#sh run int fa 0/1:
Unknown cisco device, perhaps, ME series switch (3400 or so..):
#sh run int Fa0/1interface FastEthernet0/1 description TEST port-type eni switchport access vlan 5 l2protocol-tunnel cdp l2protocol-tunnel stp l2protocol-tunnel vtp
When both ports are hardcoded to speed 100/duplex full - then they do not come up.
When they are set to auto (as shown in config) - they come up with 100/half-dup at both ends.
What could be the problem? Perhaps physical layer (bad line)? Or what?
Thanks in advance.
Have you tried a cross-over cable between the 2 switches?
100/half is the default setting for switchports which fail the auto-negotiation exchange, that indicates one side if failing to negotiate. What happens when you set the 2960 to auto, and the ME for 100/full?
Thanks to all.
There was a switch-in-the-middle.At least it was set to 100/full. So ports on end points were set.
It works now as it should.
