System Role
The choice of System Role (or simply "role") depends in part on your
network’s topology and on the number of SA8250s installed. A single
SA8250’s role must be "Standalone." If two SA8250s are employed,
and you intend to use serial cable failover you must designate both
SA8250s as "standalone." If two SA8250s are employed, and you
intend to use Router Failover, one must be designated as the
"Primary" and the other as the "Backup." In such cases, the primary
SA8250 accepts all client requests and routes them according to its
configuration while the backup SA8250 monitors the primary and
comes online if the primary fails.
The system roles are defined in this table.
To select the SA8250’s System Role:
1. In the System Role box, click the appropriate button.
Active Routing Protocol
The SA8250 needs to know what your network’s active routing
protocol is (either OSPF or RIP).
1. In the Active Routing Protocol box, click the appropriate radio
button.
RIP Protocol
If your network’s active routing protocol is RIP, click the appropriate
button in the RIP Protocol box to specify the applicable RIP version.
