Modifying a Layer 7 Virtual Cluster

The configuration tabs for a cluster are displayed automatically when a cluster is added to the system, or by selecting
the cluster name from the left frame Configuration Tree. HTTP and HTTPS clusters parameters are divided among
the following tabs:
•

Layer 7 Required Tab

•
Layer 7 Probes Tab
•
Layer 7 Persistence Tab
•
Layer 7 Networking Tab
•
Layer 7 Security > Certificates Tab (HTTPS only)
•
Layer 7 Security > SSL Tab (HTTPS only)
These are described in the following sections. To update the settings on any tab, make changes and select the
button to save them.

Enter the ip address, which is the dotted decimal IP address of the cluster.
The IP address of the cluster is the external address (for example,
199.146.85.0) with which clients connect to the cluster.
For HTTP and HTTPS protocol clusters, enter the port: the numeric port
number on the Equalizer to be used for traffic between the clients and the
cluster. For HTTP clusters, the port defaults to 80. For HTTPS clusters, the port
defaults to 443. This port also becomes the default port for servers added to
the cluster (though servers can use a different port number than the one used
by the cluster).
Used to define an IP subnet that is different from the subnet defined for the
cluster IP interface. If this is defined, it is assumed that the customer has the
proper routing in place for clients to access multiple IP subnets defined on the
Equalizer. The default is the netmask of the network interface for the cluster
IP.
Disable this cluster. The cluster IP address will not accept requests when this
flag is enabled.
ignore case causes all of the cluster's match rules to use case insensitive
comparisons when this box is checked. You can override this setting by
changing ignore case for a specific match rule.
spoof causes Equalizer to spoof the client IP address when Equalizer routes a
request to a server in a virtual cluster; that is, the IP address of the client is
sent to the server, not the IP address of the Equalizer. This option is on by
default. If you disable this option, the server receiving the request will see the
Equalizer's address as the client address because the TCP connection to the
client is terminated when the request is routed. When spoof is enabled, the
servers in the cluster must use the Equalizer as the default gateway for
routing.
If Express Hardware GZIP Compression is installed, the compress flag
appears in the HTTP and HTTPS cluster configuration screens. When the
compress cluster flag is enabled, Equalizer automatically detects requests to
the cluster from compression-capable browser clients and performs GZIP
compression on all cluster responses sent to that client. This effectively
enables compression for all clients using recent browser versions. Also see
"Layer 7 Networking Tab" on page 118.
