Numbering interfaces
Before installing a HIM/MIM, you must install a FIP. A FIP20 supports both HIMs and MIMs, while a
FIP- 1 0 supports only MIMs.
The interfaces of the router are numbered in the form of interface-type X/Y/Z,
Where,
interface-type: Type of the interface such as GE port and serial port.
•
X: Number of the slot where the FIP resides.
•
•
Y: Sub-slot number—The number of the slot where the HIM/MIM resides on the FIP.
Z: Sequence number of the interface on the HIM/MIM.
•
NOTE:
Different interface modules on the same FIP have the same slot number X.
•
Different interfaces on the same HIM/MIM have the same sub-slot number Y.
•
•
For each type of interface, the sequence number Z starts from 0 on the interface module.
Examples
Example 1
A FIP- 1 0 is installed in slot 1 and a MIM-2GBE module is installed on the FIP- 1 0.
1.
If the MIM-2GBE is installed in slot 1 of the FIP-10, the GigabitEthernet interfaces are:
GigabitEthernet 1/1/0
•
GigabitEthernet 1/1/1
•
2.
If the MIM-2GBE is installed in slot 2 of the FIP-10/FIP-100/FIP-110, the GigabitEthernet interfaces
are:
•
GigabitEthernet 1/2/0
GigabitEthernet 1/2/1
•
Example 2
A FIP-20 is installed in slot 1 and a HIM-4GBE module is installed on the FIP20.
1.
If the HIM-4GBE is installed in slot 1 of the FIP20, the GigabitEthernet interfaces are:
GigabitEthernet 1/1/0
•
•
GigabitEthernet 1/1/1
GigabitEthernet 1/1/2
•
GigabitEthernet 1/1/3
•
2.
If the HIM-4GBE is installed in slot 2 of the FIP20, the GigabitEthernet interfaces are:
GigabitEthernet 1/2/0
•
•
GigabitEthernet 1/2/1
