OL-12851-01
Fast Ethernet HWICs Port Numbering
Port numbers identify the interfaces on the modules and interface cards installed in the router. Modules
and interface cards are identified by three digits: slot number/subslot number/port number.
For example, HWIC port 0 in HWIC subslot 1 of router slot 0 is represented as:
interface FastEthernet 0/1/0
Fast Ethernet HWICs LEDs
The Fast Ethernet HWICs use three LEDs per port to indicate full- or half-duplex operation, collisions,
speed, transmit/receive activity, and link status.
Figure 113
and
Figure 114
show the HWIC-1FE and
HWIC-2FE faceplates, and
Table 33
describes the functions of the LEDs.
