HP ProCurve 2520 IP Addressing with Multiple VLANs, N o t e s

Configuring IP Addressing

For more on using the Switch Setup screen, refer to the Installation and

Getting Started Guide you received with the switch.

	IP Addressing with Multiple VLANs
	In the factory-default configuration, the switch has one, permanent default
	VLAN (named DEFAULT_VLAN) that includes all ports on the switch. Thus,
	when only the default VLAN exists in the switch, if you assign an IP address
	and subnet mask to the switch, you are actually assigning the IP addressing
	to the DEFAULT_VLAN.
N o t e s	■ If multiple VLANs are configured, then each VLAN can have its own IP
	address. This is because each VLAN operates as a separate broadcast
	domain and requires a unique IP address and subnet mask. A default
	gateway (IP) address for the switch is optional, but recommended.
	■ In the factory-default configuration, the default VLAN (named
	DEFAULT_VLAN) is the switch’s primary VLAN. The switch uses the
	primary VLAN for learning the default gateway address. The switch can
	also learn other settings from a DHCP or Bootp server, such as (packet)
	Time-To-Live (TTL), and Timep or SNMP settings. (Other VLANs can also
	use DHCP or BootP to acquire IP addressing. However, the switch’s
	gateway, TTL, and TimeP or SNTP values, which are applied globally, and
	not per-VLAN, will be acquired through the primary VLAN only, unless
	manually set by using the CLI, Menu, or web browser interface.(If these
	parameters are manually set, they will not be overwritten by alternate
	values received from a DHCP or Bootp server.) For more on VLANs, refer
	to the chapter titled “Static Virtual LANs” in the Advanced Traffic Man­
	agement Guide for your switch.

The IP addressing used in the switch should be compatible with your network. That is, the IP address must be unique and the subnet mask must be appropriate for your IP network.

If you change the IP address through either Telnet access or the web browser interface, the connection to the switch will be lost. You can reconnect by either restarting Telnet with the new IP address or entering the new address as the URL in your web browser.
