When the Bypass Switch is in Bypass Enabled
mode, all in-line traffic continues to flow on the
network link without being directed through the
Juniper IDP appliance
Because in-line traffic is no longer
flowing through the IDP, the appliance
may be removed and replaced without
downtime.
When there is no power to
the Bypass switch, it enters
Bypass Enabled mode.
