Chassis Slot and Logical Interface Numbering

In the Cisco 7200 VXR routers, the port-adapter-slot-number is the chassis slot
in which a port adapter is installed, whereas the logical-interface-number is the
physical location of the interface port on a port adapter.
Port adapter slots in the Cisco 7200 VXR routers are numbered from left to
right— slot 1 through slot 4 in the Cisco 7204VXR (see Figure 1-26) and slot 1
through slot 6 in the Cisco 7206VXR (see Figure 1-27). Port adapter slot 0 is
always reserved for the Fast Ethernet port on the I/O controller—if present.
