Chapter 1 Cisco 7200 VXR Product Overview
Functional Overview
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 1-31) and slot 1 through slot 6 in the Cisco 7206VXR (see
Figure 1-32). Port adapter slot 0 is always reserved for the Fast Ethernet port on the I/O controller—if
present.
