Scenario 3—Multiple SA7100/SA7120s,
Cascaded
This scenario shows how to cascade SA7100/SA7120s for additional
performance and availability. The same procedures apply that were
performed in Scenario 3. In addition, the complete configuration of
the first SA7100/SA7120 is exported to the second SA7100/SA7120
in line.
Initial
Configuration • Two or more SA7100/SA7120s must be physically installed on
the same network. To cascade multiple SA7100/SA7120s,
connect from the server port of the first SA7100/SA7120 to the
network port of the next SA7100/SA7120 in line, and then again
connect from the server port to the network port of the next
SA7100/SA7120 in line, or to the server. (See Chapter 2 for more
information.)
• On the first SA7100/SA7120, the set spill enable command is
used to enable spilling so that the next SA7100/SA7120 in line
can handle the overflow. Spill is then enabled for each
subsequent SA7100/SA7120, except the last one. Do not
configure the last SA7100/SA7120 to spill to the server.
• The first SA7100/SA7120 should be fully configured; any
necessary keys, certificates or maps must exist. The complete
configuration is exported from the first, then imported to the next
SA7100/SA7120 in line. This procedure is repeated for any
additional SA7100/SA7120s in line.
