I think I deleted my message befor I posted it, so here it goes again
(maybe)

I have a 2900xl with (2) vlans one for cable and the other
for dial-up modem/router. What I want to know is there anyway to
switch config files by way of a batch file. What I'd like to be able
to do is if the cable goes out have the 2900 get a second config file
loaded. This config would switch all the ports that are set for cable
vlan to the vlan for the dial-up modem/router. I'd ping my cable isp
or google to see if the cable was ok, if it timed out run a batch file
(of some sort) that would load the second config file. That would
switch all the ports that are on the cable vlan to the vlan for the
dial-up modem/router vlan. Can this be done?
Many Thanks..
