Understanding Online Insertion and Removal
The online insertion and removal (OIR) feature supported on the Catalyst 6500 series switches allows 
you to remove and replace modules while the system is online. You can shut down the modules before 
removal and restart it after insertion without causing other software or interfaces to shut down. 
Note
Do not remove or install more than one module at a time. After you remove or install a module, check 
the LEDs before continuing. For module LED descriptions, refer to the Catalyst 6500 Series Switch 
Installation Guide
When a module has been removed or installed, the Catalyst 6500 series switch stops processing traffic 
for the module and scans the system for a configuration change. Each interface type is verified against 
the system configuration, and then the system runs diagnostics on the new module. There is no disruption 
to normal operation during module insertion or removal.
The switch can bring only an identical replacement module online. If the replacement module is different 
from the removed module, you must configure it before the switch can bring it online. 
Layer 2 MAC addresses are stored in an EEPROM, which allows modules to be replaced online without 
requiring the system to update switching tables and data structures. Regardless of the types of modules 
installed, the Layer 2 MAC addresses do not change unless you replace the supervisor engine. If you do 
replace the supervisor engine, the Layer 2 MAC addresses of all ports change to those specified in the 
address allocator on the new supervisor engine.
Monitoring and Maintaining Interfaces
You can perform the tasks in the following sections to monitor and maintain interfaces:

Monitoring Interface Status
The software contains commands that you can enter at the EXEC prompt to display information about 
the interface including the version of the software and the hardware and statistics about interfaces. The 
following table lists some of the interface monitoring commands. (You can display the complete list of 
show commands by using the show ? command at the EXEC prompt.) These commands are described 
in the Cisco IOS Interface Command Reference publication.
