It shouldn't happen , if you forgot the "add" command then yes it would make a difference. Have also seen if you use negotiated trunks "switchport mode dynamic desirable" that you should get both sides of the trunks done in a short period of time or the trunks will go down due to being mismatched . I usually just open up 2 windows in this case and add the commands quickly on each screen . I wonder if the trunk had all vlans allowed and when you put your command in it just put the one you added into the trunk ???
Yes I thought that but I added each vlan seperately and pressed the up arrow to add each vlan to make sure each one had taken. There were a few vlans set up to be accepted originally but as I say, adding those other caused it to spit its dummy out.
oh well, I wonder if it was just one of things.
typically it happened within a coupe of weeks of starting a new job
