  • Cisco 3600 Series Multiservice Platforms

Known Affected Releases

12.2(12.2)T1

Description (partial)

Symptom:

The symptom is the appearance of the <CmdBold>IPFAST-PAKSTICK <NoCmdBold> message
pretty much every minute depending on the traffic being forwarded.

Conditions:

The error message appears usually on cisco 4500 or lower end platforms (but could,
on occasion happen on the 7200 or 7500 too depending on configuration).

There are a variety of scenarios that could lead to this error message and all of
them involve multiple invocations of the ip forwarding code. For e.g.

- an MPLS packet coming in a GRE tunnel and being switched out using deaggregation
  or going out a GRE/IPSEC tunnel.
