Thanks Peter,
The problem is that this router is a 700 series - you know, the one without
the IOS.
Anyway(s), I went to the office and accessed the router via the local hub,
and fixed the problem.
Changing from 5ESS to NI-1 broke my connection with the network, and I
couldn't ping my servers. I therefore changed it back to 5ESS, and then it
worked again. The weird thing is, that doing that also fixed the problem, so
something (that I could not see anywhere in the configuration) got reset by
changing the switch type, and my network response time is now back to
normal.
I have now saved the configuration again, and here is how to do that btw:
upload tftp n.n.n.n router-x.txt
Should I ever need to restore the configuration, I can reset it and restore
it this way:
set default
swl tftp config n.n.n.n router-x.txt
I hate troubleshooting like that, because you cannot really put a finger on
what fixed the problem.
I can now sit down with one less problem and write mileage on my expence
report :-)
Have a great weekend,
Ole
