Table 51. Descriptions of Shared Ethernet Adapter failover statistics
Statistic Description
High availability
Control Channel PVID
Port VLAN ID of the virtual Ethernet adapter used as the control channel.
Control Packets in
Number of packets received on the control channel.
Control Packets out
Number of packets sent on the control channel.
Packet types
Keep-Alive Packets
Number of keep-alive packets received on the control channel. Keep-alive packets are received on the backup Shared Ethernet Adapter while the primary Shared Ethernet Adapter is active.
Recovery Packets
Number of recovery packets received on the control channel. Recovery packets are sent by the primary Shared Ethernet Adapter when it recovers from a failure and is ready to be active again.
Notify Packets
Number of notify packets received on the control channel. Notify packets are sent by the backup Shared Ethernet Adapter when it detects that the primary Shared Ethernet Adapter has recovered.
Limbo Packets
Number of limbo packets received on the control channel. Limbo packets are sent by the primary Shared Ethernet Adapter when it detects that its physical network is not
operational, or when it cannot ping the specified remote host (to inform the backup that it needs to become active).
Table 51. Descriptions of Shared Ethernet Adapter failover statistics (continued)
Statistic Description
State The current state of the Shared Ethernet Adapter.
INIT The Shared Ethernet Adapter failover protocol has just been initiated.
PRIMARY
The Shared Ethernet Adapter is actively connecting traffic between the VLANs to the network.
BACKUP
The Shared Ethernet Adapter is idle and not connecting traffic between the VLANs and the network.
RECOVERY
The primary Shared Ethernet Adapter recovered from a failure and is ready to be active again.
NOTIFY
The backup Shared Ethernet Adapter detected that the primary Shared Ethernet Adapter recovered from a failure and that it needs to become idle again.
LIMBO
One of the following situations is true:
v The physical network is not operational.
v The physical network’s state is unknown.
v The Shared Ethernet Adapter cannot ping the specified remote host.
Bridge Mode Describes to what level, if any, the Shared Ethernet
Adapter is currently bridging traffic.
Unicast
The Shared Ethernet Adapter is only sending and receiving unicast traffic (no multicast or broadcast traffic). To avoid broadcast storms, the Shared Ethernet Adapter sends and receives unicast traffic only while it is in the INIT or the RECOVERY states.
All The Shared Ethernet Adapter is sending and receiving all types of network traffic.
None The Shared Ethernet Adapter is not sending or receiving any network traffic.
Number of Times Server became Backup Number of times the Shared Ethernet Adapter was active and became idle because of a failure.
Number of Times Server became Primary Number of times the Shared Ethernet Adapter was idle and became active because the primary Shared Ethernet Adapter failed.

Statistic Description
High Availability Mode How the Shared Ethernet Adapter behaves regarding the Shared Ethernet Adapter failover protocol.
Auto The Shared Ethernet Adapter failover protocol determines whether the Shared Ethernet Adapter acts as the primary Shared Ethernet Adapter or as the backup Shared Ethernet Adapter.
Standby
The Shared Ethernet Adapter operates as a backup if there is another Shared Ethernet Adapter available to act as the primary. Standby causes a primary Shared Ethernet Adapter to become a backup Shared Ethernet Adapter if there is another Shared Ethernet Adapter that can become the primary Shared Ethernet Adapter.
Priority
Specifies the trunk priority of the virtual Ethernet adapters of the Shared Ethernet Adapter. It is used by the Shared Ethernet Adapter protocol to determine which Shared Ethernet Adapter acts as the primary Shared Ethernet Adapter and which Shared Ethernet Adapter acts as the backup Shared Ethernet Adapter. Values range from 1 to 12, where a lower number is favored to act as a primary Shared Ethernet Adapter.
Example statistics
Running the entstat -all command returns results similar to the following:
