Can someone provide a link, or more detail, on the netflow issues. Particularly as they relate to 6509's and sup720's. Thanks! On 7/18/09, Roland Dobbins <rdobbins () arbor net> wrote:

This is a major problem in many cases. The NetFlow issues render flow telemetry unusable in production situations. The ACLs work very differently on this platform due to LOU issues, as you say. Most folks don't know this, and many end up overflowing their TCAMs and not realizing it until their boxes fall over, heh. If one has fairly complex ACLs covering various ranges of ports, ACLs on 7600/6500 quickly become very difficult to manage.EARL8 (Nexus7k) fixes the IPv6/uRPF and IPv6/ACL issue.And the NetFlow issues. ----------------------------------------------------------------------- Roland Dobbins <rdobbins () arbor net> // <http://www.arbornetworks.com> Unfortunately, inefficiency scales really well. -- Kevin Lawton
