Setting Up Your Switch

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 or BootP server, and eliminates the risk of the IP address
changing.

To manually enter IP information for your switch, work through the “Manually

Automatically Configuring the IP Address using DHCP
By default the switch attempts to configure its IP Information by obtaining an IP
address from a DHCP server on the network.
address from a DHCP server on the network.
When using automatic IP configuration it is important that the switch’s IP address
is static, otherwise you will not know what the IP address is and it will be difficult
to manage that switch. Most DHCP servers allow you to configure static IP
addresses. Refer to the DHCP server’s documentation for instructions.

You should use DHCP to automatically configure the IP address infomration if:
■
Your network uses DHCP to allocate IP information.

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.

If you use the automatic IP configuration method, you need to discover the
