Configuring SLB Probes Configuring Server Load Balancing
page 23-18 OmniSwitch AOS Release 7 Network Configuration Guide June 2013
Taking a Server Off Line
You can administratively disable a server in an SLB cluster and take it off line with the ip slb server ip
cluster command by entering ip slb server , the IP address of the server you want to disable in dotted
decimal format, cluster , the name of the SLB cluster to which the server belongs, and admin-state
disable .
For example, to administratively disable a server with an IP address of 10.105.16.123 that belongs to an
SLB cluster called “Web_Server”, you would enter:
-> ip slb server ip 10.105.16.123 cluster Web_Server admin-state disable
Configuring SLB Probes
Server Load Balancing (SLB) probes allow you to check the health of logical clusters and physical
servers. Supported features include:
•
Support for server health monitoring using Ethernet link state detection
•
Support for server health monitoring using IPv4 ICMP ping
•
Support for server health monitoring using a Content Verification Probe
Creating SLB Probes
To create an SLB probe use the ip slb probe command by entering the command followed by the
user-configured probe name and the probe type, which can be any one of the following listed in the table
below:
For example, to create an HTTP SLB probe called “server_probe1”, enter:
-> ip slb probe server_probe1 http
You can configure up to 20 probes on a switch.
Deleting SLB Probes
To delete an SLB use the no form of the ip slb probe command by entering no ip slb probe followed by
the probe name. For example, to delete an SLB probe called “server_probe1”, enter:
-> no ip slb probe server_probe1
