Configuring IP Addressing

IP Configuration

then the switch uses this gateway, even if a different gateway is received via DHCP or Bootp on the primary VLAN. (This is also true for TimeP and a non- default Time-To-Live.) See “Notes” on page 8-4and refer to the chapter on Virtual LANs in the Advanced Traffic Management Guide.

Packet Time-To-Live (TTL) . This parameter specifies how long in sec­ onds an outgoing packet should exist in the network. In most cases, the default setting (64 seconds) is adequate.

Just Want a Quick Start with IP Addressing?

If you just want to give the switch an IP address so that it can communicate on your network, or if you are not using VLANs, HP recommends that you use the Switch Setup screen to quickly configure IP addressing. To do so, do one of the following:

■Enter setup at the CLI Manager level prompt.

HPswitch# setup

■Select 8. Run Setup in the Main Menu of the menu interface.

For more on using the Switch Setup screen, see 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.

■ 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, (packet) Time-

 

To-Live (TTL), and Timep via DHCP or Bootp. (Other VLANs can also use

 

DHCP or BootP to acquire IP addressing. However, the switch’s gateway,

 

TTL, and TimeP values will be acquired through the primary VLAN only.)
