Modifying a Server
The configuration tabs for a server are displayed automatically when a server is added to the system, or by selecting
the server name from the left frame Configuration Tree.
1. Log into the Administrative Interface using a login that has at least
write
access for the cluster that contains the
server (see “Logging In” on page 52).
2. In the left frame, select the name of the server to modify. The server
Configuration
tab opens in the right frame:
See the table below for an explanation of the server
Configuration
tab parameters:
ip
The dotted decimal IP address of the server. This is the address
Equalizer uses to communicate with the server.
port
Enter 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 protocol clusters, a cluster
port range can be
defined. These are the ports on the Equalizer to be used to send traffic
to the servers 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. See “Adding a Server to a Cluster” on page 142 for more
information on defining a port range and port redirection.
probe port
By default, the server probe port field is set to zero and the Equalizer
uses the server’s port field value for all TCP and ACV probes. If probe
port is not zero, Equalizer uses the value specified as the port for all
TCP and ACV probes.
Note : For servers in Layer 7 HTTPS clusters , set probe port to
something other than 443, since Equalizer communicates with the
servers via HTTP. In many configurations, it is set to the server
port .
(Note that the server agent port , set on the cluster, remains a
separate port that is used only for server agent communication.)
