields

Field, or Text

Description

CCP mode

Shows the CCP mode.

The default mode is Unicast.

Important - In R82.00.X versions, the CCP always runs in the unicast mode.

Required interfaces

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

Required secured interfaces

Shows the total number of the required Sync interfaces.

Non-Monitored

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

UP

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.

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.

(S)

This interface is a Sync interface.

(P)

This interface tries to probe its peer.

(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.

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.
