I have been trying to see if there is a way to set the default tunnel bandwidth to something other than 0.1. Most of ours need be set to 100 instead of .1 and until set throw our numbers out of whack.
Is this possible??
are you saying that if there is a possible way to set the bandwidth of an interface on NPM to a value of 0.1?
Ice, what we are finding is that when I check the bandwidth setting for a Cisco tunnel it is set to 0.1 by default. I am not sure how this gets set. We have to go back in and tweak it to 100 and then we get proper readings.
go to the interface details page for that interface - Edit Interface
tick Custom bandwidth set the TX and RX to 100 MB
save the settings
Thanks Ice, that is what we have been doing but I want to know if it is possible to have a default setting rather than having to click through each individual one. One a t a time is a pain.
NPM uses RFC1213 and for Interface OID, it uses the following:

Free RFC1213-MIB SNMP MIB Download - Free MIB Download - Search MIBs - OiDViEW
whatever you have default speed set on the interface/port of your device/node, it will reflect on the SNMP of your device and node. NPM will throw this OID to check what is your interface speed for this interface - and your device will return it.
now that will be the value it will use for your Interface % utilization. TX/RX / Interface bandwidth x100%
so if you have not change it on your device let say your WAN interface, there is an option on NPM you can set it to custom bandwidth. now if you do not want to that - even if you have not yet added it on NPM, or you do not have any monitoring, it will be a best practice to change the interface speed of a link if you are referencing to a speed/bandwidth like your ISP.
