Chapter 10 Managing Your Cisco ONS 15530 System
Accessing System Images on TFTP Servers
Booting from a TFTP Server
This section describes how to configure the Cisco ONS 15530 to boot a system image located on a TFTP
server. To boot the standby CPU switch module with an image located on a TFTP server, you must
configure the fastethernet-sby 0 interface with a unique IP address on a subnet separate from the subnet
used by the fastethernet 0 interface. This configuration prevents conflicts with the fastethernet 0
interface on the active CPU switch module.
Note The IP address and subnet mask must be different from the IP address and subnet mask for the
fastethernet 0 interface on the active processor
To configure booting of a system image located on a TFTP server, perform the following steps:
Command Purpose
Step 1
Switch# configure terminal
Switch(config)#
Enters global configuration mode.
Step 2
Switch(config)# config-register 0x2102
or
Switch(config)# config-register 0x0
Sets the configuration register for automatic booting.
1
Sets the configuration register for manual booting.
Step 3
Switch(config)# boot system tftp:filename
[ip-address]
Enables booting a system image located on a TFTP
server for automatic booting.
Step 4
Switch(config)# interface fastethernet 0
Switch(config-if)#
Enters interface configuration mode for interface
fastethernet 0, the NME interface on the active CPU
switch module.
Step 5
Switch(config-if)# ip address ip-address
subnet-mask
Specifies the IP address and IP subnet mask for the
active NME interface.
Step 6
Switch(config-if)# speed {10 | 100 | auto} Specifies the transmission speed. The default is auto
(autonegotiation).
Step 7
Switch(config-if)# duplex {auto | full | half} Specifies the duplex mode. The default is auto
(autonegotiation).
Step 8
Switch(config-if)# exit
Switch(config)#
Exits interface configuration mode and returns to
global configuration mode.
Step 9
Switch(config)# interface fastethernet-sby 0
Switch(config-if)#
Enters interface configuration mode for interface
fastethernet-sby 0, the NME interface on the standby
CPU switch module.
Step 10
Switch(config-if)# ip address ip-address
subnet-mask
Specifies the IP address and IP subnet mask for the
standby NME interface.
Note The IP address and subnet mask must be
different from the IP address and subnet mask
for the NME interface on the active processor.
