Hi Zach,
Thanks for your replay. IOS-XE 03.08.04E sup engine Sup 8-E . No option for entering  ip mfib fastdrop, all I get is ip mfib carriage return.
Are you sure this chassis is EoS? I thought it was quite new.

Harry,

What Supervisor engine are you running, and what IOS/IOS-XE version? Also, what error are you getting when you enter "ip mfib fastdrop"?

I don't know how much luck you're going to have with TAC, that chassis has been EoS since April of this year.

Thanks,

Hi All,
Trying to add the command:
 IP mfib  fastdrop  to a  WS-C4510R+E 10 slot switch, this is to protect the CPU from non-RPF traffic, ie traffic that fails RFF checks. This command did work on older chassis, before I open a Tac case for this has anyone else experienced this issue?. Thanks in advance.
