IIRC you are just meant to get the normal "0.0.0.0/0 drop" entry changed to "0.0.0.0/0 punt" to get everything that hasn't made it into the TCAM to be punted to the MSFC for processing. Or at least that's what TAC said. This didn't help/work when we had a 0.0.0.0/0 route BEFORE the drop one. > Chris Griffin wrote: > > Is there a way to determine *which* entries are software switched when a > > Sup720 exceeds FIB TCAM?

For a given prefix it's easy enough to compare "show ip cef" to "show mls cef". Other than that, I had to dump the entire outputs and script comparing them. With the outputs of show ip cef and show mls cef each in a file I did this to compare number of prefixes... for i in `seq 1 24` do FIB=`fgrep "/$i " $FIBFILE | wc -l` RIB=`fgrep "/$i " $RIBFILE \ | fgrep -v "127.0.0.0/8" \ | fgrep -v "224.0.0.0/4" \ | wc -l` echo "Number of /$i in RIB: $RIB FIB: $FIB" done Easy enough to find which from $RIBFILE are not in $FIBFILE and "clear ip route" if you find ones your trying to force back into the TCAM. -- Euan Galloway _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
