4-8
z
The interfaces are represented by
interface-type X/Y
, where
interface-type
can be serial,
asynchronous, or Ethernet, and so on;
X
specifies the slot number;
Y
specifies the interface
number.
z
Different interfaces on an interface module share the same slot number X.
z
For every interface, Y starts from 0 and Y indicates the interface sequence on the interface module,
from left to right.
If you install an SIC-1FEA and an SIC-4FSW respectively in SLOT1 and SLOT2 on the AR MSR 20-20,
the Ethernet interfaces are numbered as follows:
z
Fixed Ethernet interfaces are Ethernet 0/0 and Ethernet 0/1;
z
The Ethernet interface on the SIC-1FE is Ethernet 1/0;
z
The Ethernet interfaces on the SIC-4FSW module are Ethernet 2/0, Ethernet 2/1, Ethernet 2/2 and
Ethernet 2/3.
