Hi there,
I've a strange problem that I hope someone can help me with. I had configured a trunk port between Cisco 3560 and Ericsson switch on the
3650 the port is configured as
switchport trunk encapsulation dot1q
switchport mode trunk
same on the Ericsson side, everything was working great for a year until couple of days ago it all stopped working.
I rebooted both switches but it didn't work either.
when I switched the port on both sides to access port it started working again.
I don't have any problem with setting the port as access, but I can't understand the reason behind it.
does anyone have a clue.
thanks
