Configuring the Switch
IP Configuration
Configuring the switch with an IP address expands your ability to manage the
switch, and also enhances the switch features that can be used.
The switch console screen enables you to configure the initial values for:
■ IP address, subnet mask, and (optionally) the gateway address for the
switch so that it can be managed in an IP network
■ The time server information (used if you want the switch to get its time
information from another device operating as a Timep server)
The web browser interface screen enables you to modify the initial IP
configuration if needed.
Note If you change the IP address through the web browser interface, the browser
will lose connection to the switch. You can reconnect by entering the new IP
address as the URL.
By default, the switch is configured to receive IP addressing from a DHCP/
Bootp server that you have configured correctly with information for your
switch. (Refer “DHCP/Bootp Operation” on page 6-9 for information on setting
up automatic configuration from a server.) Through the web browser interface
or switch console, you can manually enter a different address, or you can
disable the IP operation.
Notes ■ If VLANs are not configured, then configure one IP address for the entire
switch. If VLANs are configured, then configure an IP address for each
VLAN. This is because each VLAN is a separate network and requires a
unique IP address, and subnet mask. A gateway (IP) address is optional.
For more on VLANs, refer to “Virtual LANs (VLANs)” on page 6-51.
■ The IP addressing used in the switch should be compatible with your
network: the IP address must be unique, and the subnet mask must be the
same for all devices on the same IP network.
■ If you plan to connect to other networks that use globally administered
IP addressing, refer to “Globally Assigned IP Network Addresses” on page
6-13.
For information on how IP addressing affects switch performance, refer to
“How IP Addressing Affects Switch Operation” on page 6-8.
