Booting the Switch
ARX-500 Hardware Installation Guide
3 - 7
Every ARX keeps its local network parameters in its running-config, and
every redundant pair of ARX devices share a single global-config with all
namespace and service parameters. An ARX startup-config contains both its
running-config and global-config in a single file. Therefore, a redundant pair
requires two or more saved configuration files:
• Two startup-configs (one per ARX), or
• Two running-configs (one per ARX) and a single global-config
To replace a single switch, you also need:
• Master key (extracted and wrapped)
• Master key wrapping key password
Choosing Switch Replacement
When the initial-boot script asks if this is a switch replacement, answer
yes
to invoke the questions required to replace the failed switch as in the
following example.

Matching the Private Subnet
The next set of questions ask for the switch’s
private subnet
, the
private
VLAN
for that subnet, and the VLAN for a
private
metalog subnet
. If the
failed switch was in a redundant pair and/or Resilient-Overlay Network
(RON), the private subnets of the replacement switch should match those of
the switch that failed. Each ARX uses its private subnet for communication
with other ARXes in the same RON and/or the switch’s redundant peer. All
private subnets in the RON and/or pair are carried by the same VLAN. This
private VLAN, and the separate metalog VLAN, must be reserved for ARX
traffic only.
The private subnet and VLAN information appear at the top of the output of
the
show running-config
command for a failed switch as shown in the
following example. The private subnet information is highlighted in bold.
