Working with Clusters and Match Rules
UDP Cluster Configuration Persistence
The UDP Cluster
Configuration >Persistence
screen is used to configure
Sticky Netmask
values, Timeouts
and assign the Inter Cluster sticky flag to the selected UDP cluster. It can be accessed by
selecting a cluster from the left navigational pane and selecting the
Configuration > Persistence
tab.
Sticky Netmask
Enables sticky network aggregation for a subnet. Sticky network aggreg-
ation is applicable for Layer 4 and Layer 7 clusters. Sticky network aggreg-
ation enables Equalizer to correctly handle sticky connections from ISPs
that use multiple proxy servers to direct user connections. When you
enable sticky network aggregation, all the connections coming from a par-
ticular network are directed to the same server. (Typically, all the servers
in a proxy farm are on the same network.) The sticky netmask value indic-
ates which portion of the address Equalizer should use to identify par-
ticular networks. Values are:
0-32
for IPV4 clusters (default=32)
0-128
for IPV6 clusters
Inter-Cluster Sticky
With the inter-cluster sticky option, you can configure Equalizer to dir-
ect requests from a client to the same server on any available port that has
a current persistent connection in any cluster.Inter-Cluster Sticky is a
Layer 4 option that allows you to extend Layer 4 persistence across mul-
tiple server ports.
Sticky Time Out -
Sticky Timeout is the number of seconds that Equalizer should “remem-
ber” connections from clients. Valid values are from 0 (which disables
sticky connections) to 1073741823 seconds (or over 34 years). For more
information, refer to
"Enabling Sticky Connections"
