4.Back up the affected management station configuration files:

#cp -p /etc/nsswitch.conf /etc/nsswitch.conf.SAV

#cp -p /etc/hosts /etc/hosts.SAV

5.On a host connected to the same subnet as the switch, edit the /etc/ethers file by adding the MAC address and switch name.

For example:

8:0:20:7d:93:7e switch-name

In this example:

■8:0:20:7d:93:7e is the MAC address

■switch-nameis the name of the switch you are installing.

6.Edit the /etc/hosts file with the IP address and switch name. For example:

192.129.122.111 switch-name

In this example, 192.129.122.111 is the assigned IP address.

7.Edit the /etc/nsswitch.conf file to reference the local system files.

To ensure that the Solaris software environment uses the changes made to

/etc/ethers and /etc/hosts files, edit the host and ethers entries in the

/etc/nsswitch.conf file so that the files parameter appears before the

[NOTFOUND=return] statements.

hosts: nis files [NOTFOUND=return]

ethers: nis files [NOTFOUND=return]

8.Determine whether the RARP daemon is running by typing:

#ps -eaf grep rarpd
