Adding a Server (CLI)

Perform this procedure once for each real server that you want to add to Equalizer.

Enter the following:

eqcli > server [server name] proto tcp ip xxx.xxx.x.x port xx

where:

proto

The server protocol

The dotted decimal IP address of the server. Thisis the address Equalizer usesto

communicate with the server.

port

The numeric port number on the Equalizer to be used for traffic between Equalizer and

the server. The default is port 80. (Note that in

Layer 7 HTTPS

clusters, the server port

should be set to something other than 443 since Equalizer communicates with servers

in an HTTPS cluster via HTTP.)

For L4 UDP and L4 TCP protocolclusters, a cluster

port range

can be defined. These

are the ports on the Equalizer to be used to send traffic to the server pool in the cluster.

Port ranges allow Equalizer users to create a single cluster to control the traffic for

multiple, contiguous ports. The Port defined for a

server

in the cluster for which a port

range is defined indicates the port on the server that starts the range of ports to be

opened.

Note -

For servers in Layer 7 HTTPS clusters

, set Port to something other than 443, since Equalizer communicates

with the servers via HTTP. In many configurations, it is set to the server Port.

The server agent port, set on the cluster, remains a separate port that is used only for server agent communication.)

Modifying a Server (CLI)

Create a server and enter parameters for each server.Refer to "Server Commands" on page 168 for CLI

commands and use.

max_reuse_conn -

Sets the maximum number of permitted open connections for the server. Once this

limit is reached, no more traffic is routed to the server untilthe number of open

connections falls below this limit. This limit isset by default to 0, which means that there

is no maximum connections limit on the server. See "Maximum Connections

Limits, Responders, and Hot Spares" on page 255 for more information.

reuse_conn_to

The number of seconds after which a connection record for an idle server connection

in the reusable connection pool is removed, and the connection closed. The default

value is 0 seconds, which means that records in the reusable connections pool never

expire.

probe_l3 (flag)

Enabling this option sets up an alert on the server allows you to send email, log a

message to the system log, or both, whenever the server is marked up or down by

Layer 3 health check probes.
