e. (Optional) Assign a unique identifier for DFP:
f.
Specify one or more real servers in the server farm.
2.
a. Identify the real server:
b. (Optional) Specify a connection threshold.
c. (Optional) Assign a relative capacity weight:
Enable client NAT with a pool:
■
(server-farm) nat client pool-name
The SLB NAT pool is identified by pool-name (up to 15 characters).
(server-farm) bindid [bind-id]
Sometimes, a real server is assigned to multiple server farms. The bind-id (0 to
65533; default 0) is an arbitrary identification value given to a server farm. Each
instance of a real server references this value, allowing DFP to assign a unique
weight to it.
(Optional) Test the server with a probe:
(server-farm) probe name
The probe defined as name (text string, up to 15 characters) periodically tests for
server connectivity and operation. IOS SLB offers ping, HTTP, and Wireless
Session Protocol (WSP) probes. The CSM also offers TCP, FTP, SMTP, Telnet,
and DNS probes. See section "10-3: SLB Probes" for more information about
configuring probes.
(server-farm) real ip-address
The real server has the IP address given by ip-address.
■ Set the maximum number of connections:
(real-server) maxconns number
At any given time, the real server will be limited to number (1 to 4,294,967,295
connections; default 4,294,967,295) active connections.
(real-server) weight weighting-value
The real server is assigned a weighting-value (1 to 255; default 8) that indicates
its capacity relative to other real servers in the server farm. For weighted round-
robin, weighting-value defines the number of consecutive connections the serv-
er receives before SLB moves to the next server. For weighted least connections,
the next connection is given to the server whose number of active connections is
furthest below its capacity. The capacity is computed as the weighting-value
divided by the sum of all real server weighting values in the server farm.
