Chapter 6 Configuring Real Servers and Server Farms
Managing Real Servers
Viewing All Real Servers
To view all real servers, choose Config > Operations > Real Servers. The Real Servers table displays
the following information in Table 6-2 by default:
In the previous table, Disabled indicates that either the information is not available from the database or
that it is not being collected via SNMP. To identify any SNMP-related issues, select the real server’s
virtual context in the object selector. If there are problems with SNMP, SNMP status will appear in the
upper right above the content pane.
Table 6-2 Real Server Table Fields
Item Description
Name Real server name.
IP address Real server IP address.
Port Port used to by the real server for communications.
Vservers Associated virtual server.
Context Associated virtual context.
Admin Administrative state of the real server: In Service, Out Of Service, or In Service Standby.
Oper Operational state of the real server (see Table 6-3 for descriptions of real server operational states).
Conn Number of current connections.
Wt Current server weight.
Locality Locality requires that you configure the Dynamic Workload Scaling on the ACE (see the “Configuring
Dynamic Workload Scaling” section on page 6-14).
Location of the real server, which must be a VM and not a physical server. Possible locality states are
as follows:
• N/A—he ACE cannot determine the real server location (local or remote). A possible cause for
this issue is that Dynamic Workload Scaling is not configured correctly.
• Local—The real server is located in the local network.
• Remote—The real server is located in the remote network. The ACE bursts traffic to this server
when the CPU or memory usage of the local real server reaches the specified maximum threshold
value.
Stat Age Time as of the page load when the SNMP values were polled.
Server Farm Associated server farm.
Table 6-3 Real Server Operational States

ARP Failed An ARP request to this server has failed.
Failed The server has failed and will not be retried for the amount of time specified
