Consistently see output drops on TenGig interface (actually a 1GB fiber handoff using the TenGig SFP for MPLS) on a C9300 (16.9.1).  Auto QoS applied to interface and softmax-queue is at 1200 on switch as well.  Output from sh run int x/x/x, sh int x/x/x and sh policy-map int x/x/x below.  From what I can tell, the drops are occurring in the class default queue, so CS0 traffic I believe.  We are using WebEx Room Kits (dscp AF41) that occasionally have a degradation in call quality and the ingress/egress to source/destination is via this interface.  Packet captures have shown that the traffic for the Room Kits are UDP and bursty in nature.  With the output from sh policy-map and what is reported from end users on calls, I am not seeing drops from the correct queue.  Where else can I investigate to find root cause of the total output drops on this interface?  Appreciate any thoughts and ideas.  Thank you.      interface TenGigabitEthernet1/1/1 description Link to XX circuit switchport trunk allowed vlan x,x,x switchport mode trunk switchport nonegotiate ip flow monitor xxxxxxx input ip flow monitor xxxxxxx output load-interval 30 auto qos trust dscp   #sh int te1/1/1 hum TenGigabitEthernet1/1/1 is up, line protocol is up (connected) Hardware is Ten Gigabit Ethernet, address is 6cdd.30ef.581d (bia 6cdd.30ef.581d) Description: Link to xx circuit MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec, reliability 255/255, txload 4/255, rxload 3/255 Encapsulation ARPA, loopback not set Keepalive not set Full-duplex, 1000Mb/s, link type is auto, media type is 1000BaseSX SFP input flow-control is on, output flow-control is unsupported ARP type: ARPA, ARP Timeout 04:00:00 Last input 00:00:00, output 00:00:03, output hang never Last clearing of "show interface" counters 19:47:32 Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 53478785 Queueing strategy: Class-based queueing Output queue: 0/40 (size/max) 30 second input rate 13.26 mega-bits/sec , 4.47 Kpps 30 second output rate 18.54 mega-bits/sec , 5.13 Kpps 227,392,297 packets input, 94,867,305,256 bytes, 0 no buffer Received 209,678 broadcasts (161,215 multicasts) 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 0 watchdog, 161,215 multicast, 0 pause input 0 input packets with dribble condition detected 592,500,567 packets output, 440,236,724,792 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 2,375 unknown protocol drops 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier, 0 pause output 0 output buffer failures, 0 output buffers swapped out     #sh policy-map int te1/1/1 TenGigabitEthernet1/1/1 Service-policy input: AutoQos-ppm-Trust-Dscp-Input-Policy Class-map: class-default (match-any) 245237044 packets Match: any QoS Set dscp dscp table AutoQos-4.0-Trust-Dscp-Table Service-policy output: AutoQos-ppm-Output-Policy queue stats for all priority classes: Queueing priority level 1 (total drops) 0 (bytes output) 3320094515 Class-map: AutoQos-ppm-Output-Priority-Queue (match-any) 0 packets Match: dscp cs4 (32) cs5 (40) ef (46) Match: cos 5 Priority: 30% (300000 kbps), burst bytes 7500000, Priority Level: 1 Class-map: AutoQos-ppm-Output-Control-Mgmt-Queue (match-any) 0 packets Match: dscp cs2 (16) cs3 (24) cs6 (48) cs7 (56) Match: cos 3 Queueing queue-limit dscp 16 percent 80 queue-limit dscp 24 percent 90 queue-limit dscp 48 percent 100 queue-limit dscp 56 percent 100 (total drops) 0 (bytes output) 13945849 bandwidth remaining 10% queue-buffers ratio 10 Class-map: AutoQos-ppm-Output-Multimedia-Conf-Queue (match-any) 0 packets Match: dscp af41 (34) af42 (36) af43 (38) Match: cos 4 Queueing (total drops) 0 (bytes output) 1751968690 bandwidth remaining 10% queue-buffers ratio 10 Class-map: AutoQos-ppm-Output-Trans-Data-Queue (match-any) 0 packets Match: dscp af21 (18) af22 (20) af23 (22) Match: cos 2 Queueing (total drops) 0 (bytes output) 197615796 bandwidth remaining 10% queue-buffers ratio 10 Class-map: AutoQos-ppm-Output-Bulk-Data-Queue (match-any) 0 packets Match: dscp af11 (10) af12 (12) af13 (14) Match: cos 1 Queueing (total drops) 0 (bytes output) 19404909061 bandwidth remaining 4% queue-buffers ratio 10 Class-map: AutoQos-ppm-Output-Scavenger-Queue (match-any) 0 packets Match: dscp cs1 (8) Queueing (total drops) 0 (bytes output) 0 bandwidth remaining 1% queue-buffers ratio 10 Class-map: AutoQos-ppm-Output-Multimedia-Strm-Queue (match-any) 0 packets Match: dscp af31 (26) af32 (28) af33 (30) Queueing (total drops) 0 (bytes output) 4075465486 bandwidth remaining 10% queue-buffers ratio 10 Class-map: class-default (match-any) 0 packets Match: any Queueing (total drops) 54552249 (bytes output) 415018269243 bandwidth remaining 25% queue-buffers ratio 25 ...

Recently purchased an RV345 and need to do dynamic NAT, i.e. ip nat inside and ip nat outside, pool and ACLs, etc...  Is that possible on this device?  Im reading conflicting information and all Ive seen is one to one NAT ability.  Please help.  Thank you.  ... View more
