Hi,
I have a question related to the SAP MTU.
We are using the 8.9.0.2 version and the command "show ap debug received-config ap-name XXX" show us :
SAP MTU 10 bytes
RAP MTU 1300 bytes
I've check the AP-System Profile and nothing is set in the SAP MTU field (means auto-negociation)
As we have some performance issue, i'm asking if this is normal to get a SAP MTU of 10bytes ? If i'm downgrading to 8.8.0.3 the SAP MTU is 1500 bytes.
Thanks in advance.
Regards.

Check this part of the documentation:
|
SAP MTU
|
MTU, in bytes, on the wired link for the AP. The supported range is 1024-1578 bytes.
|
|
RAP MTU
|
Configures the maximum size of the GRE packets exchanged between a RAP and the controller. The supported range is 1024-1578 bytes and the default value is 1200 bytes.
|
So SAP MTU is for the wired port, the RAP MTU for the GRE tunnel MTU.

Is RAP for Remote Access Point and SAP for CAP?
