•
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.
