Erich,

Cisco routers are known for changing the interfacenumbers when rebooting
after a change in the configuration. 
You can circumvent this by using '--ifref=name' or '--ifref=descr' in
the configmaker command. 

HTH,

Jan.

Hi,

We are doing nice graphs of all the ports on a Cisco 3661 Router
(Modules: 1 x Dual Ch E1 1 x 16 port Switchmodule) but every so often -
(router rebooted last Saturday) the data for each client moves up (or
down one slot)???

How can one stop this?

Regards - Erich

Extra Info:

controller E1 1/0
 channel-group 1 timeslots 1-8
 channel-group 21 timeslots 21-24
                                  Now I add 25 and all my nice graphs
move up one!  channel-group 26 timeslots 26  channel-group 27 timeslots
27  channel-group 28 timeslots 28  channel-group 29 timeslots 29
channel-group 30 timeslots 30  description ChE1 71-09837-00 ! controller
E1 1/1  channel-group 1 timeslots 1-8  channel-group 21 timeslots 21-24
channel-group 26 timeslots 26  channel-group 27 timeslots 27
channel-group 28 timeslots 28  channel-group 29 timeslots 29
channel-group 30 timeslots 30  description ChE1 71-03036-00 !

Tried to edit the mrtg log files but that also caused havoc!
