• Monitored Interfaces—Displays the number of interfaces whose health you are monitoring for
failover.
• failover replication http—Specifies that HTTP replication is enabled.
• Group x Last Failover—Displays the time and date the last failover occurred for each failover group.
• This Host/Other Host —For each host in the failover pair, the following information is shown:
–
Primary or Secondary—Displays whether the unit is the primary or secondary unit.
–
Group x—For each failover group, the following information is shown:
State—Active or Standby Ready.
Active Time—The amount of time, in seconds, that the failover group has been in the active
state.
–
context_name Interface name (n.n.n.n)—For each interface, the display shows the IP address
currently being used on each unit, as well as one of the following conditions.
Failed—The interface has failed.
Link Down—The interface line protocol is down.
Normal—The interface is working correctly.
No Link—The interface has been administratively shut down.
Unknown—The security appliance cannot determine the status of the interface.
(Waiting)—The interface has not yet received any polling messages from the other unit.
Testing—The interface is being tested.
Stateful Failover Logical Updates Statistics—The following fields relate to the Stateful Failover feature.
If the Link field shows an interface name, then the Stateful Failover statistics are shown.
Note Stateful Failover is not supported on the ASA 5505 series adaptive security appliance. These statistics
do not appear in ASDM running on an ASA 5505 security appliance.
• Link—Displays one of the following:
–
interface_name—The interface used for the Stateful Failover link.
–
Unconfigured—You are not using Stateful Failover.
• Stateful Obj—For each field type, the following statistics are displayed:
xmit—Number of transmitted packets to the other unit
xerr—Number of errors that occurred while transmitting packets to the other unit
rcv—Number of received packets
rerr—Number of errors that occurred while receiving packets from the other unit
The following are the stateful object field types:
–
General—Sum of all stateful objects.
–
sys cmd—Logical update system commands; for example, LOGIN and Stay Alive.
–
up time—Up time, which the active unit passes to the standby unit.
–
RPC services—Remote Procedure Call connection information.
–
TCP conn—TCP connection information.
