WCCP redirected packets counter not incrementing for my WCCP service group
WCCP redirection appears to be working normally, but the "show ip wccp detail" command shows that zero packets have been redirected.
The "Packets redirected" counter in the "show ip wccp <service_group> detail" output only increments whenever a packet is redirected via CPU switching. Whenever CEF is being used with inbound WCCP redirection, L2 forwarding method, and mask assignment, all WCCP traffic should be redirected via hardware and the counters will not increment.
Packet redirection done via CPU switching can result in excessive CPU utilization and is more expensive than CEF. If WCCP redirection is working properly and CEF is being used, then WCCP is running optimally and the packet redirected counter will not increment.
