On a SUP7203BXL, if your ACL TCAM utilization is fine, this shouldn't impact performance unless you're logging too much. Since you've been over the CPU utilization doc, I'm guessing you know that. "show platform hardware capacity acl" will give you a breakdown on your ACL TCAM usage. > I'm probably missing some other key details, but what could influence > the SP like this? Any insight would be appreciated. Cisco says that Netflow-based features always handle the first packet of a flow in software, but I don't know if this is the RP or the SP. It would make sense if a first-flow packet that didn't need punting hit the SP and not the RP. In that case, your traffic level with netflow enabled could explain your high SP utilization. -- Ross Vandegrift [email protected] "If the fight gets hot, the songs get hotter.
