[f-nsp] Problem with dynamic cam-mode on netiron mlx 5.3.00d: "Warning: IPv4 Route ADD: CAM entry creation FAILED"

[Gunther Stammwitz]

Dear colleagues,

 

has someone else seen problems with dynamic cam mode on the netiron mlx?
I have upgraded the system to 5.3.00d and switched from static to dynamic
cam mode at the same time.

 

>From time to time I can see the following WARNING in the system log:
"Warning: IPv4 Route ADD: CAM entry creation FAILED".
Does anyone know why this is happening and if the router tries to program
the problematic entry into the cam again or is it getting lost?

 

Has anyone else seen these problems before - if so: which version are you
running?

Is anyone running dynamic cam-mode without problems? If so: which version is
running fine?



This router is running bgp4 with full tables and two feeds and pushes about
3 gigabit per second on a NI-MLX-1Gx20-SFP-linecard in slot1.
