predictor Configuring Load Sharing Network Address Translation (LSNAT)
Enterasys Matrix DFE-Gold Series Configuration Guide 19-9
Defaults
None.
Mode
Routercommand,SLBServerFarmConfigurat ionmode:Matrix>Router(config‐slb‐sfarm)#
Usage
Forbackwardscompatibility,enteringaportnumberisoptionalforTCP sessionpersistenceonly.
However,therecommendedprocedureistoalwaysconfigureaportnumberforarealserver.
Allrealserversinthesameserverfarmshouldbeconfiguredtousethesameport.
The“no”formofthiscommandremoves
theserverfromtheserverfarm.
Example
Thisexampleshowshowtoaddarealserver10.1.2.3totheserverfarmnamed“httpserver”and
toconfiguretheportnumbertobeusedfortheserviceprovidedbythisserver:
Matrix>Router(config)#ip slb serverfarm httpserver
