Hello, I'm trying to make QoS work on a NX3064. I'm not able to make it work in the simpliest lab ever... Can anybody tell me what's wrong ?
I need to prioritize DSCP EF marked trafic from host B to host A. Host B (192.168.41.2) <-> NX eth1/48 vlan 41 Host A (192.168.41.1) <-> NX eth1/24 vlan 41 Host B is 1Gb/s Host A is 100Mb/s show run : class-map type qos match-all qos-match-prio match dscp 46 class-map type queuing qos-queue-prio match qos-group 1 policy-map type qos qos-match-trafic class qos-match-prio set qos-group 1 class class-default policy-map type queuing qos-queue-trafic class type queuing qos-queue-prio priority class type queuing class-default shape kbps 50000 interface Ethernet1/24 switchport mode trunk switchport trunk allowed vlan 41 speed 100 duplex full bandwidth 100000 service-policy type queuing output qos-queue-trafic interface Ethernet1/48 switchport mode trunk switchport trunk allowed vlan 41 service-policy type qos input qos-match-trafic Using iperf from host B to host A (udp, bandwidth = 110Mb/s), I get 50 mb/s of trafic on host A. Normal. Trying to ping from host B to host A : ping -Q 0xB8 192.168.41.1 : about 50% loss. Here's my problem. show policy-map on ingress interface show that my icmp trafic is classified and attached to qos-group 1 : N3K-eqx-pa3-1# show policy-map interface ethernet 1/48 type qos Global statistics status : enabled Global QoS policy statistics status : enabled Ethernet1/48 Service-policy (qos) input: qos-match-trafic SNMP Policy Index: 285213088 Class-map (qos): qos-match-prio (match-all) Slot 1 6845 packets Aggregate forwarded : 6845 packets Match: dscp 46 set qos-group 1 Class-map (qos): class-default (match-any) Slot 1 12776799 packets Aggregate forwarded : 12776799 packets Match: any 12776799 packets set qos-group 0 N3K-eqx-pa3-1# show policy-map interface ethernet 1/24 type queuing Global statistics status : enabled Global QoS policy statistics status : enabled Ethernet1/24 Service-policy (queuing) input: default-in-policy SNMP Policy Index: 301990027 Class-map (queuing): class-default (match-any) bandwidth percent 100 queue dropped pkts : 0 queue depth in bytes : 0 Service-policy (queuing) output: qos-queue-trafic SNMP Policy Index: 301990282 Class-map (queuing): qos-queue-prio (match-any) priority level 1 queue dropped pkts : 0 queue depth in bytes : 0 Class-map (queuing): class-default (match-any) bandwidth percent 100 shape kbps 50000 min 0 queue dropped pkts : 0 queue depth in bytes : 0 I don't see any stats here ... Thanks for your help.
