We have one catalyst 4948.we have create 3 vlans on this catalyst. each vlan has 3 servers. we want to load balance the traffic among the servers on the same vlan. We want to connect one css11503 in one arm mode. can we create a trunk link between the catalyst and the CSS to load balance the traffic to all the servers on the same vlan, so we can have load balancing for all vlans at the same time without change the topology of the network?
