Managing Match Rules
Equalizer Installation and Administration Guide 129
The Default Match Rule
All Layer 7 clusters created via the Equalizer Administration Interface start with a single match rule
(named
Default) that matches all requests and selects all servers.
match Default {
any()
} then {
servers = all;
}
The default rule specifies that all servers defined in the cluster should be used for load balancing the
request, and that all flag settings for the request will be inherited from the cluster flag settings. This
rule is always the last match rule in the ordered list of match rules for a cluster. You cannot modify,
delete, or move this match rule.
The Default rule can be viewed by clicking in the left frame on match Default for any Layer 7
cluster. (If you have not created a Layer 7 cluster, see “Working with Virtual Clusters” on page 66).
Figure 58 shows the default match rule for a cluster with two servers.

Note that although the Default match rule cannot be modified or deleted, it can be overridden by
placing a rule prior to it that selects any() request, and selects other servers and flags than the
Default rule.
The following section shows you how to create a new Match Rule.
Creating a New Match Rule
To add a match rule to a virtual cluster, follow this general procedure:
1. Log into the Equalizer Administration Interface in edit mode.
2. In the left frame, click the name of the Layer 7 cluster to which you want to add the rule. The
cluster screen appears in the right frame.
