I've got an ASA (v9.5) with an external interface that is a 1GB connection. But we only have 100mb provisioned from our ISP. So our max utilization would be 100mb/s.
When we poll the router in SNMP tools, it reports the percent utilization based on 1gb/s.
Is there a way to tell the ASA that the interface is 100mb/s bandwidth?
For example on a Cisco router, we would use the statement bandwidth 1000000 to set the speed for SNMP report. But that command doesn't exist on the ASA
Since you only have 100Mbit/sec provisioned you may change the interface speed between your asa and router to 100 Mbit using the speed command in the interface configuration.
SNMP will correctly report the speed in the ifspeed MIB then. (.126.96.36.199.188.8.131.52.1.5). If that is not an option for you, you should adapt your reporting tool to handle this issue.
We use Solarwinds to monitor. This gives us the ability to set a custom bandwidth for an interface. Once the device is properly discovered you can edit the interface and set a custom bandwidth to 100Mbs.
