Control Node and Network Switch Cabling
Example
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.
Cabling control node and switch hardware
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.

Port numbering
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

Racking and cabling guidelines
To cable your control nodes to the network switches according to Figure 1, follow these
steps. Remember that this sample configuration uses four network switches, so use these
instructions as a guideline for your own configuration.
1. Rack all switches and control node hardware according to the vendor’s documentation
and/or the site policy. For lack of any other policy, rack the heaviest of the following
pieces of equipment on the bottom:
• Cisco switches
• Power distribution units (PDUs)
• Control nodes
• Application nodes
see the
Info Central
site for detailed information on setting
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.
Figure 2 Stacked Switch Cabling
CASSATT ACTIVE RESPONSE CONTROL NODE AND NETWORK SWITCH CABLING EXAMPLE 19
3. Connect the control nodes to the shared storage hardware, as follows:
If... Then...
a SAN is used for shared storage • Insert a Host Bus Adapter (HBA) into each control
node.
• Connect one end of the fiber cable to the HBA and the
other end to your site's SAN.
a NAS and dual-ported disk is used
for shared storage
• Insert the connectivity card required for the dualported disk into each control node.
• Connect the other end of each card to the dual-ported
disk.
4. Using crossover cables, create an interswitch link (ISL) between the two Cisco 3750
switches. The recommended configuration uses two ISL connections between the Cisco
switches for increased bandwidth and redundancy. As suggested in Figure 1, create the
first half of the ISL between the stacked switches, as follows.
• Connect port 1 on switch 1 to port 1 on switch 3.
5. Then create the second half of the ISL between the stacked switches as follows:
• 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.
6. Using the Cisco switches and control node port information in Figure 1, connect the
control nodes to the switches using category 5 or 6 Ethernet cables. The recommended
configuration uses dual Ethernet connections to each control node for redundancy. Do
this as follows:
• From control node 1's back panel:
- Connect Gb1 port 1, C1-1, into port 3 on switch 1
- Connect Gb2 port 2, C1-2, into port 3 on switch 3
- Connect the remote management controller port, C1-P, into port 24 on switch 4
• From control node 2's back panel:
- Connect Gb1 port 1, C2-1, into port 4 on switch 1
- Connect Gb2 port 2, C2-2, into port 4 on switch 3
- Connect the remote management controller port, C2-P, into port 24 on switch 2
If you are cabling application nodes, you can follow the diagram in Figure 1. For more
application-node specific cabling instructions, see the
CASSATT ACTIVE RESPONSE CONTROL NODE AND NETWORK SWITCH CABLING EXAMPLE 20
Info Central
site.
Configuring the switches
After you have racked and cabled the control nodes and switches, you need to configure both
Cisco switch stacks. If you are using another of the Cassatt recommended switches (see the
Info Central
as a guideline.
Do not configure network switches to enforce a maximum number of Ethernet addresses
learned on an interface. For example, on Cisco switches, do not use “switchport portsecurity.” Doing so may prevent
discovery process.
Connecting the switch to a terminal server
To configure the first Cisco Catalyst 3750 Series switch stack to a Lantronix terminal server,
do the following. If you are using another terminal server, use this Lantronix configuration as
a guideline.
1. Unplug the network switches.
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. The RJ-45-to-DB-9 adapter cable
that comes with the switch for this connection was not used for the reference
configuration testing.
site for recommended switch hardware), use this Cisco switch configuration

At this prompt... Enter... Notes
Switch(config)# interface range GigabitEthernet 1/0/1 – 24
Switch(config-ifrange)#
Switch(config-ifrange)#

exit
This step is done to prevent
network loops from forming
because the configuration is only
partially enabled at this time.
6. Turn off all the interfaces on the second switch, as follows:
At this prompt... Enter... Notes
Switch(config)# interface range GigabitEthernet 2/0/1 – 24
Switch(config-ifrange)#
Switch(config-ifrange)#

This is done for the same reason as
stated in the previous step.
7. Set the host name of the switch stack, as follows:
At this prompt... Enter... Notes
Switch(config)# hostname sw01
Use your site-specific name instead
of sw01 used as an example; each
switch should have a unique name.
8. Set the switch stack’s enable password, as follows:
At this prompt... Enter... Notes
sw01(config)# enable secret system
Use your site-specific password
instead of the system password used

11. Aggregate the two physical links between the two Cisco switches in the stack into a single
logical link, as follows:
At this prompt... Enter... Notes
sw01(config)# interface GigabitEthernet1/0/1
The single logical link provides
both reliability and higher capacity.
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. The manual
configuration of the port channel
is required when the interfaces are
on different switches.
sw01(config-if)# channel-group 1 mode on
Displays the following output:
Creating a port-channel interface Port-channel 1

13. Set the remaining interfaces, which are identical, as follows.
If the switches connect to a gateway device through another switch or a device that
participates in spanning tree protocol, do not set
spanning tree portfast
that device.
At this prompt... Enter... Notes
for the link to
sw01(config)# interface range GigabitEthernet 1/0/3 – 24
sw01(config-if-range)# spanning-tree portfast
%Warning: portfast should only be enabled on ports connected to
a single host. Connecting hubs, concentrators, switches,
bridges, etc... to this interface when portfast is enabled, can
cause temporary bridging loops.
Use with CAUTION
%Portfast will be configured in 22 interfaces due to the range
command but will only have effect when the interfaces are in a
non-trunking mode.
Setting the portfast option means
that the port starts forwarding
packets immediately instead of
waiting for spanning tree protocol
packets. This allows for less
dropped packets when a switch
first is brought online. This
explanation assumes that none of
the interfaces are running
spanning tree. All spanning treeto-spanning tree switches must not
have spanning-tree portfast
enabled. If they do have it enabled,
the interface is automatically
disabled upon receipt of a
spanning tree packet.
Displays the following output:
At this prompt... Enter... Notes
sw01(config-if-range)# switchport mode access
sw01(config-if-range)# exit
sw01(config)# interface range GigabitEthernet 2/0/2 – 24

14. Disable IGMP snooping, as follows:
At this prompt... Enter... Notes
sw01(config)# no ip igmp snooping
IGMP snooping is disabled to resolve communication issues
with the bonded 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.
If disabling IGMP snooping impacts network performance, and
if non-Cassatt Active Response applications running on the
Cassatt Active Response system do not use the multicast
functionality, disabling IGMP snooping can be done on the
control nodes only. In this case, do not disable IGMP snooping
on the switch; instead, refer to the
Configuration Guide
