Hi All, We are planning to setup a system that would send out alerts/emails/pages whenever there are high no of collisions on a network segment or we have reached threshold traffic. We need something that can alert us on a pro active-basis and not after the actual problem has occurred, before the whole network is down. We have multiple Catalyst 6509's switches and a few routers. We are using Cisco Works 2000 to manage the switches. I would appreciate any help. Please let me know what tool can be used to achieve what we need. Thanks Raminder Chhatwal
