ethtool -g Exp1-1 10Gig interface

[cciesec2006]

From what I can tell, the 10Gig interface on checkpoint appliance can support up to 4096 RX and TX, however, the default in Checkpoint for RX and TX is set to 512 and 1024, respectively.

What is going to happen if I set both the RX and TX to 4096? What are the Pro's and Cons for setting RX and TX value to 4096?


[Expert@Power-1-S:0]# ethtool -g Exp1-1
Ring parameters for Exp1-1:
Pre-set maximums:
RX: 4096
RX Mini: 0
RX Jumbo: 0
TX: 4096
Current hardware settings:
RX: 512
RX Mini: 0
RX Jumbo: 0
TX: 1024

Increasing ring buffer sizes is a last resort to combat excessive (IMHO >0.1%) RX-DRPs. If excessive RX-DRPs are encountered, the right way to address it is by increasing the number of SND/IRQ cores and/or enabling Multi-Queue. One can also increase the Gaia SoftIRQ "budget" but this is undocumented and unsupported by Check Point. Increasing ring buffer size is a last resort due to BufferBloat.
