Cisco ASR 903 router Features

Supported RSP Features

The RSP provides the following features on the Cisco router:
•
•
•
•
•
•
•

RSP Redundancy

The Cisco ASR 903 router chassis includes two RSP slots to allow for redundant RSPs. When the router
uses redundant RSPs, one RSP operates in the active mode and the other operates in the hot standby
mode. Removal or failure of the active RSP results in an automatic switchover to the standby RSP.
If you are using redundant RSPs, both the RSPs must be of the same type because a mixed configuration
Note
of two different RSP types is not supported.

Network Timing Interfaces

The RSP supports the following network timing interfaces:
•
•
•
•
Network timing interfaces support redundancy in a redundant RSP configuration. Network timing
interfaces on a redundant RSP remain in operation while the RSP is in hot standby mode.
