Hi Krishnan, sho int fa3/0/0 rate-limit wd give you better info. could you provide that? -----Original Message----- From: Sivaramakrishna Iyer Krishnan <krishnan@research.bell-labs.com> To: raszuk@cisco.com <raszuk@cisco.com> Cc: MPLS Operations <mpls-ops@mplsrc.com>; Alexander Marhold <alexander@marhold.at> Date: Thursday, July 26, 2001 1:01 PM Subject: tunnel stats (totally confusing) !!! > >Hi Robert, > >I changed the CAR to act on the Fast ethernet instead of the tunnel.
