Chapter 5 Configuring Real Servers and Server Farms
Configuring Real Servers
To configure real servers, perform this task:
This example shows how to create real servers:
Router(config-module-csm)# serverfarm serverfarm
Router(config-slb-sfarm)# real 10.8.0.7
Router(config-slb-real)# inservice
Router(config-slb-sfarm)# real 10.8.0.8
Router(config-slb-real)# inservice
Router(config-slb-sfarm)# real 10.8.0.9
Router(config-slb-real)# inservice
Router(config-slb-sfarm)# real 10.8.0.10
Router(config-slb-real)# inservice
Command Purpose
Step 1
Router(config-slb-sfarm)# real
ip-address [ port ]
Identifies a real server as a member of the server farm
and enters the real server configuration mode. An
optional translation port can also be configured
1, 2
.
1. Enter the exit command to leave a mode or submode. Enter the end command to return to the menu’s top level.
2. The no form of this command restores the defaults.
Step 2
Router(config-slb-real)# weight
weighting-value
(Optional) Sets the weighting value for the virtual server
predictor algorithm to assign the server’s workload
capacity relative to the other servers in the server farm if
the round robin or least connection is selected
2
.
Note The only time the sequence of servers starts over
at the beginning (with the first server) is when
there is a configuration or server state change
(either a probe or DFP agent).
When the least connection predictor is configured, a
slow-start mechanism is implemented to avoid sending a
high rate of new connections to the servers that have just
been put in service.
Step 3
Router(config-slb-real)# maxconns
max-conns
(Optional) Sets the maximum number of active
connections on the real server
2
. When the specified
maximum is reached, no more new connections are sent
to that real server until the number of active connections
drops below the minimum threshold.
Step 4
Router(config-slb-real)# minconns
min-conns
(Optional) Sets the minimum connection threshold
2
.
Step 5
Router(config-slb-real)# inservice
Enables the real server for use by the CSM
2 3
.
3. Repeat Steps 1 through 5 for each real server you are configuring.
Step 6
Router# show module csm slot [sfarm
serverfarm-name ] [detail]
(Optional) Displays information about configured real
servers. The sfarm option limits the display to real
servers associated with a particular virtual server. The
detail option displays detailed real server information.
Step 7
Router# show module csm slot [vserver
virtserver-name ] [client ip-address ]
[detail]
Displays active connections to the CSM. The vserver
option limits the display to connections associated with
a particular virtual server. The client option limits the
display to connections for a particular client. The detail
option displays detailed connection information.
