Chapter 4 WAVE Inline Network Adapter
Inline Network Adapter Description
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.
