This document provides background information and detailed procedures for cabling dual
Cassatt Active Response control nodes and network switches and for configuring those
network switches. These procedures are an example of one way you could cable the control
nodes and configure the switches. If your site setup differs, use this document as a guideline.
Prerequisites
This example assumes you have completed the following tasks:
You have obtained all the required hardware.
You have determined your network address strategy and allocated the required IP
addresses according to network requirements of
You have configured your gateway or gateways using the static IP addresses you allocated
from the Cassatt network.
See the
Info Central
Cassatt Active Response.
You must understand the switch and control node port numbering to cable the Cassatt Active
Response environment's hardware components together correctly. Figure 1 assumes use of a
Cisco switch and shows switch ports, the switch module ports, and the control node ports. As
an example, this document assumes four network switches intended for use with 24

  • Page 4 2. Follow the Cisco switch hardware installation instructions and use the StackWise cables to cable the four switches into two sets of switch stacks, as shown in Figure 2. Once the two 24-port switches have been stacked, they behave as a single logical 48-port switch.
  • Page 5 Connect port 1 on switch 2 to port 1 on switch 4. Connect port 2 on switch 1 to the edge router to make the first gateway connection. Connect port 2 on switch 3 to the edge router to make the second gateway connection.
  • Page 6: Connecting Switch To Terminal Server

    1. Connect the switch in a stack to a terminal server. It may be convenient to connect all switch consoles to the terminal server to avoid the need to move cables if a switch fails. Follow the switch connector and cable specifications in the Catalyst 3750 Switch Hardware Installation Guide to determine what type of cable is needed when connecting the switch for configuration.
  • Page 7: Restoring The Factory Default Settings

    Press RETURN to get started! Restoring the factory default settings To reset the switches in a switch stack to the factory defaults, you must delete the startup configuration and virtual local area network (VLAN) database files. Execute the following privileged command sequence to restore the Cisco Catalyst 3750 Series switch configuration to the original factory setting: 1.
  • Page 8 3. If the switch was used previously in a switch stack, and is now in a different switch stack, it may have a switch number other than 1 and 2. To determine if the switch number must be reset, display the switch configuration as follows: At this prompt...

  • Page 12 When possible, the two links of the port channel should be on different switches to provide reliability in case a complete switch goes down. In this reference configuration, stacked switches are used, so both ports are not on the same switch.

If the switches connect to a gateway device through another switch or a device that participates in spanning tree protocol, do not set that device. At this prompt...

  • Page 14 Ethernet interfaces, IGMP snooping, and multicast. By default, IGMP snooping is globally available on the switch. With IGMP snooping, multicast packets are forwarded only to the ports that have joined that multicast group. When IGMP snooping is disabled, multicast packets are forwarded to all ports on the switch.
