SSG140 Interface 0/9 traffic Bandwidth issue

Hi,

I 'm try to connect a 500mb internet link to replace current 100mb link. 

When I check the interface bandwidth report and it's still showing Ethernet 0/9 100Mbps as snapshot attached. 

However, when I tried to modify the traffic bandwidth under the interface 0/9, it doesn't allow me to setup Egress or Ingress over 100000 Kbps. I believe Ethernet port 0/8 and 0/9 are gigabit port. 

The system is currently running screenOS 6.1 or 1.0. Any help or advice will be appreciated.

Thanks,

Felix
