Chapter10 Managing Your Cisco ONS 155 30 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 fastethernet0 interface. This configuration prevents conflicts with the fastethernet0
interface on the active CPU switch module.
Note The IP address and subnet mask must be different from the IP add re ss and sub ne t ma sk fo r th e
fastethernet0 interface on the active processor
To configure booting of a system image located on a TFTP server, perform the following steps:
Command Purpose
Step1 Switch# configure terminal
Switch(config)#
Enters global configuration mode.
Step2 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.
Step3 Switch(config)# boot system tftp:filename
[ip-address]Enables booting a system image located on a TFTP
server for automatic booting.
Step4 Switch(config)# interface fastethernet0
Switch(config-if)#
Enters interface configuration mode for interface
fastethernet0, the NME interface on the active CPU
switch module.
Step5 Switch(config-if)# ip address ip-address
subnet-mask Specifies the IP address and IP subnet mask for the
active NME interface.
Step6 Switch(config-if)# speed {10 | 100 | auto} Specifies the transmission speed. The default is auto
(autonegotiation).
Step7 Switch(config-if)# duplex {auto | full | half} Specifies the duplex mode. The default is auto
(autonegotiation).
Step8 Switch(config-if)# exit
Switch(config)#
Exits interface configuration mode and returns to
global configuration mode.
Step9 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.
Step10 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.
