Firewall Mark
For entering a firewall mark integer value when bundling multi-port protocols or cre-
ating a multi-port virtual server for separate, but related protocols.
Device
The name of the network device to which you want the floating IP address defined in
the Virtual IP Address field to bind.
You should alias the public floating IP address to the Ethernet interface connected to
the public network.
Re-entry Time
An integer value that defines the number of seconds before the active LVS router
attempts to use a real server after the real server failed.
Service Timeout
An integer value that defines the number of seconds before a real server is considered
dead and not available.
Quiesce server
When the Quiesce server radio button is selected, anytime a new real server node
comes online, the least-connections table is reset to zero so the active LVS router
routes requests as if all the real servers were freshly added to the cluster. This op-
tion prevents the a new server from becoming bogged down with a high number of
connections upon entering the cluster.
Load monitoring tool
The LVS router can monitor the load on the various real servers by using either rup or
ruptime. If you select rup from the drop-down menu, each real server must run the
rstatd service. If you select ruptime, each real server must run the rwhod service.
Scheduling
The preferred scheduling algorithm from the drop-down menu. The default is
Weighted least-connection.
Persistence
Used if you need persistent connections to the virtual server during client transactions.
Specifies the number of seconds of inactivity allowed to lapse before a connection
times out in this text field.
