Hello all
I do not have much experience working with juniper and I'm having issues with one ex 4300, it is suposse that ex4300 will replace a cisco switch that is on production now, but when I tried to do the change there are several interfaces that don't not come up. I think it is a mismatch issue between the configurations. As troubleshoot I ereased the speed and full duplex and I set the interfeces with negotiation-auto but did not work, also I erased the port security but not success. Any idea of what is the cause of this negotiation failed or incomplete.
Also I was looking for a command to monitor or debug the messages of the interfaces without lucky so I will realy appreciate if you can share how can I monitor the interface
Best regards
