gslb site¶
The following operations can be performed on "gslb site":
add | rm | set | unset | show | stat
add gslb site¶
Creates a global server load balancing site.
Synopsys¶
add gslb site <siteName> [<siteType>] <siteIPAddress> [-publicIP <ip_addr|ipv6_addr|>] [-metricExchange ( ENABLED | DISABLED )] [-nwMetricExchange ( ENABLED | DISABLED )] [-sessionExchange ( ENABLED | DISABLED )] [-triggerMonitor <triggerMonitor>] [-parentSite <string>] [-clip <ip_addr|ipv6_addr|> [<publicCLIP>]]
Arguments¶
siteName
Name for the GSLB site. Must begin with an ASCII alphanumeric or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. Cannot be changed after the virtual server is created.
CLI Users: If the name includes one or more spaces, enclose the name in double or single quotation marks (for example, "my gslbsite" or 'my gslbsite').
siteType
Type of site to create. If the type is not specified, the appliance automatically detects and sets the type on the basis of the IP address being assigned to the site. If the specified site IP address is owned by the appliance (for example, a MIP address or SNIP address), the site is a local site. Otherwise, it is a remote site.
Possible values: REMOTE, LOCAL
Default value: NS_NORMAL
siteIPAddress
IP address for the GSLB site. The GSLB site uses this IP address to communicate with other GSLB sites. For a local site, use any IP address that is owned by the appliance (for example, a SNIP or MIP address, or the IP address of the ADNS service).
publicIP
Public IP address for the local site. Required only if the appliance is deployed in a private address space and the site has a public IP address hosted on an external firewall or a NAT device.
metricExchange
Exchange metrics with other sites. Metrics are exchanged by using Metric Exchange Protocol (MEP). The appliances in the GSLB setup exchange health information once every second.
If you disable metrics exchange, you can use only static load balancing methods (such as round robin, static proximity, or the hash-based methods), and if you disable metrics exchange when a dynamic load balancing method (such as least connection) is in operation, the appliance falls back to round robin. Also, if you disable metrics exchange, you must use a monitor to determine the state of GSLB services. Otherwise, the service is marked as DOWN.
Possible values: ENABLED, DISABLED
Default value: ENABLED
nwMetricExchange
Exchange, with other GSLB sites, network metrics such as round-trip time (RTT), learned from communications with various local DNS (LDNS) servers used by clients. RTT information is used in the dynamic RTT load balancing method, and is exchanged every 5 seconds.
Possible values: ENABLED, DISABLED
Default value: ENABLED
sessionExchange
Exchange persistent session entries with other GSLB sites every five seconds.
Possible values: ENABLED, DISABLED
Default value: ENABLED
triggerMonitor
Specify the conditions under which the GSLB service must be monitored by a monitor, if one is bound. Available settings function as follows:
-
ALWAYS - Monitor the GSLB service at all times.
-
MEPDOWN - Monitor the GSLB service only when the exchange of metrics through the Metrics Exchange Protocol (MEP) is disabled.
MEPDOWN_SVCDOWN - Monitor the service in either of the following situations:
-
The exchange of metrics through MEP is disabled.
-
The exchange of metrics through MEP is enabled but the status of the service, learned through metrics exchange, is DOWN.
Possible values: ALWAYS, MEPDOWN, MEPDOWN_SVCDOWN
Default value: NSGSLB_TRIGMON_ALWAYS
parentSite
Parent site of the GSLB site, in a parent-child topology.
clip
Cluster IP used to connect to remote cluster site for GSLB autosync
Example¶
add site new_york LOCAL 192.168.100.12 -publicIP 65.200.211.139
