Redundant Pairs
You can purchase two ARX
®
6000 switches and configure them as a
redundant pair. If the primary switch fails, all services “fail over” to the
secondary switch. This is a highly-available configuration.
The redundant switches are interconnected through one or more of their
Gigabit Ethernet ports. You use the CLI to configure the ports for
redundant-link traffic (as opposed to client/server traffic).
See the ARX® CLI Network-Management Guide
and ARX® CLI Reference
for information about configuring redundant switches.
If you are installing the second switch in a redundant pair, there are
differences in the initial-boot procedure. The differences are outlined later in
Chapter 7,
Connecting the Switch to the Network.
Resilient Overlay Network (RON)
You can connect multiple ARX
®
es together in a Resilient Overlay Network
(RON). A RON is composed of a series of IP tunnels between the switches.
You can use the CLI to configure a RON tunnel, as described in the CLI
manuals.
See the ARX® CLI Network-Management Guide
and ARX® CLI Reference
for information about configuring RON tunnels.

a.The SCM always uses slot 1.
b.Service modules may use any of slots 2–6. For in-chassis high availability,
redundant modules are installed in adjacent slots, for example, ASMs in slots 3 and
4, and NSMs in slots 5 and 6.
