■
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.
■
Different interfaces on an interface module share the same slot number X.
■
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:
■
Fixed Ethernet interfaces are Ethernet 0/0 and Ethernet 0/1;
■
The Ethernet interface on the SIC-1FE is Ethernet 1/0;
■
The Ethernet interfaces on the SIC-4FSW module are Ethernet 2/0, Ethernet
2/1, Ethernet 2/2 and Ethernet 2/3.
