I have several Catalyst 6500 (Supervisor 32) aggregation switches with WS-X6148A-GE-TX and WS-X6148-GE-TX line cards.
These line cards do not support storm-control/broadcast suppression. This impacted us badly during a recent spanning tree event.
As it stands, we are at risk of overwhelming control planes with excess broadcast or multicast traffic, and I need to find alternative ways to protect these switches.
I have been researching STP enhancements, and control-plane policing in the folowing documents, and would appreciate advice from engineers who may have had to implement similar workarounds for storm-control in a service provider setting.
