Numbering interfaces
Before installing a HIM/MIM, you must install a FIP. A FIP20 supports both HIMs and MIMs, while a
FIP-10 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-10 is installed in slot 1 and a MIM-2GBE module is installed on the FIP-10.
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
