more than likely, when the switch was initially imported, the snmp-poll 
at the time, detected the port as having a 1gb optic, and set it to 
that.

so, especially, if you’ve swapped optics, or the port physical state 
is now 10gb/s you’ll need to snmp-poll the switch again.
you can confirm by looking at the MAU port info:  switches/choose 
$switch/view port mau detail (database only) and see if that matches 
what you expect.
if it shows the legacy port size, you can re-poll the switch, and 
regenerate the mrtg config file.
