Interface utilization on some interfaces (No Rx Over) (Recommendation)

Chinmaya_Naik — Tue, 09 Feb 2021 06:38:38 GMT

Hi Team,

We come across to know that one interface is highly utilized.

Setup: 21400 Appliance with SAM Hardware (R80.10 OS)

4 SND and 8 Fw worker

Only FW , Identity Awareness and Monitor Blade Enable.

INTERFACE : 10G

Interface 10G

Utilization taken from CPVIEW (eth1-01 utilized more)

eth1-01 interface highly utiized

NO RX Over

We can see the interface is highly utilized but NO Rx Over .

Kindly suggested a solution for this

Regards

Please provide the output of ethtool -S eth1-01 for further analysis.

That interface seems to be handling the load just fine with negligible RX-DRPs and no other errors, what is your specific concern?

Is that eth1-01 interface part of a bond and the traffic is not being distributed evenly between the physical interfaces of that bond of which eth1-01 is a part? Can't really tell from what you have provided so far.

Slight tangent here but which Jumbo version is installed and what are your acceleration stats like?

Note with R80.20 and above SAM cards are disabled and R80.10 will reach end of support in May 2021.
