/cfg/slb/gslb/rule
Rule Menu
Rules enable the GSLB selection to use different metric preferences based on time-of-day. You can configure one or more rules on each domain. Each rule has a metric preference list. The GSLB selection selects the first rule that matches the domain and starts with the first metric in the metric preference list of the rule.

GSLB Rule Configuration Menu Options (/cfg/slb/gslb/rule) 
Command Syntax and Usage
name <128 character rule name | none>
 
Specifies a descriptive name for the rule.
metric <metric (1-16)>
 
Displays the Rule Metric menu. To view this menu, see /cfg/slb/gslb/rule/metric Global SLB Rule Metric Menu.
start <hour (0-23) minutes (0-59)>
 
Defines the start time for the rule.
Default: 0
end <hour (0-23) minutes (0-59)>
 
Defines the end time for the rule.
Default: 0
ttl <time to live in seconds (0-65535)>
 
Specifies the duration that the DNS response from Alteon (indicating the site of best service) remains in the cache of DNS servers. A lower value may increase the ability of the GSLB system to adjust to sudden changes in traffic load, but generates more DNS traffic. Higher numbers may reduce the amount of DNS traffic, but may slow the GSLB’s response to sudden traffic changes.
Values: 0 – 65535
Default: 60
rr <rr (1-10)>
 
Sets the number of DNS resource records are returned in the DNS response.
Default: 2
dname <253 character (wildcard "*" allowed) domain name> | none
 
Defines the domain name or sub-domain name for the rule for network preference.
You can use the wildcard “*” when creating the sub-domain name.
Number of characters: 1 – 253
Default: none
namesrvr
 
Defines the nameserver group for the domain name or none (supports auto-completion).
Default: none
smask
 
Specifies the source IP subnet mask for the phash metric.
Default: 255.255.255.0
sprefix (1-128)
 
Specifies the source IPv6 prefix for the phash metric.
Default: 64
timeout (0-1440)
 
Specifies the timeout in minutes for the phash metric.
Default: 60
persist [domain|ip]
 
Specifies whether to perform hashing by source IP address and domain, or by source IP address only. Relevant for hash, phash, and minmiss metrics.
Note: If ednsprst is enabled and there is an EDNS extension in the query, Alteon uses that IP address, otherwise Alteon uses the packet source IP address.
Default: domain
ednsprst [enable|disable]
 
Enables or disables the use of the Enable DNS value for DNS persistence for the rule.
Default: disabled
fallback [enable|disable]
 
Specifies the action that Alteon performs when the network metric returns no IP addresses.
*enabled — When the network metric returns no IP addresses, the next metric considers all possible IP addresses for selection.
*disabled — When the network metric returns no IP addresses, the query is not served.
Default: disabled
ena
 
Enables the rule.
dis
 
Disables the rule.
del
 
Deletes the rule.
cur
 
Displays the current rule configuration.
