Figure 1.6 Sample Network
The sample network has redundant ARX devices connected at each of the
distribution switches. Physically, this is a one-armed connection;
conceptually, the ARX has clients in front and file servers in back.
The network file servers are the storage behind the (front-end) services of
the ARX. The servers can be heterogeneous: NAS devices and file servers
need only support CIFS or NFS.
Table 1.2 lists the ports required by the ARX to communicate with its
authentication services, back-end storage, and front-end client services. If
you plan to operate in a secure environment, these ports must be opened on
fire walls in order for the ARX to function properly.
All client/server data is on the inband network. The inband network enables
clients and servers to talk to the ARX. The higher layer protocols use the
inband network. If traps and email home are configured, they also use the
inband network.
The out-of-band network is used to connect to the CLI or the GUI for
purposes of querying or configuring the ARX.
There is a third network (heartbeat) between the two ARX devices in a
high-availability configuration that is used to pass redundancy information
between the switches.
