Can anyone advise the best way to allow non-load-balanced IP traffic through a Cisco ACE? The ACE must load-balance for some traffic but act as a router for all other traffic.
As long as you have the access-list and routing configured, the ACE should be able to forward the traffic at L3 without load balancing.
The traffic is load balanced when you have the traffic hitting a VIP with service policy applied on an interface.
Ok, thanks that was my general understanding too, just hoped there would be no need for any fancy class-maps etc. Thanks very much
Also here is an example where you still have the traffic hitting a VIP and dont want to load balance
Configure a class map for HTTP traffic . Then configure the ACE to forward requests that match a http policy map
without performing loadbalancing on the request -- use the forward command in load-balancing policy-map class configuration mode.
class-map match-all HTTP_CLASS
2 match virtual-address 184.108.40.206 tcp eq 80
switch/Admin(config-pmap-c)# policy-map type loadbalance first-match
switch/Admin(config-pmap-lb)# class class-default
policy-map multi-match SMTP
loadbalance policy http-forwarding-lb-pm
Hope this helps.
