We're building an internal network monitoring tool and we've been asked to include bandwidth metrics for inbound and outbound. According to the Cisco document on how to do this (https://www.cisco.com/c/en/us/support/docs/ip/simple-network-management-protocol-snmp/8141-calculate-bandwidth-snmp.html) we've done everything right when it comes to the calculation and we've switched to using the 64-bit OIDs rather than the 32-bit ones (as it's a Gigabit device) but while the inbound one looks reasonable (bounces around at about 1 to 2 Mbps/sec) the outbound values look totally wrong (as in 1,000,000 to 2,000,000 Mbps/sec).
We're happily talking to the AXA 5506 over SNMP, getting values back etc. but I don't know whether the problem is something to do with the calculation or something to do with the way that the network is setup (this box sits inside a third-party data centre - i.e. could it be that it's picking up traffic from the entire data centre?)
The OIDs we're querying are 184.108.40.206.220.127.116.11.1.5.2 (for the interface speed), 18.104.22.168.22.214.171.124.126.96.36.199 (for the Outbound octet count) and 188.8.131.52.184.108.40.206.220.127.116.11 (for the Inbound octet count) and all are returning values (*big* values in the case of the Outbound count).

What is Network Emulation?
Network emulation is one of the key elements of effective network testing, helping you find problems in-house instead of customer environments. To create such test environments, it would require either physical hardware or ...
If you are a cisco employee, u can test the code using ASR9K devices in lab. I did test on 172.18.87.36 (be connected to cisco vpn).
The use case of the code is that, customer has to everytime manually upload logs and files in SR which are shared by TAC o...
