Comtech EF Data / Stampede
Generate HTML error pages:
This controls whether the FX Series ADC should generate an HTML page describing the problem and
identifying the FX Series ADC when it encounters a problem connecting and/or receiving content from a
back-end server. The default value is "Enabled".
Preserve Client IP Addresses:
If enabled, then the FX Series ADC will send the requests to the back-end servers with a source IP address
that is the same as the client that the request is on behalf of. Enabling this setting may require a
Transparent Bridging configuration. This setting only applies to single-sided optimization. IP source
preservation with FX Remotes is specified in the L5 application policies. The default value is "Enabled".
4.1.2 Object Retrieval Logging
Log HTTP Requests:
Enables logging of URLs for all HTTP web object retrievals in "common log format". The default setting is
"On".
Maximum Size in KB
This sets the maximum size of the object retrieval log file in kilobytes. When this size is reached
a backup is made and the file is reset. The default setting is 1000000 (1 GB).
4.1.3 Traffic Interception
Traffic interception mode:
This is the means by which the FX-ADC will transparently intercept packets. Choose
either "In-Line", "Routed", WCCP" or "Disabled". The default is "In-Line".
In-Line mode, the LAN port is eth2 and the WAN port is eth3. Traffic is
intercepted as a transparent bridge. If there is a service disruption then the
units will "fail-to-wire". In bridged mode, you must assign an IP address to the
in-path interface which bridges the LAN and WAN interfaces. In FX nomenclature, the "WAN"
interface is considered to be the interface which is connected to the satellite modems and the
LAN interface is connected to the internet or to enterprise servers.
In routed mode, traffic must be directed to these interfaces by a router. You must assign an IP
address to the in-path interface which will receive traffic from the router. There is no "fail-to-
wire" capability if there is a service disruption.
In WCCP mode, traffic is redirected to the FX by a Cisco router via WCCP.
If "Disabled" then traffic redirection is effectively shut off.
VLAN mode:
This controls how the FX will process VLAN tags. In 'Trunk' mode, the VLAN tags are already embedded in
the packets when they are intercepted by the FX. In 'Access' mode, the FX will add tags to untagged
traffic. The default setting is 'Trunk'.
Note: Changing either the 'Traffic interception mode' or 'VLAN mode' settings will automatically
trigger a restart of the acceleration service.
Fail-to-wire mode:
If enabled, the FX will go into bypass mode it is not accelerating traffic or if it is powered off. If disabled, it
will not go into bypass mode which will prevent packets from being forwarded through the FX. If the FX is
adding the VLAN tags to the traffic, it may be desirable to disable 'Fail-to-wire' mode to prevent untagged
traffic from entering a network.
The default setting is "Enabled".
Note: The FX-1010 does not support fail-to-wire mode
