Load Balancing Special Services
>> Virtual Server 1 DNS Service # dnsslb ena
>> Virtual Server 1 DNS Service # dnstype both
3. In addition to the TCP settings, for the virtual server, if using a TCP-based DNS server, enable
delayed binding (if using a UDP-based DNS server, do not enable delayed binding).
>> Virtual Server 1 DNS Service # protocol tcp
>> Virtual Server 1 DNS Service# dbind ena
4. Define the hostnames used by servers 1 through 2.
>> /cfg/slb/layer7/slb/addstr DNSQ=any;TP=dns;HN=[abcdefg]+\\.com
>> /cfg/slb/layer7/slb/addstr DNSQ=any;TP=dns;HN=[hijklm]+\\.com
>> /cfg/slb/layer7/slb/addstr DNSQ=any;TP=dns;HN=[nopqrst]+\\.com
>> /cfg/slb/layer7/slb/addstr DNSQ=any;TP=dns;HN=[uvwxyz]+\\.com
Alternatively, use the interactive CLI. For example:
>> Server Load balance Resource# /cfg/slb/layer7/slb/addstr
Enter type of string [l7lkup|pattern]: l7lkup
Select Application (http|dns|other) [other]: dns
Enter DNS Type (dns, dnssec, any) [any]: dns
Enter DNS Query Type(s) (by number, query type name, or any) [any]: any
Enter DNS hostname or none [none]:
Note: When using the interactive menu the '\' is not inserted as in the regex format. The '\' is
used to cancel the '.' as a wildcard.
5. Define the DNS query types (used by servers 3 through 4).
# /cfg/slb/layer7/slb/addstr DNSQ=A,AAAA,MX;TP=dns
# /cfg/slb/layer7/slb/addstr DNSQ=A,AAAA,MX,DNSKEY;TP=dnssec
6. Apply and save your configuration changes.
For easy configuration and identification, each defined string has an ID attached, as shown in
the following table:
ID SLB String
1
any, cont 1024
2
DNSQ=any;TP=dns;HN=[abcdefg]+\.com, cont 1024
3
DNSQ=any;TP=dns;HN=[hijklm]+\.com, cont 1024
4
DNSQ=any;TP=dns;HN=[nopqrst]+\.com, cont 1024
5
DNSQ=any;TP=dns;HN=[uvwxyz]+\.com, cont 1024
6
DNSQ=A,AAAA,MX;TP=dns, cont 1024
7
DNSQ=A,AAAA,MX,DNSKEY;TP=dnssec, cont 1024
