Interface numbering
The router's fixed Ethernet ports are numbered as follows:
•
The two fixed WAN ports are numbered Ethernet 0/0 and Ethernet 0/1.
•
The four fixed Ethernet LAN ports are numbered Ethernet 0/1, Ethernet 0/2, Ethernet 0/3, and
Ethernet 0/4.
This follows the router's numbering convention
interface-type
X/Y
, where:
•
interface-type
is the type of interface, such as serial, asynchronous, or Ethernet.
•
X
is the number of the slot where the interface module is installed. All ports on an interface module
have the same slot number.
•
Y
is the sequence number of an interface on an interface module. As you face the interface module,
the module's interfaces are numbered from left to right in ascending order, starting at 0.
Connecting the console cable and setting terminal parameters
Connecting the console cable
CAUTION:
When using a console cable to connect a PC to the router, first connect the DB-9 end of the console
cable to the PC serial port, and then connect the RJ-45 connector of the console cable to the router
console port.
To connect the console cable, as shown in
Figure 22
:
1.
Select a console terminal, which can be an ASCII terminal with an RS232 serial port or a PC. (A
PC is more commonly used.)
2.
Connect the DB-9 connector (female) of the console cable to the RS-232 serial port of the console
terminal and the RJ-45 connector to the console port of the router.
