For example, if you have a VWIC in two of the VWIC slots (W0 and W1), then the interfaces are:
Serial 0/0 and Serial 0/1 in physical slot W0
–
Serial 0/2 and Serial 0/3 in physical slot W1
–
However, if you install a VWIC in physical slot W1 (leaving slot W0 empty), the interfaces in slot
W1 are Serial 0/0 and Serial 0/1. If you then add a VWIC to slot W0, the interface numbering will
shift. The configuration that you created for interfaces Serial 0/0 and Serial 0/1 will now be applied
to the VWIC in slot W0 and you will need to create a new configuration for the interfaces that you
previously configured on W1 (which will now be Serial 0/2 and Serial 0/3).
The slot number of WIC/VWIC interfaces installed in slot 1 using a WAN network module is always
1 and the interfaces are always numbered from the right to left.
The slot number for all network module interfaces is always 1 and the interfaces are always
numbered from right to left starting with 1/0.
