Note
Throughout this section, we refer to a WAVE appliance configured for inline
interception mode as a
WAVE inline appliance
.
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.
InlineGroup interfaces are numbered using the format slot/group. The slot number
is the slot in which the adapter is inserted. 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 watchdog
timer (WDT) controller that allows you to 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, the traffic is bridged
between the LAN and WAN ports of each group. Mechanical bypass mode
prevents the WAVE appliance from becoming a single point of failure and allows
traffic to continue to flow between the router and the client while it passes through
an unresponsive WAVE appliance without being processed.
For more information about configuring the inline network adapter, see the
Cisco
Wide Area Application Services Configuration Guide.
