Configuring the Cisco IDS Router / Switch Modules for Cisco 6500 Switch / 7200 Router

IDSM-2

The IDSM-2 Module is a Cisco IDS blade for the Cisco 6500 switch.
Once you install the module into the switch the module uses following logical ports :

Port 1	Used for TCP Resets (In Promiscuous Mode)
Port 2	Command and Control
Port 7	Sensing Port
Port 8	Sensing Port

Below details the steps required for configuring your switch / module for an inline setup. This includes obtaining the module number for the cisco ids running the setup wizard and then assigning the required ports for on the switch for ids sensing within an inline configuration. The clear trunk commands are required as by default the switch assigns the ports as trunk ports to every vlan.

How to configure a Cisco Layer 3 switch-InterVLAN Routing

Cisco Catalysts switches equipped with the Enhanced Multilayer Image (EMI) can work as Layer 3 devices with full routing capabilities. Example switch models that support layer 3 routing are the 3550, 3750, 3560 etc.

On a Layer3-capable switch, the port interfaces work as Layer 2 access ports by default, but you can also configure them as “Routed Ports” which act as normal router interfaces. That is, you can assign an IP address directly on the routed port. Moreover, you can configure also a Switch Vlan Interface (SVI) with the “interface vlan” command which acts as a virtual layer 3 interface on the Layer3 switch.

On this post I will describe a scenario with a Layer3 switch acting as “Inter Vlan Routing” device together with two Layer2 switches acting as closet access switches.
