Clavister E80 unable to set static speed on interface

Post by johnhenriksson » 29 Sep 2020, 11:10

Hi! I'm trying to set static speed of the G1 interface on an E80. I'm able to specify the setting of 1000M on the interface page but the status is still 100M, even after reboot. Do I need to adjust any other settings to make it apply? I'm running cOS 13.00.06.06-35348

Hello.

I believe this is a negotiation between the Firewall and the equipment the Firewall is connected to. So if you set 1000 MBit on the Firewall and the other side wants to use 100 Mbit, we will lower the speed to match it.

It is also a bit dependent on the driver as some drivers/chipsets may react differently but i believe in general this is the most common behavior, especially since the following change (from Wikipedia):
The debatable portions of the autonegotiation specifications were eliminated by the 1998 release of 802.3. This was later followed by the release of the Gigabit Ethernet standard IEEE 802.3ab in 1999.
https://en.wikipedia.org/wiki/Autonegotiation

So i would start by checking the interface settings on the equipment the Firewall is connected to on this interface.

Best regards
