[c-nsp] Crazy control-plane CoPP counters?

[Robert Williams]

Hi,

Yup - unfortunately that command doesn’t seem to be present on 15.1(1)SY or 12.2(33)SXJ

Cheers!

clear control-plane *

Works for me, but I presume you have already tried this.

(WS-C6509-E) - 122-33.SRE3

   Supervisor Engine 720 (Active)         WS-SUP720-3BXL
   Supervisor Engine 720 (Hot)            WS-SUP720-3BXL
