ipv46:
description:
- "IPv4 or IPv6 address to assign to the virtual server."
ippattern:
description:
- >-
IP address pattern, in dotted decimal notation, for identifying packets to be accepted by the virtual
server. The IP Mask parameter specifies which part of the destination IP address is matched against
the pattern. Mutually exclusive with the IP Address parameter.
- >-
For example, if the IP pattern assigned to the virtual server is C(198.51.100.0) and the IP mask is
C(255.255.240.0) (a forward mask), the first 20 bits in the destination IP addresses are matched with
the first 20 bits in the pattern. The virtual server accepts requests with IP addresses that range
from C(198.51.96.1) to C(198.51.111.254). You can also use a pattern such as C(0.0.2.2) and a mask such as
C(0.0.255.255) (a reverse mask).
- >-
If a destination IP address matches more than one IP pattern, the pattern with the longest match is
selected, and the associated virtual server processes the request. For example, if virtual servers
C(vs1) and C(vs2) have the same IP pattern, C(0.0.100.128), but different IP masks of C(0.0.255.255) and
C(0.0.224.255), a destination IP address of C(198.51.100.128) has the longest match with the IP pattern of
vs1. If a destination IP address matches two or more virtual servers to the same extent, the request
is processed by the virtual server whose port number matches the port number in the request.
ipmask:
description:
- >-
IP mask, in dotted decimal notation, for the IP Pattern parameter. Can have leading or trailing
non-zero octets (for example, C(255.255.240.0) or C(0.0.255.255)). Accordingly, the mask specifies whether
the first n bits or the last n bits of the destination IP address in a client request are to be
matched with the corresponding bits in the IP pattern. The former is called a forward mask. The
latter is called a reverse mask.
port:
description:
- "Port number for the virtual server."
- "Range C(1) - C(65535)"
- "* in CLI is represented as C(65535) in NITRO API"
range:
description:
- >-
Number of IP addresses that the appliance must generate and assign to the virtual server. The virtual
server then functions as a network virtual server, accepting traffic on any of the generated IP
addresses. The IP addresses are generated automatically, as follows:
- >-
* For a range of n, the last octet of the address specified by the IP Address parameter increments
n-1 times.
- "* If the last octet exceeds 255, it rolls over to 0 and the third octet increments by 1."
- >-
Note: The Range parameter assigns multiple IP addresses to one virtual server. To generate an array
of virtual servers, each of which owns only one IP address, use brackets in the IP Address and Name
parameters to specify the range. For example:
- "add lb vserver my_vserver[1-3] HTTP 192.0.2.[1-3] 80."

which the request must be forwarded. This persistence type requires a rule to identify the server ID
in the request.

Also available are a number of hashing methods, in which the appliance extracts a predetermined
portion of the request, creates a hash of the portion, and then checks whether any previous requests
had the same hash value. If it finds a match, it forwards the request to the service that served
those previous requests. Following are the hashing methods:
- "* C(URLHASH) - Create a hash of the request URL (or part of the URL)."
- >-
* C(DOMAINHASH) - Create a hash of the domain name in the request (or part of the domain name). The
domain name is taken from either the URL or the Host header. If the domain name appears in both
locations, the URL is preferred. If the request does not contain a domain name, the load balancing
method defaults to C(LEASTCONNECTION).
- "* C(DESTINATIONIPHASH) - Create a hash of the destination IP address in the IP header."
- "* C(SOURCEIPHASH) - Create a hash of the source IP address in the IP header."
