Usage Guidelines
If no options are specified, the command displays information about all real servers.
In a configuration with stateful backup, if a probe changes state at the same time that the primary IOS SLB device fails over to the backup IOS SLB device, the output from the show ip slb reals command for the backup device displays the state of the probe before the failover, not the actual current state.
Examples
The following is sample output from the show ip slb reals command:
Router# show ip slb reals

Field

Description
|
real |
IP address of the real server about which information is being displayed. Used to identify each real server. Information about each real server is displayed on a separate line. |
farm name |
Name of the server farm or firewall farm with which the real server is associated. |
weight |
Weight assigned to the real server. The weight identifies the real server's capacity, relative to other real servers in the server farm. |
state |
Current state of the real server. •DFP_THROTTLED—The Dynamic Feedback Protocol (DFP) agent sent a weight of 0 for this real server (send no further connections to this real server). •FAILED—The real server has failed as a result of either no response or reset (RST) responses to client traffic. (See the faildetect numconns (real server) command for more information about controlling tolerance for no responses and RSTs.) The real server has been removed from use by the predictor algorithms. The retry timer has started. •MAXCONNS_THROTTLE—The number of connections on the real server exceeds the configured maximum number of simultaneous active connections (maxconns). •OPERATIONAL—The real server is functioning properly and is being used for load-balancing. •OPER_WAIT—The real server is waiting to become operational (waiting for a timeout or some other condition to be met). •OUTOFSERVICE—The real server was configured with no inservice and has been removed from the load-balancing predictor lists. •PROBE_FAILED—The probe has succeeded in the past but has currently failed. This failure might occur at the same time user connections fail, or it might not. •PROBE_TESTING—The probe has never succeeded, due to no response. The initial probe timed out waiting for a success. |
| |
•READY_TO_TEST—The real server is queued for testing after being in FAILED state until the retry timer expired. •TESTING—The real server is queued for assignment. When a single user connection is assigned to a real server that is in READY_TO_TEST state, the real server is placed in TESTING state. If the test succeeds, the real server is placed back in OPERATIONAL state. •TEST_WAIT—The real server is waiting to begin testing (waiting for a timeout or some other condition to be met). |
conns |
Number of connections associated with the real server. In general packet radio service (GPRS) load balancing, number of sessions associated with the real server. In per-packet server load balancing, number of request packets that have been load balanced to each real server, using the connection count. |

Field
|
Description
|
Pkts via normal switching |
Number of packets handled by IOS SLB via normal switching since the last time counters were cleared. Normal switching is when IOS SLB packets are handled on normal IOS switching paths (CEF, fast switching, and process level switching). |
Pkts via special switching |
Number of packets handled by IOS SLB via special switching since the last time counters were cleared. Special switching is when IOS SLB packets are handled on hardware-assisted switching paths. |
Pkts via slb routing |
Number of packets handled by IOS SLB via SLB routing since the last time counters were cleared. |
Pkts dropped |
Number of packets dropped or consumed by IOS SLB since the last time counters were cleared. The Pkts dropped field can increase for one or more of the following reasons: •Pings and other Internet Control Message Protocol (ICMP) packets addressed to a virtual IP address are dropped. •TCP data packets in which the conn entry is not available as a result of an idle timeout, failure of a probe, or failure of a real server, are dropped. •UDP traceroute packets addressed to a virtual IP address are dropped. •UDP packets addressed to a virtual IP address with a port number other than the one configured in the virtual server are dropped. If the virtual server uses the any 0 port number, IOS SLB forwards the UDP packets to the real server. •Fragmented packets that cannot be reassembled are dropped. |
Connections Created |
Number of connections (or sessions, in general packet radio service [GPRS] load balancing and the Home Agent Director) created since the last time counters were cleared. |
Connections Established |
Number of connections (or sessions, in GPRS load balancing and the Home Agent Director) created and that have become established since the last time counters were cleared. |
Connections Destroyed |
