IP Configuration

Menu: Configuring IP Address, Gateway, and Time-To- Live (TTL)

Do one of the following:

■To manually enter an IP address, subnet mask, set the IP Config parameter to Manual and then manually enter the IP address and subnet mask values you want for the switch.

■To use DHCP or Bootp, use the menu interface to ensure that the IP Config parameter is set to DHCP/Bootp, then refer to “DHCP/Bootp Operation” on page 8-12.

	To Configure IP Addressing.
	1. From the Main Menu, Select.
	2. Switch Configuration …
	5. IP Configuration

N o t e s	If multiple VLANs are configured, a screen showing all VLANs appears instead
	of the following screen.
	The Menu interface displays the IP address for any VLAN. If you use the CLI
	to configure the IP address on a VLAN, use the CLI show ip command to list
	them. (Refer to “Viewing the Current IP Configuration” on page 8-6.)

For descriptions of these parameters, see the online Help for this screen.

Before using the DHCP/ Bootp option, refer to “DHCP/Bootp Operation” on page 8-12.
