Monitor interface IPv6 traffic

[Yvan.hua]

I encountered a problem when using ZABBIX to monitor IPv6 traffic. The details are as follows:

1. IPv4 address and IPv6 address are configured on the interface.
2. Use ZABBIX monitoring equipment
3. IPv4 use oid: 1.3.6.1.2.1.31.1.1.1.6 And 1.3.6.1.2.1.31.1.1.1.10. It can work normally
4. IPv6 uses oid: 1.3.6.1.2.1.4.31.3.1.6.2 and 1.3.6.1.2.4.31.3.1.33.2. Traffic can be monitored, but the data is very small. I guess the number of packets may be monitored, not the rate
6. Equipment information: ws-c3850, cat3k_ CAA-UNIVERSALK9
Do you know the oid that monitors IPv6 interface traffic?

Hi

 But if you want to monitor traffic in IPV6, this suppose you have application talking end to end using IPv6. Is it your scenario? Cause in real world, I think IPv6 basically us used to routing but end user traffic goes to IPv4.  Not sure, of course, how is your setup.

 One interesting point is that another day my home router stop assigning IPv4 address and started assign only IPv6 and most sites I used to access stop working as they does not accept pure IPv6 on the application.

vm---sw----gw---isp

All nodes in my network have IPv6 public network addresses
During the test, I configured the IPv6 and IPv4 addresses of the public network on the VM (Windows), and then I sent 20m / s traffic to the VM through iperf at home. However, through ZABBIX observation, the data was only dozens of B, so I suspected that the OID I was looking for was wrong.

Hi,

1.3.6.1.2.1.31.1.1.1.6 (ifHCInOctets) and 1.3.6.1.2.1.31.1.1.1.10 (ifHCOutOctets) do not count IPv4 packets only, they count all packets on the interface (IPv4, IPv6 and maybe other protocols).

You might use 1.3.6.1.2.1.4.31.3.1.6.1 (ipIfStatsHCInOctets.ipv4) and .1.3.6.1.2.1.4.31.3.1.6.2 ipIfStatsHCInOctets.ipv6 for incoming and

1.3.6.1.2.1.4.31.3.1.33.1 (ipIfStatsHCOutOctets.ipv4) and .1.3.6.1.2.1.4.31.3.1.33.2 ipIfStatsHCOutOctets.ipv6 .

Unfortunately old IOS devices do not support the IPv4 counters. IOS, IOS-XR and NX-OS only count CPU switched packets. ASA and AireOS don't support these OIDs at all. IOS-XE seems to work correctly.
