Hi All,

 

Recently I changed some mls aging timers to a fairly aggressive (low)
setting to fix a TCAM threshold issue we were hitting which was breaking
netflow creation/export.

 

I understand the different timers and how they affect the length of time a
flow will stay in TCAM but i'm curious as to the possible negative side
affects caused by having low timers with netflow(or anything else for that
matter)?

 

Would it just result in more flows being generated?

 

This is what i'm currently running:

 

mls aging fast time 5 threshold 32

mls aging long 300

mls aging normal 60

 

TCAM utilization is sitting nice at around 10-20% with these values, default
had it hitting upwards of 90%+

 

Cheers

 

Ben
