Syntax ADD WANLB HEALthcheck[=1..3] HOst=hostaddress
Description This command adds a healthcheck host to the WAN load balancer. Up to three
hosts can be added. The WAN load balancer will use these hosts for checking
the status of its resources.
You can display details of the healthcheck hosts by using the show wanlb
healthcheck command on page 1-36. To display the status of the healthcheck
hosts for each resource, use the show wanlb resource command on page 1-37
command. To delete a host, use the delete wanlb healthcheck command.
Examples To add two healthcheck hosts that have the IP address 202.36.8.8 and
www.vpn-site.com respectively, use the commands:
add wanlb heal ho=202.36.8.8
add wanlb heal ho=www.vpn-site.com
Related Commands delete wanlb healthcheck

show wanlb resource
Parameter Description
1..3 Specifies the index number assigned to a host.
HOst The hostaddress that will receive the WAN load balancer
healthchecks. This can be either an IP address or domain name.
The healthcheck responses for a host can change the
operational state of the WAN load balancer resources. Also, in
the weighted fast response mode, the host is used for resource
selection. For this reason you should choose your host sites with
care.
For your healthcheck host, you could select a website critical to
your organisation. However, public servers can get overloaded
with requests and the response time may be less representative
of the WAN link. Servers in a remote private network, or an
intermediate node within your ISP, are recommended for use as
healthcheck hosts. You can enter the IP address or the domain
name (e.g.,www.critical-site.com) of your selected host.
