IM-IPS Card Configuration

NOTE:

The IM-IPS card is only for the SR8800 routers.

Configuration Overview

The router and the SecBlade IPS card are connected through internal 10GE interfaces. With OAA

configured, the router automatically redirects traffic to the SecBlade IPS card through its 10GE interface.
After processing the traffic, the SecBlade IPS card sends the traffic back to the router through its internal

10GE interface, and the router forwards the traffic. The detailed data forwarding process is as follows.

From internal network to external network

1.

Packets from the internal network enter the router.

2.

The router redirects the packets to the SecBlade IPS card.

3.

The SecBlade IPS card processes the packets, and then forwards them back to the router.

4.

The router forwards the packets out its external network interface.
