Maybe the switch has negotiated the port speed to 100 Mbps.

The ports are gigabits.

Post the complete output to the command "sh interface <PORTS>". 

I want to see the output of the WAN port as well as the port used to perform the speed tests.

Hello,

post the output of:

show interfaces x

where 'x' is the interface of your 3850 that has the speed issue...

Possibly like Georg and Leo, since you describe obtaining 100 Mbps, I too would look for a port or ports running at 100.  Notice my mention of "port or ports".  I.e. you need to check all ports from device performing speed test to/from ISP.

Besides port speed, check your cable. Make sure it is CAT 5e or better yet Cat6 as all 8 pair of wires must be active to move at 1 Gig speed of data.

Dear Martin,
The same cable when I am connecting to my laptop is getting 200 mbps.

What "attachment"?

hi,

is the ISP hand off an ethernet/RJ45 cable?

try to bypass your sophos FW by connecting directly a laptop to ISP cable, manually set public IP and perform an FTP or iperf test.

Dear Sir,
I checked the speed from the ISP modem directly 200 mbps and after
connecting the firewall i am getting the same speed 200 mbps.
Thanks.
