I have deployed IWAN solution with cisco 892FSP Branch routers (IOS version is 15.7(3)M1).
I get the following error message :
May 8 2018 08:00:00.071 CEST: %MMA-3-CACHE_OVERFLOW: The number of flows has exceeded 95% of the configured size, monitor MON-Egress-aggregate-0-0-5, please increase cache size
I agree with the increase of the cache size. However I don't know how to do that and what is the best practice value for this kind of routers.
Do you have any ideas ?
Many thanks in advance.
Solved! Go to Solution.
I am getting this error on one of my HUB routers. When I go to enter the command:
monitor-cache-percent ? ! it tells me
<1-100> cache usage (%), border instance will AUTOMATICALLY go through SHUT/NO SHUT any ACTIVE traffic on this border will be affected
May I ask:
1. Is this going to reset all ACTIVE traffic going through this router?
2. Is this reducing the threshold for what is being monitored? I thought I would want to increase a queue size...
Thank you for any insight you might be able to provide.
