The two built-in Ethernet 10/100 interfaces are Fast Ethernet 0/0 and Fast Ethernet 0/1.
The logical slot number for all 2-port T1/E1-RAN interfaces in the built-in 2-port T1/E1-RAN slot
is always 0. (The W0, W1, and W2 slot designations are for physical slot identification only.)
Interfaces in the 2-port T1/E1-RANs are numbered from right to left, starting with logical 0/0 for
each interface type, regardless of the physical slot in which the 2-port T1/E1-RANs are installed.
For example, if you have a 2-port T1/E1-RAN in two of the 2-port T1/E1-RAN slots (physical W0
and W1), then the logical 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 2-port T1/E1-RAN in physical slot W1 (leaving slot W0 empty), the logical
interfaces in slot W1 are Serial 0/0 and Serial 0/1. If you later add a 2-port T1/E1-RAN to slot W0,
the interface numbering shifts. The configuration that you created for logical interfaces Serial 0/0
and Serial 0/1 will now be applied to the 2-port T1/E1-RAN in physical slot W0, and you will need
to create a new configuration for the logical 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 logical slot number for all network module interfaces is always 1, and the interfaces are always
numbered from right to left, starting with 1/0.
