Taking Clusters and Servers On/Off Line
Alcatel-Lucent’s Server Load Balancing (SLB)
show
commands provide tools to monitor traffic and trou-
bleshoot problems. These commands are described in
“Displaying Server Load Balancing Status and
. If problems are identified, you can use the
to administratively disable an entire SLB cluster or the
command to administra-
tively disable individual servers within an SLB cluster. These commands are described in the following
sections.
Taking a Cluster On/Off Line
The following subsections describe how to bring an SLB cluster on line and how to take it off line with the
command.
Bringing an SLB Cluster On Line
You can bring an administratively disabled SLB cluster on line with the
command by entering
ip slb cluster
, the name of the SLB cluster, and
admin-state enable
.
For example, to bring an SLB cluster called “WorldWideWeb” on line, you would enter:
-> ip slb cluster WorldWideWeb admin-state enable
Taking an SLB Cluster Off Line
You can take a Server Load Balancing (SLB) cluster off line with the
command by entering
ip slb cluster
, the name of the SLB cluster, and
admin-state disable
.
For example, to take an SLB cluster called “WorldWideWeb” off line, you would enter:
-> ip slb cluster WorldWideWeb admin-state disable
Taking a Server On/Off Line
The following subsections describe how to bring a physical server on line and how to take it off line with
the
Note.
The
ip slb server ip cluster
command is also used to add or remove physical servers from an SLB
“Assigning Servers to and Removing Servers from a Cluster” on page 23-14
Bringing a Server On Line
You bring an administratively disabled server in an SLB cluster on line with the
command by entering
ip slb server
, the IP address of the server you want to enable in dotted decimal
format,
cluster
, the name of the SLB cluster to which the server belongs, and
admin-state enable
.
For example, to administratively enable a server with an IP address of 10.105.16.121 that belongs to an
SLB cluster called “Web_Server”, you would enter:
-> ip slb server ip 10.105.16.121 cluster Web_Server admin-state enable
