I am experiencing issues when querying bandwidth stats on the spf1 interface if a CCR-1036-12G-4S running v6.2 of the OS. I am not sure if this applies to all interfaces or only the spf interface.
When the interface has traffic exceeding 100mbps it truncates the speed. Example: when the router is receiving 140mbps on the spf interface my snmp query is reporting 40mbps. I am using the ifInOctets (188.8.131.52.184.108.40.206.1.10) and ifOutOctets (220.127.116.11.18.104.22.168.1.16) for my queries and a multiplier of 8 to get to bits.
Has anyone else experienced this issue? I have seen others post where they have CPU issues relating to having SNMP enabled, but I have not seen what I am describing. I have sent in a trouble ticket with MikroTik but have yet to hear back from them.
