Today, while reviewing the export backup, I noticed that the following line appears in the cAPax export:
/interface ethernet switch set 0 cpu-flow-control=yes
On the RB5009 (where it is also enabled), this line does not appear in the export. Does this mean that this setting is the default on the RB5009 but not on the cAPax?
On my wAPax, /interface ethernet switch is completely empty – is that normal?
Best regards, Richard
Was the export backup made long ago? The wAP ax has no switch chip, and the switch chip inside the cAP ax (which is classified as IPQ-PPE in RouterOS) has no support for hardware offload at the moment and has no ability to change the cpu-flow-control at all. See:
Switch Chip Features | RouterOS Manual
Since RouterOS v6.43, it is possible to disable the CPU Flow Control feature on some devices that are using one of the following switch chips: QCA8337, Atheros8227, Atheros8327, Atheros7240, Atheros8316, 88E6191X and 88E6393X. Other switch chips have this feature enabled by default and cannot be changed.
On devices where the setting can be changed, like on the RB5009, which has the 88E6393X switch chip, the default value is yes.
From 7.20+ you should probably no longer see the parameter in the export of the cAP ax:
But I don't have the device to verify that.
I have set it explicitly to yes on my RB5009 and it is not shown on the export.
Yes, as I wrote above it's the default for the RB5009, and as a result it doesn't show up on /export. But OP wrote about the entry for the cAP ax. That must be from an older export output because with newer RouterOS the parameter should no longer be there for the cAP ax (but I don't have this device).
Just checked on a cAP AX, when set (either yes or no) it is visible in the export. When unsetting, it is not shown in the export (obviously). Which makes me think there is no default value.
