Automatic IP Configuration using DHCP
When you use the automatic IP configuration method, the switch tries to obtain its IP information without requesting user intervention from a DHCP server on the network.
You should use the automatic IP configuration method if:
z

Your network uses DHCP to allocate IP information, or
Flexibility is needed. If the switch is deployed onto a different subnet, it will automatically reconfigure itself with an appropriate IP address, instead of you having to manually reconfigure the switch.
You can use ip address
Manual IP Configuration
When you configure the IP information manually, the switch remembers the information that you enter until you change it again.
You should use the manual IP configuration method if:

You do not have a DHCP server on your network, or
You want to remove the risk of the IP address ever changing, or Your DHCP server does not allow you to allocate static IP addresses.
For most installations, 3Com recommends that you configure the switch IP information manually. This makes management simpler and more reliable as it is not dependent on a DHCP server, and eliminates the risk of the IP address changing.
You can use ip address command to configure the static IP for your switch through the Console Port (see CLI Reference Guide).
