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
site for recommended switch hardware), use this Cisco switch configuration
as a guideline.
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.
Cassatt tested the switch with an RJ-45 cable with reversed pins connected to a Lantronix
ETS terminal server. The following Lantronix port settings were used:
Char Size/Stop Bits: 8/1 Input Speed: 9600
Flow Ctrl: None Output Speed: 9600
Parity: None Modem Control: None
Access: Remote Local Switch: None
Backward: None Port Name: Port_10
Break Ctrl: Local Session Limit: 4
Forward: None Terminal Type: Soft()
Preferred Services: (Lat)
(Telnet)
Authorized Groups : 0
(Current) Groups : 0
Characteristics: Broadcast Loss Notify Verify Remote Conf

2. Log into the terminal server.
3. Connect to the Cisco switch via the terminal server console.
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 port-
security.” Doing so may prevent
Cassatt Active Response
from inventorying VMs during the
discovery process.
