create slb pool <poolname> {slb-method
[round-robin | ratio | priority | least-connections]}
Creates a server pool and optionally
assigns a load-balancing method to the
pool. The default load-balance method is
round-robin. A pool represents a group of
physical servers that is used to
load-balance one or more VIPs.

addresses (VIPs) and attaches the VIP to a
pool of physical servers. The server pool
needs to be created before the VIP is
created. If the port parameter is not
specified, all requests to the VIP are

parameter is specified, only the specified

server. All other packets are dropped.
