Configure an Oracle Solaris System for a Point-to-Point Connection

Language:

As superuser, use the dladm command to find an unused Ethernet interface.

In the following example, the dladm command lists two Gigabit Ethernet interfaces (ce0 and ce1) and the ifconfig command shows that only the ce0 interface is being used. Refer to the dladm(1M) and ifconfig(1M) man pages for more information.

# dladm show-link
ce0             type: legacy    mtu: 1500       device: ce0
ce1             type: legacy    mtu: 1500       device: ce1
# ifconfig -a
 lo0: flags=2001000849 <UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
 ce0: flags=1000843 <UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
 inet 192.0.2.253 netmask ffffff00 broadcast 192.0.2.255
 ether 0:3:ba:7:84:5e

Use the ifconfig command to plumb the unused network interface.
```
# ifconfig interface plumb up
```
Replace interface with the network interface device (for example, ce0, hme0, qfe1, and so on). For example, to plumb an unused ce1 interface, type:
```
#ifconfig ce1 plumb up
```

Use the ifconfig command to assign an IPv4 address and netmask to the interface.
# ifconfig interface IPv4-address netmask +netmaskbroadcastbroadcastup

Replace:
- interface with the network interface device
- IPv4-address with an address between 192.0.2.2 and 192.0.2.255
- netmask with 255.255.255.0
- broadcast with 192.0.2.255
  Note - These IP addresses are examples. Use the address ranges provided by your network administrator.
  
  For example:
  
  # ifconfig ce1 192.0.2.5 netmask + 255.255.255.0 broadcast 192.0.2.255 up
  
  Note - Network interfaces explicitly configured using the ifconfig command do not persist across system reboots. If you prefer, refer to the Oracle Solaris documentation for information about setting a static IP address permanently.

Connect the PDU to the network.
