Route Switch Processor (RSP16) Installation and Configuration Guide
OL-4661-03
  Configuring High System Availability
You can also use HSA for advanced implementations. For example, you can configure the RSP16 cards
with the following:
Similar software versions, but different configuration files
Different software images and different configuration files
Widely varied configuration files (for example, various features or interfaces can be turned off or on
per card)
Note
Other, more complex uses of HSA are also possible, but are not addressed in this document. For more
information, contact your Cisco service representative.
HSA System Requirements
To configure HSA operation with the RSP16, you must have:
A Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX containing one RSP active
processor card, one RSP standby processor card, and the proper Cisco IOS release (refer to the
Software Advisor at
http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl
for additional
information).
A standby RSP with the same (or higher) DRAM and Flash memory capacity as the active RSP. See
the
A standby RSP with the same boot image, the same ROM monitor, and the same DRAM
configuration as the active RSP. (See the
Caution
The HSA feature works with two RSP16 cards, or with one RSP16 and one RSP8. The RSP16 cannot be
used in combination with any other RSP cards when utilizing the HSA feature.
HSA Configuration Task List
Before you configure HSA, decide how you intend to use HSA. Do you want it for simple hardware
backup or for software error protection? If you are using new or experimental Cisco IOS software,
consider using the software error protection method; otherwise, use the simple hardware backup method.
After determining how you intend to use HSA, complete the tasks in the following sections. The first
two and last two tasks are required for both implementations. The third and fourth tasks relate to simple
hardware backup. The fifth task relates to software error protection only.
