# A policy consists of a series of conditions, plus the actions to take if those
# conditions are matched. In this case, the only condition is client-group 50 which
# requires the incoming connection to match the standard access-list 50. The only action
# to take is to use server farm WEBFARM2 to serve those requests.

slb-policy SOURCE-IP-50
# Slb-policies associated to a virtual server are always examined in the order in which
# they are configured. The defintion of the server farm under the virtual server
# configuration is the default policy and is always used as a last resort if no policy
# matches, or if there are no policies configured.
# In this case, incoming requests are processed to see if they match the conditions of the
# slb-policy SOURCe-IP-50. If they do, then the server farm WEBFARM2 is used, otherwise
# the default policy is selected (for example, WEBFARM is used).
# If a default server farm is not configured, then connections that do not match any
# policy are dropped.
# This example shows how to configure the IOS standard access list. You can configure any
# of the 1-99 standard access lists, or you can configure named access lists
