6-Port 1-Gb SX/10-Gb SR/10-Gb LR/25-Gb SR/25-Gb LR Network Module with Hardware Bypass

hardware bypass network modules have a switch that is capable of connecting the two ports when needed.

This hardware bypass network module has built-in SFPs.

Note

Hardware bypass is only supported with threat defense, although you can use these modules in nonbypass

mode in threat defense or ASA.

Hardware bypass is supported only on a fixed set of ports. You can pair Port 1 with Port 2, Port 3 with Port

4, but you cannot pair Port 1 with Port 4 for example.

Note

When the appliance switches from normal operation to hardware bypass or from hardware bypass back to

normal operation, traffic may be interrupted for several seconds. A number of factors can affect the length of

the interruption; for example, behavior of the link partner such as how it handles link faults and debounce

timing; spanning tree protocol convergence; dynamic routing protocol convergence; and so on. During this

time, you may experience dropped connections.

Note

If you have an inline interface set with a mix of hardware bypass and nonhardware bypass interfaces, you

cannot enable hardware bypass on this inline interface set. You can only enable hardware bypass on an inline

interface set if all the pairs in the inline set are valid hardware bypass pairs.

Note

The 6-port 1-Gb SX/10-Gb SR/10-Gb LR/25-Gb SR/25-Gb LR network module is supported beginning with

FTD 7.2.3 and ASA 9.18.2.

Note

The hardware and the system support hot swapping if you are replacing a network module with the same type

of network module. If you replace the 6-port 1/10/25-Gb network module with another supported network

module, you must reboot the chassis so that the new network module is recognized. See the configuration

guide for your operating system for the detailed procedures for managing network modules.

Note

Make sure you have the correct firmware package and software version installed to support this network

module. See the configuration guide for your software for the procedure to verify your firmware package and

software version. See the

operating system and hosting environment requirements, for each supported version
