Cisco supports a 'bandwidth' command for interfaces which lets you set the bandwidth SNMP value. This is only used for SNMP and is used to configure a threshold for SNMP monitoring systems so that they know what value constitutes a maximum threshold for traffic, and they will send alerts when this threshold is crossed.
It is a problem especially with Tunnel interfaces that there is no equivalent to this bandwidth command. Instead MikroTik always reports 10Mbps is the maximum. This means that any tunnel exceeding 10Mbps usage will trigger an alert in network monitoring systems.
Please either implement this bandwidth command to allow setting the SNMP reported bandwidth value, OR increase the bandwidth reported by the tunnel to something much higher than 10Mbps.
I would think this would be a fairly simple request to implement, since it only impacts SNMP reporting and the bandwidth setting has no other purpose.
