Turn 1GBPS INTERFACE SPEED TO LAN

Question

Hi Team, 
 I've a problem and needing for resolve, 
 About my config: 
 - 3 Routers WAN with 1Gbps (connected to sophos) 
 - 1 Sophos FW XGS 2300 
 - 14 Switch ARUBA 6100 (Port in POE/1Gbps) 
 The problem is in the "PORT1 Interface SPEED LAN" => 100 Mbps. I tried to turn it on 1000Mbps and the port down, so after reboot, I got this with Physical 1000Mbps/LAN 100MBPS 
 
 But for really, the port1 LAN is 100Mbps. 
 Why the interface speed of LAN are in 100Mbps How can I solve it ?

The interface speed is fix on 1000Mbps but in really it's in 100Mbps ! 
 What is the solution ?

Hi, 
 You can not set the interface on XGS on 1000 FDX (fixed) and the switch on auto. You have to set them both on the same setting. Auto for both is the default, but you can also set them both to 1000 FDX. 
 But you have a problem (port or cable) on the switch or XGS if they can't Auto to 1000 Mbps. 
 I have multiple XGS's on HPE Aruba CX6x switches without problems, So you may want to check the switch.

For years there is a rare issue with auto negotation, which simply does not work in some setups. To bypass this, you have to set it manually on both ends. 
 If you are not doing this, and you run into such a limitation, it will automatically use the slower speed.
