Intel XL710 for 40GbE SRIOV: Checking network rx/tx count for each VF

Intel XL710 for 40GbE SRIOV: Checking network rx/tx count for each VF

Hello.

 

These are the 40GB NIC cards on the host machine:

# lspci -nn | grep Ethernet

b0:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ [8086:1583] (rev 02)
b0:00.1 Ethernet controller [0200]: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ [8086:1583] (rev 02)

 

One Physical Function per XL710 40 Gigabit Ethernet Controller NIC port and 30 Virtual Functions assigned to each physical function.

[root@com5 ~]# cat /sys/class/net/ens1f0/device/sriov_numvfs
30
[root@com5 ~]# cat /sys/class/net/ens1f1/device/sriov_numvfs
30

 

For the PF, I can check Rx/Tx packet counts and bytes by using "ifconfig" command.

[root@com5 ~]# ifconfig ens1f0
ens1f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 fe80::4adf:37ff:fe42:1450  prefixlen 64  scopeid 0x20<link>
        ether 48:df:37:42:14:50  txqueuelen 1000  (Ethernet)
        RX packets 392099  bytes 34188783 (32.6 MiB)
        RX errors 0  dropped 1470  overruns 0  frame 0
        TX packets 28744  bytes 12584185 (12.0 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
 

But is there any way to get Rx/Tx packets and bytes information for the each VF?

 

Please let me know.

Thanks.

 

Regards,

For more complete information about compiler optimizations, see our Optimization Notice.

Never heard of that, you should consult the tech support, to have better insight for your query. While, if you wish to have successful career in IT Sector, you must train yourself to gain the Cisco Certification.

The best CCIE Routing and Switching Lab Crams would be provided by many institutions, but for me, the best one would be the SPOTO CCIE Club, they have the best CCIE LAB Dumps, which are cheap as well as totally reliable.

Could you tell me how can i get more help related to Intel XL710 for 40GbE SRIOV
