[c-nsp] 6500 Netflow

[Paul Stewart]

Thanks Jared... I get the following:

dis2-swt-to#show mls netflow table-contention summary
Earl in Module 1
Netflow Entry Creation is Enabled. Maximum number of flows is 128K
Summary of Table Contention Levels (on a scale of 0 (lowest) to 5 (highest))
============================================================================
L3 Contention Level: 0

The contention level floats between 0 and 1.... have a few other suggestions
from the list to try as well...

Thanks ;)

Paul

	the tcam size is tiny and you're likely overunning it.

	check:

show mls netflow table-contention summary

	Watch your 'Netflow Creation Failures' increase.
