Re: Auto Negotiation Advertise doubt

For SFP/SFP+ cages, highest rate supported by the module will be chosen. Setting speed to 1Gbps and disabling auto-negotiation is needed when you use SFP modules in SFP+ cages, or if you use SFP+ modules in SFP cages. That being said there are modules that support auto-negotiation, such as S-Rj01 an...

What did you mean by "when 2 ports of the same device are connected (MikroTik and Huawei) through the MikroTik passive cable, the ports are rising." ?

Re: CRS326-24S+2Q+RM Question

CRS326-24S+2Q+RM is meant to be used primarily as a switch. You can use 1000Base-T transceivers, we have our own as well - S-Rj01 and S+Rj10. And you can also use SFP modules in SFP+ cages, you will just have to disable auto-negotiation on the port and set the speed manually to 1Gbps.

Re: Please help!!!!

If it's hEX POE, then first solution is not applicable as it doesn't have serial port.
Now you could do as cdiedrich said, and make a script that would log you in and disable Netwatch. Or you can try adding host with that IP. If neither of these is an option, then you have to reset the device.

If the device has serial port, connect via that and after boot up paste this command in "/tool netwatch set [f] disabled=yes".

Re: rb750gr3 Gigabit auto negotiation [SOLVED]

You should use "/interface ethernet monitor", as that is where actual link rate is displayed. Export is not correct tool for checking rate, as it is dynamic value and can change in case of auto-negotiation, or it can be non-existent if link is not up. Since by default auto-negotiation is enabled and...

What tdw wrote is correct. "speed=" is only taken in account when you disable auto-negotiation. If you have auto-negotiation enabled, then "advertise=" values are used instead.

CCR1016-12S-1S+ has "sfpplus1" cage, not "sfp-sfpplus1", so it can only work with "SFP+" modules, and not "SFP" modules, that might be related to your problem.

You need to adjust both L2MTU and MTU values for interface, and if interface is part of a bridge, check MTU values for the bridge and other bridge ports as well.
