Configuring Management IP Addresses
You can configure in-band management interfaces, one per configured
VLAN. At least one such interface is required for many installations – and
adding at least one in-band management interface is strongly recommended
in any case.
◆
A switch in a Resilient Overlay Network (RON) of switches requires at
least one in-band management address. A RON is a network of IP
tunnels that connects multiple ARXes together. Each tunnel requires an
in-band IP address as an endpoint. You can re-use the same in-band
management IP for multiple RON tunnels, but at least one is required.
◆
Redundant switches also require at least one in-band management
interface to communicate with shared, external resources (the quorum
disk).
The ARX also has an interface for out-of-band management (typically
labeled
MGMT ) on its front panel. This interface is designed for installations
with discrete management networks. It must have an IP address outside of
the server subnet or any of the client subnets.
Note
ARX-VE does not offer out-of-band management.
Ports Required by the ARX
The ARX is assumed to operate in a three-tiered network in a large data
center. The first tier is core routers that provide connectivity to a campus or
WAN. The second tier has redundant distribution switches that distribute all
data center traffic between the access switches; the access switches
constitute the third tier of the network. All LAN clients and back-end file
servers connect to the access switches. Through the access switches and
distribution switches, LAN clients connect to all back-end servers/storage,
to one another, and to the WAN.
Figure 1.6 shows a sample network.
