when trying to configure a 2811 with 3 ethernet modules, the dynamic configuration tool shows the following error:
1. Incorrect quantity of etherswitch modules (i.e. HWIC-ESW, NM-ESW) selected. Currently there are  ESW modules selected for [CISCO2811]. Please select between 0 and 2.
is there a restriction for the HW configuration on a 2811? can you please provide link to documentation?
