LSF Version 7.3 - Platform LSF Configuration Reference

If a range is specified with fewer fields than an IP address such as 10.161, it is considered as
10.161.*.*.
Address ranges are validated at configuration time so they must conform to the required
format. If any address range is not in the correct format, no hosts will be accepted as LSF
floating clients, and an error message will be logged in the LIM log.
This parameter is limited to 2048 characters.
For IPv6 addresses, the double colon symbol (::) indicates multiple groups of 16-bits of zeros.
You can also use (::) to compress leading and trailing zeros in an address filter, as shown in
the following example:
FLOAT_CLIENTS_ADDR_RANGE=1080::8:800:20fc:*
This definition allows hosts with addresses 1080:0:0:0:8:800:20fc:* (three leading zeros).
You cannot use the double colon (::) more than once within an IP address. You cannot use a
zero before or after (::). For example, 1080:0::8:800:20fc:* is not a valid address.
Notes
After you configure FLOAT_CLIENTS_ADDR_RANGE, check the lim.log.host_name file
to make sure this parameter is correctly set. If this parameter is not set or is wrong, this will
be indicated in the log file.
Examples
FLOAT_CLIENTS_ADDR_RANGE=100
All IPv4 and IPv6 hosts with a domain address starting with 100 will be allowed access.
•
To specify only IPv4 hosts, set the value to 100.*
•
To specify only IPv6 hosts, set the value to 100:*
FLOAT_CLIENTS_ADDR_RANGE=100-110.34.1-10.4-56
All client hosts belonging to a domain with an address having the first number between 100
and 110, then 34, then a number between 1 and 10, then, a number between 4 and 56 will be
allowed access. Example: 100.34.9.45, 100.34.1.4, 102.34.3.20, etc. No IPv6 hosts are allowed.
FLOAT_CLIENTS_ADDR_RANGE=100.172.1.13 100.*.30-54 124.24-*.1.*-34
All client hosts belonging to a domain with the address 100.172.1.13 will be allowed access.
All client hosts belonging to domains starting with 100, then any number, then a range of 30
to 54 will be allowed access. All client hosts belonging to domains starting with 124, then from
24 onward, then 1, then from 0 to 34 will be allowed access. No IPv6 hosts are allowed.
FLOAT_CLIENTS_ADDR_RANGE=12.23.45.*
All client hosts belonging to domains starting with 12.23.45 are allowed. No IPv6 hosts are
allowed.
FLOAT_CLIENTS_ADDR_RANGE=100.*43
The * character can only be used to indicate any value. In this example, an error will be inserted
in the LIM log and no hosts will be accepted to become LSF floating clients. No IPv6 hosts are
allowed.
FLOAT_CLIENTS_ADDR_RANGE=100.*43 100.172.1.13
