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
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
