Figure 1-15 Inline Network Adapter
The Cisco WAE inline network adapter provides inline traffic interception
capability for your appliance. When your appliance is configured for inline
interception mode, you can set attributes to control which interfaces are to be used
over which VLANs. By default, the adapter operates on all inline-capable
interfaces and VLANs. You can configure the inline redirection feature using the
WAAS 4.0.7 CLI or the WAAS 4.0.7 Central Manager GUI.
The WAAS software defines two new interface types: A group interface that
represents an inline pair grouping and a port interface that represents the
individual port. These interfaces are referred to as inlineGroup and inlinePort,
respectively.
InlineGroup interfaces are numbered using the format slot/group. The slot number
is the slot in which the adapter is inserted. (In the WAE 500 series and 600 series
appliances, the adapter must be installed in slot 1 only.) The group number is
either 0 or 1 (each adapter has 2 group pairs). The group number is displayed on
the adapter label.
InlinePort interfaces are numbered slot/group/lan or slot/group/wan. The last
attribute is the LAN or WAN designator.
The inline network adapter also includes an onboard programmable Watch Dog
Timer (WDT) controller. You can set the time to wait after a failure event, such as
a power outage or a kernel crash, before the unit begins to operate in mechanical
bypass mode. In mechanical bypass mode, traffic is bridged between the LAN and
WAN ports of each group. Mechanical bypass mode prevents the WAE from
