Functional Overview
This section provides a functional overview of the Cisco 7206. It describes the numbering and
addressing scheme of the port adapters for the router, the environmental monitoring and reporting
functions, and online insertion and removal (OIR). These descriptions will help you become familiar
with the capabilities of the Cisco 7206 router.

Port Adapter Slot and Logical Interface Numbering

In the Cisco 7206, the port adapter slot number is the chassis slot in which a port adapter or service
adapter is installed, whereas the logical interface number is the physical location of the interface port on
a port adapter (service adapters do not have interface ports). Port adapter slots are numbered from 1
through 6; port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if
present. (Refer to
interfaces depends on the type of port adapter.

Server documentation listed in the Preface,
The Media Access Control (MAC) or hardware address is a standardized data link layer address that is
required for certain network interface types. These addresses are not used by other devices in the
network; they are specific and unique to each port. The Cisco 7206 uses a specific method to assign and
control the MAC addresses of its port adapters. For a description of the MAC address, refer to the
