Cisco LightStream 2020 Installation Manual page 27

Configure the Chassis Secondary IP address (for use by a network processor
while acting as backup). This address should be an address on the subnetwork
connecting all network processors in your network.
Chassis Secondary IP Address [a.b.c.d]: 192.1.1.12
Your system may be attached to an external Ethernet LAN by means of the
on-board Ethernet LAN interface on the network processors.
In a redundant configuration with two network processors, if the network
processors are each attached to an external Ethernet LAN by means of the
on-board Ethernet LAN interfaces, the two network processors should each be
attached to the same Ethernet LAN.
If the network processors are attached to an Ethernet LAN, you will be asked
to provide the IP address and IP subnet mask of the network processors'
on-board Ethernet LAN interface.
Are the two network processors attached to an Ethernet LAN (Y/N)? [N] Y
In a redundant configuration with two network processors, the primary
(active) network processor provides the logical connection to the attached
Ethernet LAN. Thus you will be asked to specify only one IP address and mask.
Configure the IP address for the network processors' Ethernet LAN interface.
Network Processor Ethernet IP Address [a.b.c.d]: 197.112.23.12
Configure the IP subnet mask for the network processors' Ethernet LAN
interface.
Network Processor Ethernet IP Mask [a.b.c.d]: 255.255.255.0
Is there an IP router on the attached Ethernet LAN (Y/N)? [N] Y
Configure the Default IP router for the network processors' Ethernet LAN
interface.
Network Processor Ethernet Default IP Router [a.b.c.d]: 197.112.23.1
CHASSIS INFORMATION
Host Name:
Chassis Primary (Active) IP Address:
Chassis Secondary IP Address:
Chassis Subnet Mask:
Network Processor Ethernet IP Address:
Network Processor Ethernet IP Mask:
Network Processor Default IP Router:
Chassis configuration contains 2 redundant network processors.
Network processors' on-board Ethernet LAN interfaces are attached to an
external Ethernet LAN.
Is the chassis and network processor information correct? (Y/N) [Y] Y
If you confirm that the configuration data you have entered in this step is correct by
responding to this query, the script continues with the trunk port configuration query
Y
below.
