Identifying the Sensing Interfaces
Chapter 3
The quad-port 1000BASE-SX fiber configurable bypass configuration uses LC-type
(Local Connector) optical transceivers.
You can use this configuration to passively monitor up to four separate network
segments. You also can use paired interfaces in inline or inline with bypass mode,
which allows you to deploy the managed device as an intrusion prevention
system on up to two separate networks.
TIP!
For best performance, use the interface sets consecutively. If you skip
interfaces, you may experience degraded performance.
If you want to take advantage of a device’s automatic bypass capability, you must
connect the two interfaces on the left or the two interfaces on the right to a
network segment. This allows traffic to flow even if the device fails or loses
power. You must also use the web interface to configure a pair of interfaces as an
inline set and enable bypass mode on the inline set.
Dual-Port 10GBASE (MMSR or SMLR) Fiber Configurable Bypass NetMod
The dual-port 10GBASE fiber configurable bypass configuration uses LC-type
(Local Connector) optical transceivers. Note that these can be either MMSR or
SMLR interfaces.
You can use this configuration to passively monitor up to two separate network
segments. You also can use paired interfaces in inline or inline with bypass mode,
which allows you to deploy the managed device as an intrusion prevention
system on a single network.
TIP!
For best performance, use the interface sets consecutively. If you skip
interfaces, you may experience degraded performance.
