Positioning 7110/7115 between ITM
Device and Server
If security considerations require limited network access to clear text,
the 7110/7115 should be placed between the ITM device and the
server.
NOTE: The
configuration in Figure
1-4 precludes layer 7
load balancing because
secure traffic through the
ITM device is encrypted.

Scalability and Cascading
The 7110/7115’s capabilities are scalable by chaining, or
“cascading,” multiple 7110/7115s together. In such configurations,
each unit’s server side connector is wired to the network side
connector of the next 7110/7115 in line. The last 7110/7115 in line is
connected to the server, switch, or ITM device.
Spilling and Throttling
When the 7110/7115’s “spill” option is enabled, if a given 7110/7115
cannot process a request within a specified interval, the request is
passed on, still encrypted, to the next 7110/7115 in line. The last
