Hi James,
You can either rate limit on per Vserver basis or rserver basis.
example1: rserver based rate limiting
serverfarm host cisco-farm
rserver cisco-server
rate-limit connection 300
example2: Vserver based rate limiting
parameter-map type connection syed-map
rate-limit connection 300
policy-map multi-match vlanx-vips
class VIP80
connection advanced-options cisco-map
Rate limiting based on any other source or destination criteria is not supported.
One option to explore would be to use a dedicate context for a particular APP and
resource limit the connections using "limit-resource rate" command.
CiscoACE1/Admin(config-resource)# limit-resource rate ?
bandwidth Limit bandwidth in bytes per second
connections Limit connections per second
inspect-conn Limit rtsp/ftp inspect connections per second
mac-miss Limit mac miss traffic (punted to-the-box) in pkts/sec
mgmt-traffic Limit management traffic (to-the-box) in bytes per second
ssl-connections Limit number of SSL connections per second
syslog Limit syslog messages per second
I hope both of the following 2 URLs will answer most of your queries:
