Solaris Netowk Configuration/Network Failover Switch

Network Configuration Overview

2 - Modes

1. Local Files Mode - Config is defined statically via key files

2. Network Client Mode - DHCP is used to auto-config interface(s)

Check the network interfaces on the server:

anyunix# ifconfig -a

bge0: flags=1000843 mtu 1500 index 2

inet 192.168.1.50 netmask fffffff0 broadcast 192.168.1.255

ether 0:3:ba:a5:f9:43

bge1: flags=1000842 mtu 1500 index 3

inet 0.0.0.0 netmask 0

ether 0:3:ba:a5:f9:44

Note that , here the network interface is bgeX, in some machines, the network interface may be ceX .

In case, if there is only one network interface is invisible, issue the following command to enable all available network interfaces:

anyunix# ifconfig -a plumb

(or)

To enable a particular network interface , ifconfig plumb

Example : ifconfig bge1 plumb

To configure the bge1, follow the instructions below:

anyunix# ifconfig bge0 down

anyunix# ifconfig bge1 192.168.1.100 up ; Verify the IP

anyunix# dladm show-dev

LINK CLASS MTU STATE OVER

bge1 phys 1500 up --

4. anyunix# ifconfig bge1

bge1: flags=1000843 mtu 1500 index 3

inet 192.168.1.100 netmask ffffff00 broadcast 192.168.1.255 ether 0:3:ba:a5:f9:44

5. anyunix# cd /etc

anyunix# echo "192.168.1.100" > hostname.bge1 && echo $?

or

anyunix# echo "anyunix" > hostname.bge1 && echo $?

Note : 1.Currently hostname.bge0 contains its hostname “anyunix”.

2.Rename hostname.bge0 as hostname.bge0.bak

6. Restart the network service or reboot the server :

anyunix# svcadm restart network/physical

Reference Notes:

Default Gateway File- /etc/defaultrouter

Hosts database - /etc/hosts or /etc/inet/hosts

Netmask - /etc/inet/netmasks

Nodename - /etc/nodename
