Online Insertion and Removal
If the MAC addresses were stored on each shared port adapter, online insertion and removal would not function
because you could never replace one shared port adapter with an identical one; the MAC addresses would
always be different. Also, each time a shared port adapter was replaced, other devices on the network would
have to update their data structures with the new address. If the other devices did not update quickly enough,
the same MAC address could appear in more than one device at the same time.
Storing the MAC addresses for every slot in one central location means the addresses stay with the memory
Note
device on which they are stored.
Online Insertion and Removal
In the modular chassis configurations, most Cisco ASR 1000 Series Router field-replaceable units (FRUs)
support online insertion and removal (OIR). However, the removal of critical non-redundant FRUs will result
in service interruption.
As you disengage the shared port adapter from the router, online insertion and removal (OIR)
Note
administratively shuts down all active interfaces in the shared port adapter.
Online insertion and removal (OIR) feature allows you to install and replace shared port adapters while the
router is operating; you do not need to notify the software or shut down the system power, although you should
not run traffic through the shared port adapter you are removing while it is being removed. Online insertion
and removal is a method that is seamless to end users on the network, maintains all routing information, and
preserves sessions.
All SPA OIR events are independent of one another. An OIR event of a single SPA does not affect the other
SPAs in that ASR1000-SIP10 or any other system function.
The following items describe the OIR differences between the Cisco ASR 1002 Router, the Cisco ASR 1002-F
Router, and the Cisco ASR 1002-X Router:
• The Cisco ASR 1002 Router supports the integrated Cisco ASR1000-RP1, which is a combined route
• The Cisco ASR 1002-F Router supports an integrated route processor Cisco ASR1002-RP1 and an
• The Cisco ASR 1002-X Router supports an integrated route processor (Cisco ASR1002-RP2) and an
The following is a functional description of OIR for background information only; for specific procedures
for installing and replacing a shared port adapter in Cisco ASR 1000 Series Routers, refer to the online
configuration note for each shared port adapter.
