Dear Colleagues,
I am stuck in trying to solve a TCAM/Netflow table utilization problem on 7606. I get sometimes (not the peak hours, it can happen when I have least traffic or pps) the following messages:
MET_DST: %EARL-SP-4-NF_USAGE: Current Netflow Table Utilization is 99%
the otput of "#sh mls netflow table-contention detailed" :
Earl in Module 5
Detailed Netflow CAM (TCAM and ICAM) Utilization
================================================
TCAM Utilization : 100%
ICAM Utilization : 0%
Netflow TCAM count : 262016
Netflow ICAM count : 0
Netflow Creation Failures : 2658971
Netflow CAM aliases : 0
I have the following MLS Netflow config:
mls flow ip destination-source
mls sampling time-based 64
no mls acl tcam share-global
ip flow-aggregation cache prefix
cache entries 524288
cache timeout inactive 60
mask source minimum 32
mask destination minimum 32
enabled
When I see the netflow database on the collector, it shows me pretty normal for this hour number of conversations (for 5 minutes, not exceeding 40000).
When I do "sh mls netflow ip", I get up to 30k entries. IPv6 gives me less than a thousand.

What could the problem be?
