Chapter 2 Configuring General Switch Features
Setting the LAN IP Addresses
The following example shows all options.
8850_NY.7.PXM.a > bootChange
'.' = clear field; '-' = go to previous field; ^D = quit
boot device : lnPci
processor number : 0
host name :
file name :
inet on ethernet (e) : 172.29.52.6
inet on backplane (b):
host inet (h) : 0.0.0.0
gateway inet (g) : 172.29.52.1
user (u) :
ftp password (pw) (blank = use rsh):
flags (f) : 0x0
target name (tn) : ??????????

Note The only two options that must be set to support the boot IP address are inet on ethernet (e) and
gateway inet. The bootchange command operates only on the active card. If you are having
trouble bringing up a standby card, you can set the boot IP address with the sysChangeEnet
command as described in the “Troubleshooting Upgrade Problems” section in Appendix A,
“Downloading and Installing Software Upgrades,” If you set the boot IP address on the standby
card with the sysChangeEnet command and it is different from the IP address set with the
bootchange command on the active card, the standby card will start using the boot IP address
set with the bootchange command when it reaches standby mode.
Step 3 Accept, clear, or change option values as necessary until the inet on ethernet option appears. Table 2-9
defines the options that you can change.
Table 2-9 bootChange Command Option Descriptions
Option Description
boot device The lnPci value selects an external server as the boot source when the boot
or runtime software is not found on the PXM45 hard disk.
processor number Do not change this option.
host name The host name identifies an external server that has switch boot and
runtime software.
file name This option defines the path and filename of the runtime software on a
remote server.
inet on ethernet This option selects the boot IP address and network mask for the PXM45
you are configuring. (This PXM45 is identified in the switch prompt.)
Enter the address and mask in the format: a.b.c.d:w.x.y.z, where a.b.c.d is
the IP address and w.x.y.z is the network mask.
inet on backplane Do not change this option.
host inet The host inet option defines the IP address for the external server that has
boot and runtime software for the switch.
gateway inet The gateway inet option identifies the IP address for the default gateway
on the subnet that hosts the switch.
