Nexus 7000 (NX-M132XP-12L) and QoS statistics

kremeznoy

Hi!

I have such input data:

2xN7K-C7010 - Nexus7000 C7010 (10 Slot) Chassis

2xN7K-M132XP-12 - 32x10Gbps

NX-OS version 6.1(1)

I have enable (by default) QoS feature on them:

N7k# show policy-map interface brief

Interface/VLAN [Status]:INP QOS       OUT QOS       INP QUE       OUT QUE

================================================================================

port-channel1   [Active]:                            default-in-po default-out-p

port-channel2   [Active]:                            default-in-po default-out-p

port-channel10  [Active]:                            default-in-po default-out-p

Ethernet1/1     [Active]:                            default-in-po default-out-p

Ethernet1/3     [Active]:                            default-in-po default-out-p

Ethernet1/4     [Active]:                            default-in-po default-out-p

Ethernet1/5     [Active]:                            default-in-po default-out-p

Ethernet1/7     [Active]:                            default-in-po default-out-p

Ethernet1/8     [Active]:                            default-in-po default-out-p

Ethernet1/19    [Active]:                            default-in-po default-out-p

and so on.

But I couln't see any QoS statistics on both Nexus devices:

N7k#

Global statistics status :   enabled

      queue-limit percent 82

      bandwidth remaining percent 25

      queue dropped pkts : 0

Does anybody know why?

Good day.

How much traffic are you pushing through the interface?

Hi!

Now only OSPF is working through this interfaces - 6 point-to-point relationships. And also I initiate icmp-traffic functioning by using "ping"-command.

I think that I have to see some counter increasing by using command "show policy-map interface" like in this document:

http://www.cisco.com/en/US/docs/switches/datacenter/sw/5_x/nx-os/qos/configuration/guide/statistics.html

Good day.

I read somewhere the M1 cards do not show any statistics, so the command "qos statistics" is quite useless.
