12.0S 12.2SPI

Description (partial)

Symptoms: When you enter the <CmdBold>show cef idb<noCmdBold> EXEC command on 
a primary Route Processor (RP), the output of the command displays that for 
two subinterfaces of the same interface that should have the same interface 
number, one of the subinterfaces has a "-" sign in the "iIndex" column and 
both subinterfaces have the same number in the "fIndex" column.

Conditions: This symptom is observed on a Cisco 12000 series that is running 
Cisco IOS Release 12.0(24)S and may also occur on a Cisco 7500 series and a 
Cisco 10000 series. The symptom occurs when there are multiple subinterfaces 
on one hardware interface, when a Stateful Switchover (SSO) occurs, and when 
the original active RP (that becomes the new standby RP) reloads.
